The first thing you need to know when shopping for a new battery is your mower’s voltage requirement. Most riding mowers take a 12 volt battery, although some smaller mowers rely on a 6 volt battery. If you’re unsure what type of battery your mower requires, you can check the voltage of your old battery, or look up the information in your owner’s manual or on the manufacturer’s website.

In order to make it easier to find the right battery, the Battery Council International (BCI) has broken batteries down into a number of different group battery sizes. Most lawn mower batteries fall into the Group U1 format.

Another thing you need to know is your battery’s terminal type and position. This information will also appear in the group battery sizing standards. For instance, the “U1” group size has two different options: U1L and U1R. Group U1L batteries have the positive terminal located near the top left corner of the battery, while a Group U1R battery has the positive terminal positioned near the top right corner. When replacing your lawn mower battery, be sure to identify which type of terminal positioning your mower requires.

A lawn mower battery will have a much lower number of CCAs than a typical auto battery. For most mowers you’ll want a battery with a minimum rating of 145 CCA. Your owner’s manual or the manufacturer’s website will supply you with the correct CCA specifications for your mower.
