Riding Lawn Mower Batteries

Riding lawn mower batteries provide reliable starting power for lawn tractors, zero-turn mowers, and other gas-powered outdoor equipment. Most riding mowers use U1 or U1R 12V batteries, designed for strong cranking performance and durability in seasonal use.

Choosing the correct lawn mower battery helps ensure reliable starting power, proper cable fit, and safe installation. Our U1 and U1R batteries are built for seasonal outdoor use and vibration resistance.

U1 vs U1R – What’s the Difference?

The only difference between U1 and U1R batteries is the terminal position.  U1 batteries have the positive terminal on the left. U1R batteries have the positive terminal on the right.
