Electric and Cordless Lawn Mower FAQ

How long must a battery charge for a cordless lawn mower?

Charging your electric mower battery for too long can ruin the battery and cause a dangerous acid spill. Some models have an automatic shut-off when the battery is charged. Be sure to follow the manufacturer's guidelines when charging your lawn mower battery. The length of time varies depending on the model.

How long does a cordless lawn mower usually run before it needs recharging?

A full charge should allow you to mow an entire lawn of average size. The average American lawn is about one-fifth of an acre and many electric lawn mower batteries will hold a charge long enough to mow up to a half acre.

Does a lawn mower battery keep over winter? Yes. Simply charge your cordless mower battery and, if possible, remove it for winter storage. Depending on the model, it may be as simple as keeping your battery charger plugged in. Consult your manufacturers instructions. How do I keep the cord out of the mowers way? If you can vacuum, you can mow with an electric mower. Be sure to use an appropriate extension cord that is brightly colored and a bit longer than the longest length you'll need to walk with it. Always be mindful of the cord; one good way to do this is to hold the cord in one hand while gripping the handle and drape the cord over that shoulder as you walk. Never mow over the cord.

Which lawnmower is more eco-friendly: an electric lawnmower or a cordless lawn mower?

Though minimal, both have an environmental impact. Electricity is derived from coal, natural gas, or nuclear energy and batteries contain toxic chemicals that have to be disposed of properly. However, both options are much better for the environment than gas-powered mowers, which emit 87 lbs. of carbon dioxide and 54 lbs. of other pollutants into the air every year, per mower. Electric and cordless mowers emit zero pollution.

Do Electric and Cordless Lawnmowers require a lot of maintenance?

Not at all! Both electric and cordless mowers are virtually maintenance free. No engine means almost no maintenance.

Are Lawnmower batteries easy to attach?

Relatively speaking, yes, lawn mower batteries are easier to deal with than small, gas-powered engines. Always be sure to read and follow the manufacturer's guidelines.

How many hours of use does a lawn mower battery provide before a new one is needed?

While every model is different, lawn mower batteries are rechargeable. Like car batteries, they need proper care and maintenance to ensure a long life. Extremely cold temperatures can drain your battery, so store them in a warm, dry place over winter months. Keep the battery clean and disconnect it when not in use and you will enjoy your cordless lawn mower for years before you need to change the battery.

Which is more efficient: electric or cordless models?

Many variables influence battery efficiency, and 24 volt battery systems typically last 2 to 7 years if well maintained. An electric mower will cost you about $4.00 a year in electricity if you mow your lawn once a week.

What are some basic electric mower maintenance tips?

Unplug your electric mower, or remove the safety key, before attempting to do any kind of maintenance. Use a putty knife to remove grass and debris from the underside of your mower. Check your blades, ensuring that they are on tight and sharp and wipe your mower clean with a damp cloth. If you have a cordless mower, the battery should not be exposed to extreme temperatures.

What should I do with my old gas-powered mower once I replace it with a more eco-friendly mower?

The best thing you can do is to take your old gas mower to a recycling center that accepts mowers. You can also donate it or give it away, but this kind of defeats the purpose of reducing carbon emissions, if that is your goal. You could take the engine out for recycling and make a funky planter out of the mower body. It'll make a statement and is more attractive than the toilet planter.

Can I mow a wet lawn with an electric lawn mower?

No. You risk electric shock if you introduce electricity to water. Never do this.
