What It Is

This is a 12.8V 12Ah lithium lawn mower battery (480 CCA) designed to replace lead-acid batteries in ride-on mowers and garden tractors. It delivers reliable starting power for brands like John Deere, Cub Cadet, Craftsman, and Troy-Bilt.

Fitment & Compatibility

Before buying, verify your mower’s battery tray dimensions: this battery measures roughly 7.7 x 5.1 x 6.1 inches (U1R group size). It fits any mower that uses a standard U1R battery with positive terminal on the right (when facing the battery terminals). Check your owner’s manual or existing battery label for “U1R” and “Positive Right” markings. This is an aftermarket replacement—no OEM part number cross-reference needed, but confirm your mower’s charging system is compatible with lithium (most 12V systems work, but some older regulators may overcharge). If your mower has a voltage regulator output above 14.6V, you may need a lithium-specific charger.

Key Things to Know

• Installation: Direct swap—remove old battery, connect red to positive, black to negative. No acid or venting concerns.
• Weight: ~3.5 lbs (vs. 12+ lbs for lead-acid), which can reduce vibration and make handling easier.
• Cold weather: Lithium performs better than lead-acid in cold starts, but avoid charging below 32°F.
• CCA vs. Ah: 480 CCA is enough for most single-cylinder engines; 12Ah capacity supports moderate runtime for electric-start models. Not for heavy electric deck lift or accessory loads.

Should You Buy It

Buy this if you want a lighter, maintenance-free lithium battery that starts reliably in cold weather and fits standard U1R tractors. Skip it if your mower has a high-output charging system (above 14.6V) or if you need deep-cycle capacity for electric mowers or heavy accessory use.
