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.
