At worst, it will become safety hazard to you, as most improperly used batteries are. At best, a car battery will wear out faster than a lawn mower battery will. Lawn mower batteries must offer a higher resistance to vibration than a car battery can. Why Can’t You Just Use a Car Battery in a Lawn Mower?Įven though battery-powered riding mowers use batteries similar to car batteries, a basic car battery will not do. All the batteries we sell at Batteries Shack are either AGM or gel batteries, which means you should never have to remove any part of the battery to check or refill water levels. Proper charging is the only maintenance you should need. You need a charger that will keep them fresh even during the winter months, when you’re not mowing your grass. Lawnmower batteries that have been left idle tend to crystalize, which means they can’t stay charged. We recommend getting a maintenance charger. One of the easiest ways to help us help you is for you to note the model number of your battery, or to snap a photo of it to show us before you come here to Batteries Shack to buy a new one. Know that the battery voltage isn’t the only determinant of whether it’s right for your lawnmower: Mower batteries also come in several sizes. The casing may also indicate what you need to buy.

You can tell the voltage of the battery by looking at the number of plastic caps on your battery case and multiplying them by two. You should always check your owner’s manual before buying a new battery, and you should check the existing battery in your lawnmower. Unlike a riding mower, a walk-behind mower does not come equipped with an alternator that can keep it charged throughout the mowing cycle. Walk-behind mowers may need batteries of up to 40 volts. If you have a riding mower you’ll probably want a 12-volt battery, similar to a car battery.
