WEIZE Lawn Garden AGM Battery, 12V 300CCA BCI Group U1 SLA Starting Battery for Lawn, Tractors and Mowers, Compatible with John Deere, Toro, Cub Cadet, and Craftsman

What It Is

The WEIZE Lawn Garden AGM Battery is a 12V, 300 CCA sealed lead-acid battery in the BCI Group U1 size, designed to start lawn tractors, zero-turn mowers, and garden tractors from brands like John Deere, Toro, Cub Cadet, and Craftsman. It uses Absorbent Glass Mat (AGM) technology for vibration resistance and maintenance-free operation.

Fitment & Compatibility

Before buying, check three things:

• BCI Group Size: Must be Group U1 (dimensions approx. 7.7" L x 5.1" W x 6.1" H). Measure your existing battery tray to confirm it fits.
• Terminal Layout: This battery has left positive, right negative (standard U1 layout). Verify your mower’s cable orientation matches (most John Deere, Cub Cadet, and Toro models do).
• CCA Rating: 300 CCA is sufficient for most single-cylinder and small twin-cylinder engines (up to ~25 hp). For larger engines or cold climates, consider a higher CCA battery.
• OEM vs Aftermarket: Works as a direct replacement for OEM batteries like John Deere TY24430, Cub Cadet 725-04576, and Toro 120-3106. Not compatible with electric mowers or deep-cycle applications.

Key Things to Know

• Installation: Simple swap—remove old battery, clean terminals, connect red to positive (+), black to negative (-). No electrolyte filling or charging needed out of the box.
• Quality: AGM design resists leaks and handles vibration better than flooded batteries. 300 CCA is adequate for warm-weather starting; may struggle in sub-freezing temps with larger engines.
• Gotchas: Check that your mower’s charging system outputs 13.5-14.5V; if it overcharges, it can damage AGM batteries. Also, ensure the battery hold-down bracket fits the U1 case width (some older mowers use a slightly different shape).
• Lifespan: Expect 3-5 years with proper care. Keep terminals clean and store in a dry place during off-season.

Should You Buy It

Buy this if you need a reliable, maintenance-free replacement for a standard Group U1 lawn tractor battery at a fair price. It’s a solid choice for most John Deere, Cub Cadet, Toro, and Craftsman riders with engines under 25 hp. Skip it if your mower requires a larger group size (like U1R) or higher CCA for cold-weather cranking.
