Caltric Agm Battery Compatible with John Deere Lx172 / Lx173 / Lx176 / Lx178 Lawn Tractor

What It Is

This is a sealed absorbed glass mat (AGM) battery designed to start and power John Deere LX series lawn tractors. It replaces the OEM battery and provides maintenance-free operation for gas-powered mowers and garden tractors needing a 12V, 340 CCA (cold cranking amps) power source.

Fitment & Compatibility

Before buying, confirm your tractor model matches the listed LX172, LX173, LX176, or LX178. Check your existing battery’s physical dimensions: this Caltric battery measures approximately 7.7 x 5.2 x 6.1 inches (L x W x H). Verify your battery tray can accommodate those dimensions and that the terminal posts are in the same orientation (positive on left, negative on right when facing the battery). This battery is a direct replacement for OEM John Deere part numbers AM101249, AM101250, and AM101251. It does not fit LX series tractors with a different battery tray or those requiring a larger group size (e.g., U1R). Measure your current battery and compare to avoid return hassles.

Key Things to Know

• Quality: AGM construction means no watering, no acid spills, and better vibration resistance than flooded lead-acid batteries. 340 CCA is sufficient for most LX series engines in moderate climates.
• Installation: Simple DIY swap—disconnect negative terminal first, then positive, remove hold-down, install new battery, reconnect positive then negative. No special tools required.
• Gotcha: This battery is shipped dry-charged and may arrive with a low charge. Charge it fully (12.6V+) before first use or the mower may crank slowly. Use a compatible AGM charger, not a standard car charger.
• Warranty: Caltric offers a 1-year warranty, but verify return policy with your seller—some online retailers have restocking fees for batteries.

Should You Buy It

If you own a John Deere LX172, LX173, LX176, or LX178 and want a drop-in, maintenance-free battery at a lower price than OEM, this is a solid choice. It’s ideal for DIYers who can charge it before first use and don’t need dealer support. Avoid if you require a higher CCA rating for extreme cold starts or need a battery with a longer warranty period.
