Lawn Mower AGM Battery Group U1 12V 24ah 200CCA Rechargeable SLA Starting Garden Batteries for Tractors, Lawn and Riding Mowers, Compatible with Craftsman, Cub Cadet, and Toro

What It Is

This is a sealed, maintenance-free AGM (Absorbent Glass Mat) battery designed to start riding lawn mowers, garden tractors, and zero-turn mowers. It delivers 12 volts, 24 amp-hours (Ah), and 200 cold cranking amps (CCA) – enough for most single-cylinder and small V-twin engines.

Fitment & Compatibility

• Group Size U1 – physically measures roughly 7.7" L x 5.1" W x 6.2" H. Measure your battery tray and hold-down bracket to confirm clearance.
• Terminal Layout – check terminal position (positive left/negative right or reversed). This battery typically uses standard SAE posts, but verify orientation matches your cables.
• Brand Compatibility – listed for Craftsman, Cub Cadet, and Toro, but fits any mower requiring a Group U1 battery with these specs. Not for zero-turn mowers needing larger batteries (Group U1R or U1L variants).
• OEM vs Aftermarket – this is an aftermarket alternative to OEM batteries (e.g., Cub Cadet OEM part 725-04558). Verify your original battery’s CCA rating – 200 CCA is standard for 15–25 HP engines.
• Check Before Buying – confirm your mower’s battery tray dimensions, terminal type (post vs. screw), and polarity. Also measure the hold-down bracket height to ensure clearance for the battery’s height.

Key Things to Know

• AGM vs Flooded – AGM is spill-proof, vibration-resistant, and charges faster than traditional flooded batteries. No water refill needed. However, it requires a charger with AGM mode or a low-amp trickle charger (1–2 amps) for storage.
• Installation Difficulty – easy (swap and reconnect). Disconnect negative first, then positive. Tighten terminals to 60–80 in-lbs. Use anti-corrosion washers or spray.
• Common Gotchas – if your mower has a battery warmer or tray with tight sides, this battery’s case may be slightly taller or wider than some OEM units. Double-check height with the hold-down bar. Also, if your old battery was 230–250 CCA, this 200 CCA may struggle in very cold starts (below 20°F).
• Shelf Life – AGMs self-discharge slower than flooded (about 2–3% per month at 70°F). If storing over winter, charge it fully and disconnect or use a maintainer.

Should You Buy It

Yes, if you need a reliable, no-maintenance replacement for a standard Group U1 battery in a riding mower with a 15–25 HP engine. It’s a good value for the price, but skip it if your mower requires higher CCA (e.g., for cold-weather starting) or if your battery tray is tight on height.
