How to Charge Your Lawn Mower Battery, Power Tools and

Behind every healthy lawn is a healthy lawn mower battery.

Actually, every house project relies on batteries. The drill you used to hang the TV runs on a battery. So does your cordless sander. Batteries take your tools farther than any cord, as long as they’re healthy.

Here’s how to get more life out of your batteries.

Why you should charge your lawn mower battery before spring

You can get years more out of your lawn mower battery, if you follow two simple steps:

Your riding lawn mower comes with the same essential parts a car has. It has an internal combustion chamber, an alternator, a 12-volt lead-acid battery, etc. A riding lawn mower with an especially small engine may have a 6-volt battery. The lawn mower’s alternator keeps its battery charged. A few hours of mowing recharges it the same way hours of highway driving can keep your car battery mostly charged.

You might not mow the lawn in winter.

That means your lawn mower battery may be totally drained.

Lead-acid batteries drain themselves when they’re not used. That’s bad news. They need to stay charged or they’ll lose the ability to hold electricity. You can try to charge them if that happens. Still, they may be too weak to start an engine.

How much longer will your lawn mower battery last?

Let’s check! Bring your lawn garden battery to any Interstate Batteries location for a battery test. Let’s see how many summers your battery has left.

Lithium-ion batteries drain themselves, too, when they’re not in use, just not as quickly. Keeping your rechargeable lawn mower fully charged for months isn’t healthy for the lithium-ion battery inside. Letting it drain to zero percent damages it, too.

Whether your lawn mower uses a lithium-ion battery or a lead-acid battery, charge it in January or February. Charging your lawn mower battery keeps it healthy for years.

• Leave the battery in the mower. You don’t have to uninstall the battery to charge it.
• Clean the terminals. Use baking soda and a dry cloth.
• Check the voltage and amp settings. Your battery’s label will say if it’s lithium-ion or if it contains lead. You’ll also see if it’s 12 volts or 6 volts. Set the charging amps to less than 2 amps if the charger has the settings for it. Charge slowly to protect the battery.
• Follow the charger’s instructions. The manual gives you any other steps your charger needs.
• Last-minute safety check. Take off jewelry. Put on gloves and safety glasses. Make sure there’s decent airflow around you.

steps to charge your lawn mower battery

A trickle charger makes it easy to keep your lawn mower battery ready. It charges lead-acid batteries for days at a time to protect the battery’s lifespan. You could leave your lead-acid lawn mower battery on the charger all winter long if it has a float setting. The charger will top off its charge for months and keep it from losing power while it sits on the shelf.

A Smart charger will recharge a lawn mower battery in hours. Adjust the voltage and amp settings if you’re charging a 6-volt lawn mower battery instead of a 12-volt one.

Want to protect your lead-acid lawn mower battery? Keep it 100 percent charged.

Want to protect your lithium-ion lawn mower battery? Leave it 70 percent to 80 percent charged while in storage. Being fully charged or totally depleted hurts lithium-ion batteries. Check the manual for charging instructions.

We’re the reason the grass is greener. Pick up an Interstate lawn garden battery to power up your lawn mower, clipper or tree trimmer.

The nice part is you can just recharge your lithium-ion lawn mower if it doesn’t start. You’ll never need to jump-start a riding lawn mower with a lithium-ion battery.

Now, you can jump a lawn mower if it has a lead-acid battery. Aquí le enseñamos cómo.

How you can safely jump-start your lawn mower battery with your car

You can jump your lawn mower with your car. It’s the same steps as a regular jump-start — with three big differences.

• Turn off the car before connecting cables to your lawn mower. The car’s alternator generates too many amps and can damage the mower’s parts, including the battery. Never jump-start a lawn mower battery from a running car. Don’t even leave the key in the ignition.
• Protect the positive cable from touching anything but the battery terminals in the car and mower. The positive cable is usually the red one. You’ll connect it first to the mower, then the car. Otherwise you could damage your car battery.
• Run the mower for at least two hours after disconnecting the cables. John Deere, Ryobi, Cub Cadet — all gas-powered riding lawn mowers have an alternator. Mowing will charge their starting battery.

Jump-starting should be the last resort. Wait if you can. Connect your lawn mower’s battery to a charger. Then do a different home project with your other power tools.

Time to talk about your other power tools.

Tips to make your power tool battery last longer

Take care of your power tool batteries, and your tools will be ready any time you need them.

Power tools run on three different types of batteries:

• Nickel cadmium or NiCd batteries
• Nickel-metal hydride or NiMH batteries
• Lithium-based, including lithium-ion or lithium-polymer batteries

Now, each battery type needs different care. It’s easy to assume one tip for one battery type will work for all batteries. The truth is each battery type needs something different.

Attention! This is not a drill!

Is your cordless drill turning into a screwdriver? Don’t toss your power tool. Let’s rebuild its battery instead. Available at select Interstate All Battery Center locations, we put the power back in your power tools.

You might be reaching for a screwdriver sooner than you expect if you give your cordless drill the wrong kind of TLC.

The right way to care for your NiCd battery

A NiCd battery needs to be run hard. Charge it up and drain it to zero percent every month or two. Then store your NiCd battery when it’s fully drained.

NiCd batteries are one of the few types that like being stored on empty. They also drain themselves quickly when they’re not in use. Don’t bother recharging it if you only used it for two minutes.

Fast charging doesn’t stress a NiCd battery. So put it on the charger right before you run your leaf blower or cordless sander. Then use every bit of energy before putting it back.

Sitting on a charger can damage a NiCd battery. Its insides can crystalize and resist turning back into electricity. That might be why your NiCd battery doesn’t last as long as it used to. A pulse charger can heal your NiCd batteries if you’ve kept it charged too long. You might not get the battery back to perfect health, though.

Instead, keep fast-charging your NiCd battery and draining it to zero.

Exercising it protects the material and gives your cordless power tool batteries a much longer lifespan.

The right way to care for your NiMH battery

A NiMH battery needs to stay out of the heat, to charge with its original charger and to be drained to zero percent every few months.

If you’re using your power drill for a few hours every day, a NiMH battery is perfect. NiMH batteries are handy for power tools. They weigh less, carry more power and last longer between charges than a NiCd battery.

They don’t do well in storage. NiMH batteries will drain themselves. It’s not as quick as a NiCd battery. All the same, you’ll want to use your NiMH-powered drill every other day to get the most life from the battery.

Recharging NiMH batteries uses a special algorithm. Don’t use a NiCd charger on a NiMH battery. It can hurt the battery’s lifespan if not overcharge it. Keep the charger that came with the power tool. You can replace it, but make sure it’s specifically made for NiMH batteries.

Mow power to your lawn mower and weed whacker battery

You just jumped your riding lawn mower? Might be time for a new battery. Go for lawn garden batteries and power tool rebuilds, available at select Interstate All Battery Center locations.

NiMH batteries struggle with heat. That’s a problem because a NiMH battery will heat up as it runs power or charges. Be gentle with it. Take it off the charger early if the case feels warm. Also, let it cool down before you recharge after it charges.

You can expect a long, full life out of your NiMH battery by keeping it in use and near its original charger.

The right way to care for your Li-ion battery

Lithium-ion batteries weigh the least and offer the longest life overall, but they’re sensitive to getting dropped, overheated or overcharged. How you protect your phone battery would work on your lithium-ion power drill:

• Keep it away from heat.
• Don’t leave it on the charger.
• Don’t let it ever run down to zero percent.

Store a li-ion battery at 80 percent power, not 100 percent. This battery type doesn’t drain itself that quickly. It’ll hold charge for weeks.

The way to take care of your lithium-ion battery is to charge it before it drops to 20 percent. Keep it charged between 40 percent and 80 percent. You can top it up to 100 percent before you sand the deck or trim the hedges. Just don’t leave it fully charged.

Staying at 100 percent corrodes the active materials, which means the battery can’t hold as much electricity as before. The same happens if it ever drains to zero, but faster. Check the power level while you work. Stop and recharge it if you’re close to 25 percent left.

Take care of your lithium-ion battery, and it’ll keep powering on.

Leaving your power tools on the charger does not help the battery.

Trying to charge a battery that’s already full can damage it. Most battery chargers will stop charging if the battery is full.

The built-in protection means it should be safe to leave it on the charger, right? Not quite.

Only lead-acid batteries like to stay fully charged. The other battery types need exercise. They’ll drain themselves, even if sitting on a shelf. That’s okay, depending on the battery type. All battery types need exercise. Leaving them on the charger robs batteries of that exercise.

A battery on the charger will go through short run-and-recharge cycles. It’ll drain to 99 percent, recharge, drain again and recharge again. Those short cycles hurt most batteries. Instead, your power tool batteries need to keep the electrons flowing.

Consider it another good reason to do those house projects today.

Revive your power tools.

All rechargeable batteries wear down. But you don’t have to throw out your favorite tool! Rebuild its battery at select Interstate All Battery Center locations.

Whether you’re switching from gas-powered to green or buying your first cordless electric mower, battery-powered lawn mowers offer many advantages. In addition to being kinder to the environment, they’re also quieter and easier to start than gas-powered mowers.

These innovative machines use powerful batteries that provide enough juice to mow lawns up to a half acre or larger. They also produce enough torque to cut through tall grass and many are self-propelled, making them easier to operate.

We tested the following battery-powered lawn mowers in different grass-growing environments to find out more about their capability, reliability, and overall user comfort. Read on to learn about the important features to consider, how to select the best battery-powered lawn mower for areas ranging from just a few square feet to a couple of acres, and how each mower performed in our hands-on tests.

How We Tested the Best Battery-Powered Lawn Mowers

Battery-powered lawn mowers generally offer a quiet, exhaust-free mowing experience. They remove the hassle of buying and hauling gasoline, changing oil, and other maintenance aspects of gas engines. With the notable exceptions of sharpening/replacing blades and charging/replacing batteries, they are virtually maintenance-free. While shoppers are motivated to buy battery-powered lawn mowers for a multitude of reasons, the expectation remains that they will be able to mow their grass whenever they want, without hassle or frustration. To us, as testers, that meant we needed to closely scrutinize runtime, recharge time, and overall mowing capability.

We tested all mowers the same way and captured the results on a testing rubric for comparison. After fully charging the batteries, we used them to mow two different areas, one that had been consistently maintained at the normal mowing height, and one that had been neglected and allowed to grow about 10 inches high. Both areas included a mix of flat and moderately sloped ground. As we mowed, we assessed general operator comfort, self-propelled capabilities, mowing power, and finished mowing quality. We mowed until the batteries ran out, recorded the runtime, and measured the area mowed. Finally, we recorded the time required to recharge the depleted batteries.

Because riding mowers offer many more features and control options, we tested the Ego Power Z6 over several days with multiple battery configurations. Battery life plays such an outsized role in overall performance and customer satisfaction that we wanted to collect results on maintained and overgrown grass for groupings of two, four, and six batteries. The testing criteria and observation points for each test run were virtually the same as those for the other mowers. The great news is that all of these mowers delivered excellent mowing power, good-to-excellent cut quality, and plenty of runtime for real-world applications as shown in the individual reviews.

Our Top Picks

We tested the following mowers taking into account the above considerations for large and small yards. Read on to learn how each model performed in testing and why we consider them among the best battery-powered lawn mowers.

Snapper XD 82V MAX Cordless 21-Inch Self-Propelled Mo

The Snapper XD features a variable-speed transmission and design features that allow for adjustments to meet different grass-cutting demands. The StepSense feature automatically adjusts the speed to match the user’s walking pace. Load-sensing technology in this model automatically adjusts power output based on the thickness of the grass to provide a clean cut while maximizing energy efficiency.

The mower’s impressive 21-inch steel cutting deck is versatile. It boasts seven height adjustments that are easily changed from behind the mower with a single lever. The deck can mulch, side discharge, or bag with a capacity of up to 2.1 cubic feet of grass clippings.

When the yard work is done, this mower folds up conveniently for vertical storage in the garage. The kit includes two 2.0-Ah (amp hour) batteries, which together provide about 60 minutes of runtime and recharge in about 60 minutes.

In our tests, the Snapper XD traversed all types of terrain and left behind a smooth, even cut on a single pass. It easily powered through overgrown grass and weeds up to 10 inches tall, although extended use in tall weeds increased the needed power output and reduced runtime by about half.

We were more impressed by the blade motor’s load responsiveness than by the automated pace-adjustment system. The StepSense feature worked well on relatively flat ground, but on inclines it felt somewhat sticky or uneven. In overall performance for the price, this mower offers excellent power and runtime to mow about ⅓ of an acre, or 15,000 square feet, per charge.

Product Specs

• Runtime/recharge time: 60 minutes/60 minutes
• Deck size: 21 inches
• Mobility: Self-propelled, automatic pace adjustment
• Automatically adjusts to any individual user’s pace
• Powerful motor doesn’t bog down in dense grass
• Single lever cutting-height adjustment for user-friendliness
• Folds into a compact unit for ease of storage
• Less runtime per charge than some competitors
• StepSense feature feels somewhat “sticky”

Greenworks Pro 80V 21-Inch Cordless Lawn Mower

Greenworks is known for its advancements in battery technology, and this model has two 2.0-Ah batteries that allow for up to 70 minutes of runtime from a full charge, with a combined recharge time of just 60 minutes. This push mower features a 21-inch-wide mowing deck. Technology that adjusts the motor speed based on load helps to maximize battery life and maintain excellent cut quality.

Adding to this impressive mowing coverage is a steel deck with seven positions that are easy to adjust with a large handle near the right rear wheel. Its sturdy steel deck gives it the tough feel of gas-powered models.

A large start button and easy-to-maneuver speed control mean it can be manipulated with gloved hands. This push mower does not have motorized wheels, which keeps the price low and maximizes battery life for cutting grass. The 3-in-1 grass clipping capability allows for bagging, mulching, or side discharging, and a foldable handle design facilitates compact storage.

Although this Greenworks push mower required a bit more effort to move around the yard than the self-propelled mowers, its simplified design made it an extremely capable mower. The powerful motor offered the most “gas-like” performance of the group. It had no trouble cutting dense, weedy grass up to 10 inches tall and left possibly the best finish of all the mowers we tested. In all three modes, bagging, mulching, and side discharging, it left the grass perfectly smooth, with no uneven spots or stringy weeds left behind. It had plenty of power to mulch thick grass into virtually invisible clippings.

The only downside of this mower was that hilly ground reduced the amount of area mowed per charge, not because of demand on the mower, but because the operator’s pace slowed. Everything else considered, we felt that this push mower delivered the strongest mowing capability, even though we had to push it. And the price was significantly less than the others.

Product Specs

• Runtime/recharge time: 70 minutes/60 minutes
• Deck size: 21 inches
• Mobility: Push
• Dual 2-Ah batteries offer up to 70 minutes of runtime; ideal for both small and large yards
• Strong motor delivers powerful cutting performance; ideal for thin and thick grass varieties
• Easy to use controls integrated into the handle
• Included charger only charges one battery at a time
• Not self-propelled; may cause some strain on the user

Toro Flex Force 60V 21-Inch Super Recycler Mower

The Toro Flex Force Super Recycler lawn mower is built for powerful mowing performance with superior operator comfort. The three-phase motor automatically increases power output when it detects tougher mowing conditions, then eases off to conserve battery life when the mowing gets easier again.

The 21-inch military-grade cast aluminum deck features a powerful vortex air-intake system that stands the grass blades up straight for a smoother, cleaner cut. The shock-absorbing Personal Pace self-adjusting, self-propelled system operates smoothly regardless of the terrain. Bright LED headlights make it easier to mow later into the evening. It comes with a powerful 60V 7.5-Ah battery that delivers up to 50 minutes of runtime per charge and recharges in 3 hours.

The Toro Super Recycler was the most comfortable battery-powered mower we tested, primarily because of its robust self-propulsion system. Although it was not the only mower with a pressure-sensitive handle, this one functioned the best. It paired the slightly more resistant, but buttery smooth, handle movement with a higher top-end speed for self movement that felt almost effortless on most terrain. Only slight pressure was required to climb the uphill areas, and it didn’t try to run away on the downhills.

Toro’s excellent cut quality was second only to the Greenworks 80V (mainly because the Greenworks mower performed exceptionally well in overgrown areas and Toro needed a second pass for best results there). However, we were underwhelmed by its battery performance at only 45 to 50 minutes of runtime in average conditions and 3 hours to recharge. Still, anyone with less than a half acre who is shopping for smooth operation and a top-quality cut may want to consider the Super Recycler.

Product Specs

• Runtime/recharge time: 50 minutes/180 minutes
• Deck size: 21 inches
• Mobility: Self-propelled, automatic pace adjustment
• Mows up to 0.4 acre (17,424 square feet) per charge
• Self-propelled rear wheels
• Motor automatically adjusts output to match mowing conditions
• Lightweight, rust- and corrosion-resistant aluminum deck
• LED headlights allow for ample visibility or nighttime mowing
• Longer recharge time than the competition
• Top mowing speed is too fast for imperfect conditions

Ego Power Z6 42-Inch Zero Turn Riding Mower

Those with larger acreage can now have a battery-powered mower that can actually cut all of their grass on a single charge. The Ego Power riding mower is capable of mowing up to 2 acres per charge, with easy upgrades that can increase runtime to cut more than 3 acres per charge. Plus, it offers many of the same features found on gas-powered zero-turn mowers, such as adjustable lap bars to independently control the rear drive wheels; heavy-duty front swivel casters; a comfortable high back seat with adjustable suspension; a 42-inch deck with 10 height settings from 1.5 to 4.5 inches; and side discharging, mulching, and bagging capabilities.

The electric motor delivers power equivalent to a 22-horsepower (HP) gasoline engine. The Z6 also boasts high-power LED headlights, a battery level indicator, and independently adjustable modes and blade speeds. This mower comes with four 56V 10-Ah lithium batteries, with six available battery slots onboard, and is compatible with any of Ego Power’s other 56V batteries. It also comes with the fastest battery charger in the industry.

With so many features to test, we spent more time with the Z6 than with any of the other battery-powered mowers in this roundup. For our first run, we charged the four 56V 10-Ah batteries that came with the mower and cut as much grass as possible until the batteries ran out. Then we repeated the process with only two batteries, and again with a full “tank” of six batteries.

The mower requires a minimum of 15-Ah to operate, and the charger plugs into the mower to recharge all six batteries at once. Runtime and charge time were as follows: two batteries charged in 1¼ hours and mowed 3/4 acre, four batteries charged in 2 hours and mowed 1¾ acres, and six batteries charged in 3 hours and mowed almost 3 acres (we mowed the entire available area with about 12 percent charge left in the batteries).

We should also mention that the acreage we were mowing included a 1-acre rectangular field and two 1-acre home lots that, in addition to the homes, are approximately 50 percent and 75 percent lawn. The total grass acreage is more like 2¼, with some significant slopes and obstacles to navigate. Since Ego offers an even bigger battery size at 56V and 12-Ah, we estimate that runtime could possibly be stretched to mow up to 4 acres, depending on the condition of the grass and the lay of the land.

The Ego Power Z6’s operation was mostly excellent. Startup was easy, and maneuvering was intuitive. The apparent noise level was extremely quiet and limited to operating the mower deck. The machine travels almost silently when the blades are not running. The lap bars and drive wheels felt somewhat imprecise compared to other zero-turn mowers we’ve used. The machine pulled slightly to the left at full speed on flat ground under an average mowing load. The suspension seat was comfortable, but the relatively small rear tires and light weight of the machine made for a bouncy ride at times. It climbed and maneuvered fairly well on slopes, which is not a strength for most zero-turn mowers.

For most mowing, we kept the machine in “standard” mode and the blades on half power with excellent results. We tested the top blade speed on an area of about 2,000 square feet of overgrown crabgrass that was about 12 inches high, and we had to slow the travel pace significantly to get an acceptable cut in that situation. The Ego Power battery-powered zero-turn mower would make a great choice for any large-acreage owner with lots of grass to maintain.

Product Specs

• Runtime/recharge time: 30 minutes/120 minutes (4 batteries)
• Deck size: 42 inches
• Mobility: Zero-turn riding mower
• Four 56V 10-Ah batteries included, with room for 2 additional batteries
• Onboard Rapid battery-charging system
• 10-position, 42-inch deck allows for ample cutting per pass
• Mows at speeds up to 7 mph/2.6 acres per hour
• Bright LED headlights for low-light mowing
