MARXON U1 12v 330CCA Riding Lawn Mower Battery, Garden Tractors Battery Maintenance Free AGM Batteries Compatible with Troy-Bilt John Deere Toro Cub Cadet Craftsman Ariens Poulan Pro Massey Ferguson

What It Is

The MARXON U1 12v 330CCA AGM battery is a maintenance-free replacement battery designed for riding lawn mowers, garden tractors, and zero-turn mowers. It delivers 330 cold cranking amps (CCA) for reliable starts in cold weather and uses AGM (Absorbed Glass Mat) technology, so you never need to add water.

Fitment & Compatibility

Before buying, confirm your mower requires a U1 group size battery. Measure your battery tray: U1 dimensions are roughly 7.7" L x 5.1" W x 6.2" H. This battery fits most Troy-Bilt, John Deere, Toro, Cub Cadet, Craftsman, Ariens, Poulan Pro, and Massey Ferguson models with U1 slots, but always check your owner’s manual or original battery label. It’s an aftermarket replacement, not OEM—verify terminal orientation (positive left or right) matches your cables. Does not fit lawn tractors requiring a larger group size (e.g., U1R or U1L variants).

Key Things to Know

• No maintenance required: AGM design is sealed and spill-proof; no electrolyte checking or topping off.
• Installation is straightforward: Remove old battery, clean terminals, connect positive then negative, secure hold-down. Takes about 10 minutes.
• 330 CCA is adequate for most residential riding mowers but may struggle in extreme cold (below 0°F) or for high-compression engines—check your engine’s CCA requirement.
• Terminal type: Standard SAE automotive posts (not threaded studs). Ensure your cable clamps fit snugly.

Should You Buy It

Buy this battery if you want a drop-in, maintenance-free replacement for a standard U1 riding mower and don’t need extreme cold-weather cranking power. It’s a reliable, well-reviewed option for most Troy-Bilt, John Deere, Toro, and Cub Cadet models at a fair price. Skip it if your tractor requires a higher CCA rating or a different group size.
