Best Lawn Mower and Tractor Batteries. Types, Sizes, and Replacements

A lawn mower, tractor, and garden starting batteries are used for starting/cranking internal combustion engines and sometimes for powering other electric loads, including lights, smaller winches, various pumps, and similar devices.

When looking for a new battery, one must pay attention to several details in order to get the right battery that will serve well for years ahead.

Intro to Lawn Mower, Lawn Tractor, and Garden Starting Batteries

Riding lawn mowers, lawn tractors, power generators, and other tools and appliances are commonly powered by internal combustion engines, which use small rechargeable batteries for starting.

Most of such vehicles, tools, and appliances also feature a manual recoil starting system, but it is much more convenient to press the button or turn the key and start the engine. just like in cars.

The size of the internal combustion engines found in power generators, lawn mowers, and tractors vary from just 2-3 HPs to large 30-40 HP gas engines powering large riding lawn mowers.

And because of that, starting batteries used in such vehicles and devices vary from small batteries being able to provide a few dozen of CCA Amps to larger batteries being able to crank even a smaller car.

When looking for a lawn mower battery replacement, there are a few things to consider first:

Battery Voltage: Is a riding lawn mower battery a 12-volt battery?

Most riding lawn mowers use 12V batteries, but there are also some models, especially smaller ones, that use 6V batteries.

Since most manufacturers tend to move to 12V electric systems, in this article, we are going to discuss only 12V batteries.

Battery Chemistry Types

There are basically two types of batteries used as starting batteries. lithium and lead-acid batteries.

Lithium batteries, even Lithium Iron Phosphate (LiFePO4) batteries, are rather sensitive power sources that feature Battery Management Systems (BMS) that make their use much safer since BMS protects the battery from unwanted events like overcharge, over-discharge, over-current, short-circuit, over-temperature, etc.

Thanks to the built-in BMS, lithium batteries can be recharged using onboard alternators and often using older style lead-acid battery chargers (model dependent), but they should NOT be recharged using modern intelligent lead-acid battery chargers. such chargers can even damage the BMS system and void the lithium battery warranty.

Although lithium starting batteries are several times lighter than lead-acid batteries, weight savings for lawn mowers and tractors, and other similar vehicles and garden tools and appliances are not worth the price difference and potential complications. IMHO, of course.

When compared with lithium batteries, lead-acid batteries are much heavier, have issues with capacity decrease when being discharged with strong currents, don’t support a large number of charging/discharging cycles, etc.

But, as starting batteries, lead-acid batteries are very reliable, robust, and very tolerant to charging conditions, and they are mostly cheaper than lithium batteries.

Lead-acid batteries differ in design and can be wet/flooded, enhanced wet/flooded, Absorbent Glass Mat (AGM), and Gel-Cell batteries.

Since AGM and Gel-Cell batteries are spill-proof and maintenance-free batteries, they are recommended models for lawn mowers, lawn tractors, power generators, etc.

Terminal Position and Type

Batteries come with different terminal types and with different terminal orientations.

When buying a new battery, be sure that the terminals and the orientation of the new battery match the terminal type and orientation of the old battery.

best, lawn, mower, tractor

If they don’t, one may have issues connecting the new battery. If that happens, the workaround is to use cable extensions and terminal adapters.

However, the best thing to do is to get the battery with the same terminal type and orientation.

Fortunately, most starting batteries come with standardized terminals depending on their size/group.

Cold Cranking Amps (CCA)

CCA (Cold Cranking Amps) is the maximum current that a new, fully charged, 12V battery can deliver for 30 seconds, with the voltage NOT dropping below 7.2V, at 0°F (-18°C).

The new battery replacement for starting applications should have the same or better CCA rating in order to perform well.

Battery Capacity (Ah)

The capacity of lead-acid batteries is determined by how many amps of current can new, fully charged 12V battery at 80°F (~25°C), deliver for 20 hours without its voltage falling below 10.5V.

The capacity of starting/cranking batteries is often given for a period of 10 hours and not 20 hours. they are, after all, not designed nor intended for deep discharge applications.

Reserve Capacity (RC)

RC (Reserve Capacity) is the number of minutes that a new, fully charged battery (at 80°F, ~25°C) can deliver a 25A current and maintain a voltage above its cut-off value (10.5V for lead-acid batteries).

RC value is important for deep cycle batteries used in marine applications (for trolling motors, for example), RVs (in-house batteries), solar systems (off-the-grid applications), etc., and not so for riding lawn mowers, lawn tractors, and similar.

Of course, sometimes there are other things to consider when buying a new lawn mower battery, but these are the most important ones.

How to Charge Lawn Mower and Tractor Batteries

Lawn mower and tractor starting batteries are charged via an onboard alternator and charge controller, if present. Whenever the engine is turned On, the alternator recharges the battery and keeps it fully charged.

When the batteries are being charged separately, it is important to use a proper battery charger:

When wintering the lawn mowers and tractors with internal combustion engines, it is a good practice to recharge the battery fully and connect it to the battery maintainer during the storage period.

Lithium batteries generally have a much lower self-discharge rate than lead-acid batteries and can be left in the lawn mower and/or tractor for a longer period of time without recharging. as long as the parasite loads are minimum, preferably zero.

Lithium YTX14-BS batteries are gaining in popularity, but AGM YTX14-BS batteries are still a much more popular type.

Manufacturers of lithium starting batteries, YTX14-BS size included, often label their batteries with the ‘lead-acid equivalent’ capacity, although their batteries have a much smaller actual capacity.

Although actual capacity is of lesser importance for starting batteries, parasite loads may discharge smaller capacity lithium batteries much faster than the larger lead-acid AGM and Gel-Cell batteries.

To prevent issues due to the parasite loads, some manufacturers include in their lithium batteries over-discharge protection with the Reset Button. when the parasite loads discharge the battery too low, BMS cuts off the battery from the vehicle. By pressing Reset Button, the user can activate the battery, which still has enough charge left to more or less safely crank the engine.

Note: Such system is NOT present in all lithium starting batteries, YTX14-BS batteries included.

YTX12-BS batteries are very similar in size to YTX14-BS batteries. their physical dimensions are 5.875 x 3.5 x 5.125 inches (150 x 88 x 130 mm).

Lead-acid YTX12-BS batteries feature a 10h capacity of ~10 Ah, CCA rating in the 180-210 Amps range, and weigh 7-10 pounds.

Since YTX12-BS batteries are very popular Motorsport/Powersport batteries, many manufacturers also offer lithium YTX12-BS starting batteries which offer weight savings of 6-7 pounds, smaller capacity, but a better CCA rating of 250-500 Amps.

For high-performance and professional applications, lithium YTX12-BS batteries are highly recommended, but for residential riding lawn mowers and tractors, a good AGM or Gel-Cell YTX12-BS battery is the way to go.

The following cross-reference chart lists some of the most popular AGM, Gel-Cell, and Lithium YTX12-BS batteries with their most important features and specifications:

Although their capacity is relatively small, AGM and Gel-Cell YTX12-BS batteries are often used even in deep discharge applications, like small kayak trolling motor batteries for quick hops from one position to another, as a fish-finder battery, small inverter batteries, and similar.

Although starting AGM and Gel-Cell batteries are much more tolerant to deep discharges than wet/flooded starting batteries, they should not be used as such. a few cycles down to 50-80% DoD will not harm these batteries if they are soon after the discharge cycle recharged (preferably) using a Smart AGM/Gel-Cell battery charger.

Also, be aware that a semi-discharged lead-acid battery is unable to provide as strong starting current as a fully charged battery.

Best Group YTX9-BS Battery Equivalents and Replacements

Lawn Mower and Tractor Batteries Frequently Asked Questions (FAQ)

Here are some of the most common Frequently Asked Questions (FAQ) about lawn mower and tractor batteries and starting batteries in general.

What kind of battery do I need for my riding lawn mower?

Riding lawn mowers require small lead-acid or lithium starting batteries. exact battery size differs, so it must be checked for each lawn mower/tractor.

How long does a lawn tractor battery usually last?

A lawn tractor battery may last a few years, depending on the use and maintenance. if the lawn tractor is stored with the battery connected to the maintainer, such battery usually lasts a few years longer.

Is a riding lawn mower battery a 12-volt battery?

Most riding lawn mowers come with 12-volt electric systems, batteries included. But, just in case, check the Owner’s Guide of the lawn mower that You have.

How to charge a lawn tractor battery?

The lawn tractor battery is charged via an alternator connected to the lawn tractor engine. However, if the unit is not used periodically, it is a good practice to recharge the battery from time to time with a good battery charger and to store the lawn tractor with its battery connected to the battery maintainer.

Some smaller and older units don’t feature onboard battery chargers, requiring users periodically to recharge them using Smart battery chargers, usually in the 1-5 Amps range.

Such batteries should be recharged every 2-3 months or when cranking becomes difficult and slow.

Will a lawn mower battery start a car?

It depends on the size of the battery and the size of the car’s engine. Smaller lithium starting batteries will NOT start car engines since their BMS will disconnect the battery due to the too-strong current.

Smaller lead-acid batteries may even start a car engine, but that would be really too big load for smaller lead-acid batteries, shortening their lifetime.

Larger starting lead-acid batteries found in larger lawn mowers and tractors may start the car’s engine, although they are not intended for such use. it all depends on the battery size, its condition, CCA, and the size and type (gas, diesel) of the car’s engine, external temperature and similar.

Are tractor batteries the same as car batteries?

Tractor batteries and car batteries are of the same type and internal construction, but car batteries are generally larger.

P.S. yes, Yugo 45 is also considered a car, but its engine can be started with a larger lawn mower/tractor battery easily.

Can you use a car battery to charge a lawn mower battery?

If the fully charged car battery is connected to the discharged lawn mower battery (both batteries are of the same type/chemistry), some of the car’s battery charge will be transferred to the lawn mower battery.

However, initial charging currents can be rather large and may even damage the lawn mower battery.

If lawn mower/tractor battery charging is required, charge the lawn mower/tractor batteries using advanced battery chargers that monitor the battery condition and adjust the charging process according to the battery condition.

When should I replace my riding mower battery?

If the lawn mower/tractor features a battery charging system (alternator charge controller) and when:

  • the engine start becomes sluggish and slow,
  • the lights are dim,
  • the battery voltage is constantly around or below 12V with the engine Off,

If the lawn mower/tractor doesn’t feature a charging system, take the battery out, recharge it completely and check how it performs. if it shows signs of a weak battery (slow and sluggish starts, dim lights, etc.), it is time to replace the battery.

Can you put a car battery in a lawn tractor?

Car batteries are generally too large for lawn tractors and cannot fit the lawn tractor‘s battery compartment.

But, even if it is possible to put a car battery in a lawn tractor, don’t forget that too large battery can lead to alternator failure. whenever replacing the lawn tractor/mower battery, check the documentation that came with the unit and use replacement battery as recommended by the manufacturer.

Few Final Words

When looking for a new lawn mower replacement battery, be sure to match the old one regarding battery type/chemistry, size, terminal orientation, and terminal type.

Both the capacity and CCA rating of the new battery should be the same or better than the capacity and CCA rating of the old battery.

When wintering your lawn mower, check its Owner’s Guide regarding battery maintenance. if allowed by the lawn mower manufacturer, disconnect the battery (if there are no parasite loads, there is no need to disconnect the battery) and keep it charged using a Smart battery charger/maintainer.

During the summer heat, keep the lawn mower in the shade or preferably in the air-conditioned garage/storage room.

Note: internal combustion engines should be operated only in the open, not in garages, storage sheds, or similar, regardless of how good ventilation is. internal combustion engines produce colorless and tasteless Carbon Monoxide (CO), which is a very dangerous gas for humans and animals.

Also, these batteries often look like toys, but they pack quite a strong punch!

Husqvarna Lawn Xpert Battery-Powered Mower

A worthy competitor in the electric OPE market, Husqvarna has added a 40V model to its battery-powered walk-behind lineup. The Husqvarna LE-322R Lawn Xpert Mower is part of an effort to advance the brand’s electric lawn mower formula by way of performance and design enhancements.

With that in mind, let’s see what the LE-322R has to offer weekend warriors with small- to mid-sized yards to conquer.

Husqvarna LE-322R Lawn Xpert Mower Performance

The Husqvarna LE-322R sports a brushless motor that, according to Husqvarna, gives this mower the power to chew through thick grass 30% more easily than comparable walk-behinds in its class. Likewise, its 21-inch cutting width suits homeowners with yards half an acre or less in size.

As for runtime, Husqvarna says you can expect to get about 75 minutes of cutting when using a pair of 40V BLi30 7.5 amp-hour batteries.

An active cooling system keeps the mower’s motor from running hot. This helps maintain consistent power and extended tool life.

Furthermore, the LE-322R’s self-propelled design includes a speed control similar to the one on the EGO Select Cut XP mower that enables the operator to set a walking pace of up to 4 MPH, which is on the high end of average.

Husqvarna Lawn Xpert Mower Design

The LE-322R has a number of features worth noting, starting with a series of operator controls.

This mower offers three cutting modes (auto-sensing, mulching, and boost) that you can toggle via a button on the control panel. Additionally, the design includes cutting heights from 1.5 to 4.5 inches, with 7 adjustment positions. A nifty Start button, similar to a modern keyless vehicle, gets you started.

This model’s lightweight build scales in at 80 pounds bare, while other design elements like its 8-inch front and 10-inch rear wheels allow for more rugged handling capability. over, the LED headlights make it easier to mow in low-light conditions.

Finally, the handles fold for compact or vertical storage.

Husqvarna Lawn Xpert Mower Price

The Husqvarna LE-322R retails for 599 as a bare tool and 849 as a kit, including two 40V batteries and a charger. Husqvarna backs these options with a 3-year warranty.

Lawn Tractor Won’t Start No Click – Fix it now!

Before we assume there’s a problem, let’s take a minute to check that we’re following the correct starting procedure. All mowers will have safety sensors fitted, and if the sensors are open, they won’t start.

So why won’t your lawn tractor start, not even a click? The most common reason for a no start, not even a click sound, is a totally flat battery, but other likely causes include:

A tractor mower won’t start if the blade lever/button is on, manual mowers need to be in Neutral gear, and some mowers won’t allow starting if the oil level is low or the hood is open.

If you are in any doubt about the correct starting procedure for a lawn tractor, check out – “How to Start Husqvarna Ride-on Mower.”

If you do hear a click sound when you turn the key, check out – “Mower Wont Start Just Clicks.”

Check Battery Connections

To test a battery, you need a voltmeter, but if you don’t have one, try this basic check. If your mower has hood lights or dash lights, go ahead and turn them on. If they light up and are bright, your battery is most likely not the problem.

Dash Lights are Dim

Check – Check the battery cables; they should be clean and tight. When connections are loose or corroded, it prevents available power from flowing to the starter.

Charge Battery – If your battery is completely flat, it will take a couple of hours and will require a battery charging hack, or check out this Smart battery charger the NOCO Genius1 on

Jumpstart Mower – This is the fastest solution, but it may not be the long-term fix. (see Jump starting below)

Battery Check Hack

  • Turn on the lights to check for power supply
  • If they work – the battery is likely OK
  • If lights are dim – check battery cables
  • If cables clean and tight – charge battery
  • If you have no lights – check battery with a volt meter

Volt Check – Need a voltmeter for this test. Check b attery voltage – 12.65v is 100%, 12.30v is 70%, and 12.05v is 50% charged. This battery needs a charge.

Very low volts indicate the battery is likely faulty, and it may not recharge. To test a battery, it must be charged, so a battery charger may be required. However, it is possible to jump-start the mower (see below), and given time, the mower’s alternator will charge the battery, assuming it isn’t faulty.

Once the battery is sufficiently charged (about 70%), try the crank test.

Battery Crank Test – Attach the Voltmeter and crank over the engine; if the volts read less than nine, replace the battery. (The battery must be over 70% charged for running this test)

Check out the Amazon link below for quality mower batteries delivered to your door.

Voltmeter – If the lights don’t work at all, you’ll need to use a voltmeter to check the battery’s state of charge. You may have blown a fuse (see below).

If you have very low volts, the battery is likely faulty. The average life of a battery is four years, more if well cared for.

Jumper Cables

If you don’t have a charger, you can still get it running, but you’ll need a set of jumper wires, and a car or any 12-volt battery will do the job. Follow this link for a more detailed guide to Jump Starting.

Jumpers – Use good quality jumpers.

If you are unfamiliar with jump-starting, you’ll find a complete guide here, “Jump starting riding mower.”

Add the cables in sequence 1, 2, 3, and 4 to start the mower, and while idling, remove jumper cables in reverse order 4, 3, 2, and 1.

Dash Lights Don’t Work

Main Fuse – If the battery is fully charged and still no go – check the main mower fuse. Some mowers will have the blade-type fuse; others will have the old-style bottle type.

When the fuse blows, all power is lost; changing it is simple. It is important to replace the fuse with the correct amp rating. If the fuse keeps blowing, the rating is too low, or there’s a short-to-ground wiring fault.

Fuse Location – Places they like to hide include under-seat, under the hood, behind the fuel tank, and control module incorporated. Modules are usually under the dash panel.

Replacing the fuse is simple, just pull out the old one and push the new one into place. It’s important to replace it with the correct amp rating. Otherwise, you can damage the wiring circuit and components.

Check Safety Sensors

Riding mowers are designed with safety features built in to protect us from operator error or accident. Safety features on mowers are controlled by sensors/switches, and most modern mowers will wire those sensors into a control module.

The sensors are a very simple on/off switch type and rarely give trouble; it’s more common for the striking plate that pushes on the sensor to be misaligned; when this happens, the sensor is open, and the engine won’t start or stops depending on where the sensors fitted.

Over-riding – Sensors can be overridden for test purposes, remove and join the wires, and some sensors are wired in reverse – meaning, just disconnecting them will override the sensor. You can check sensors for continuity using a voltmeter.

Starting Procedure

As you know, there’s a starting procedure that must be followed before your mower will start. You can check out the starting procedure here – “How to Start a Husqvarna Ride-on Mower.”

There are several sensors that must be engaged; the location and number of sensors are dependent on the make of the mower and differs between manual and hydro-static (type of transmission).

The main sensors are the brake pedal; seat; gear lever; blade engage control switch or lever, and some models, such as John Deere, will have one fitted to the hood (Hood open – no start).

Safety – For our safety, sensors are fitted to the seat, blade engages lever or button, transmission selector, brake pedal, and on some models, the hood. Any of these sensors will prevent your mower from starting.

On older manual transmission mowers, the gear selector wears, and although the selector points to the Neutral position, it’s often still in gear – confirm it’s in Neutral by pushing it forward or back; it should be easy to push.

Sensors – This older style Craftsman / Jonsered / Husqvarna blade lever causes lots of no-start problems.

The lever spring gets weak and leaves the sensor in the open position which prevents starting.

Sensors – The quick fix, hold down the lever to start the mower. The complete assembly is available and not too difficult to fit. Check that all sensors are working, and look to see if the striker plates are closing the sensors fully.

Check wiring to sensors for chafing and that the connectors are secure and corrosion-free.

Check Control Module

Most modern mowers will have a Control module; they are a printed circuit with relays and resistors – they do give trouble. Because the specs vary, I can’t be more detailed.

The function of the control module is to receive a start/stop command from the ignition switch and only output a start command to the starter (via the solenoid) if all the correct sensors have been engaged.

Offers Extra Power, Durability, Features and Comfort. []

You can visually inspect the module printed circuit for loose solder, scorch marks, or water damage. All modules will have an internal or external fuse, and as you know, the main fuse can blow, and if it does, it will kill the power to the ignition system.

Modules can be fitted anywhere, usually housed inside a small rigid plastic box. but not all mowers will have one fitted.

Replacement modules can be on the spendy side, so it may be time to access your old mower; if she needs a ton of love in the blades bearing and belts department, it may be time to look at a new set of wheels.

Module – Wires come loose, have a helper attempt to start the engine while you wiggle the wiring connectors.

Check also for damage, water, or scorch marks on the panel itself.

Check Ignition Switch

Ignition switches are an important part of the ignition system; bad connections here can cause lots of problems. Ignition switches – send commands to the control module if fitted.

If your mower doesn’t have a control module, then the safety sensors are wired inline to the ignition switch – meaning any sensor that is in the open position will leave the ignition switch with an open circuit (No start). These systems are basic and tend to be the most reliable.

Common Problems

Issues with ignition switches: loose wiring at the switch; corroded terminals; broken terminals; spinning ignition switches.

Wiring specs for ignition systems vary, so I can’t be more detailed. Check the ignition wiring for damage, corrosion, or loose wires. Have a helper sit on the mower and attempt a start while you wiggle the ignition wires and connectors.

  • Check ignition inputs – ground and 12-volt supply.
  • Check ignition outputs – 12v to the starter solenoid (or to the control module, if fitted) when the ignition is in the start position.

Switch – Spinning ignition switches cause damage to the wiring and pins.

Corrosion is another common failure. This usually causes unreliable starting and shutdowns.

Wiggle – Try wiggling the wires at the back of the ignition switch while attempting to start the engine; you may need a helper. Often wires simply come loose but do check them for corrosion.

Best Buy cordless mowers

Husqvarna Aspire LC34-P4A

  • Quiet
  • Cuts even long grass with ease
  • Battery level visible while mowing
  • Small and compact for easy storage
  • Part of the POWER FOR ALL cordless range

Part of the new Husqvarna Aspire cordless range, which includes a hedge trimmer, pruner and leaf blower, this 34cm mower is powered by an 18V POWER FOR ALL ALLIANCE battery and charger. These are interchangeable with tools in other leading brands such as Flymo, Gardena and Bosch so if you also invest in tools in these ranges, you’ll only need to buy the bare tool and won’t have different batteries and chargers taking up space in the shed.Great for small gardens the mower comes ready to go, there’s no assembly or handles to attach, and it folds down to a compact size when you’re finished, with a telescopic handle that folds completely flat over the body of the mower. It can then be stood up against a wall or hung up, and even comes with a handy hook. The 30l grass bag also flattens down to take up very little room and can be hung on the mower. The Aspire is light, with a carry handle so that lifting it up steps or into other areas is easy and it has an adjustable handle to suit different height users. It’s comfortable and easy to manoeuvre around the garden and has just four cutting heights to choose from, ranging from 25-65mm and changed easily with a single lever on the body of the mower. It cuts grass quietly and smoothly and has an automatic boost that increases blade speed when you’re mowing in tougher, longer areas that works well. You can hear it kick in when you push the mower into longer grass and unlike other cordless mowers that can cut out, just carries on cutting the grass. While you mow the battery charge level is always clearly visible so you know how much battery you have left and when it needs charging. It comes with a two year warranty and we awarded it a BBC Gardeners’ World Magazine Best Buy in 2023 for ease of use.

Specs: Battery: charge time. 95 mins; run time. 500sqm. Cutting: width. 34cm; height. 25-65mm. Grass box. 30 litre.
