A riding lawn mower will help you keep up with a large lawn. Even if you take good care of your mower, the battery will die. Buying a lawnmower battery may seem like a tough task, but it isn't. You can find the best riding lawn mower batteries for your needs by knowing a few facts.

Things to consider when choosing riding lawn mower batteries

Size and voltage

Riding lawn mower batteries are mostly the same size and voltage. Replacing a 12-volt battery usually requires a 7- to 8-inch battery (7-to-7-inch battery fits snugly in the compartment). Otherwise, your lawn mower's battery may not fit if your present battery's dimensions are vastly different. See different types of riding mower batteries

Terminal position

The terminals are where your lawn mower's wires connect to the battery. Riding lawn mowers have two possible terminal positions. The most common battery has the positive terminal in the left top corner. A U1L battery. Rarely, U1R batteries have the positive terminal at the top right corner. If the positive terminal is not located correctly on the battery, the wires may not be long enough to reach the correct terminal.


Cold cranking amps

Cold cranking amps (CCA) show how much power a battery can provide for 30 seconds at 0o F. If you buy a battery with lower CCAs than suggested, it may not start your riding lawn mower. A battery with too many CCAs won't hurt the engine, but it won't help you either. To get the best value, match the battery's CCAs to your mower's needs.

Rugged construction

A riding lawn mower battery that cracks is useless. Look for a model that is durable, shock-resistant, and vibration-resistant.


A costlier riding lawn mower battery has greater cold cranking amps. A 150 CCA will cost roughly $40. For additional start-up power and a more lasting design, expect to pay roughly $75. Avoid models that cost a lot more because they may not be the best value.


Q. Is it hard to install a riding lawn mower battery.

A. Definitely not. Placing the lawnmower battery in its assigned spot, potentially clamping it down (though not all riding mowers require this step), and connecting the wires to the correct terminals (red to positive, black to negative).

Q. How should a riding lawn mower battery be stored?

A. Remove the battery from the riding lawn mower and leave it on a trickle charger for an hour or two each week until mowing season returns.
