Autocessking Lawn Garden AGM Battery Group 1 (U1-350CCA) Rechargeable SLA Starting Battery for Lawn, Tractors and Mowers, Compatible with John Deere, Toro, Cub Cadet, and Craftsman Mower

What It Is

The Autocessking U1-350CCA is a sealed lead-acid (AGM) battery designed to start lawn tractors, zero-turn mowers, and riding mowers. It’s a drop-in replacement for Group 1 (U1) batteries used in many John Deere, Toro, Cub Cadet, and Craftsman models.

Fitment & Compatibility

Check these before buying:

• Group size: Must be Group 1 (U1). This battery is 7.7" L x 5.1" W x 6.2" H. Measure your old battery’s tray to confirm fit.
• CCA rating: 350 CCA (cold cranking amps) is standard for most single-cylinder and small V-twin mower engines. If your mower requires 400+ CCA, this may not be enough.
• Terminal orientation: It has SAE automotive posts (positive left, negative right when facing terminals). Verify your cables reach and the polarity matches.
• OEM vs aftermarket: It’s an aftermarket battery. Works as a direct replacement for OEM part numbers like John Deere AM131239, Toro 121-4314, Cub Cadet 925-1709A, and Craftsman 33522.
• Brand-specific checks: For John Deere 100/300 series, Toro TimeCutter/Zero-Turn, Cub Cadet XT1/XT2, and Craftsman LT1000/GT5000—fits without mods. For older models, verify tray dimensions.

Key Things to Know

• Quality: AGM design means no maintenance, no acid spills, and vibration resistance. 350 CCA is adequate for moderate climates; may struggle in sub-freezing starts.
• Installation difficulty: Very easy. Disconnect negative first, remove hold-down, swap terminals. Torque to 5-8 ft-lbs.
• Gotcha: This battery is not for deep-cycle use (electric mowers or trolling motors). It’s only for starting—don’t drain it below 50%.
• Lifespan: Expect 3-5 years with proper charging. If your mower sits for months, use a maintainer to prevent sulfation.

Should You Buy It

Buy this if you need a reliable, no-fuss replacement for a Group 1 mower battery and your engine is a standard 12-20hp gas engine. It’s a strong value for the price, but skip it if your mower requires a higher CCA rating or a deep-cycle battery for electric accessories.
