Reliable Power for Your Toughest Tasks

The AGM U1L-350 Fulbat Replacement Starter Battery is engineered to deliver dependable starting power for lawn mowers, garden tractors, and powersports equipment. With 350 Cold Cranking Amps (CCA), this battery provides the punch needed to turn over engines in any weather, ensuring your equipment is ready to work when you are.

Advanced AGM Maintenance-Free Technology

Forget the hassle of checking water levels or dealing with acid leaks. This Fulbat battery utilizes Absorbed Glass Mat (AGM) technology, which traps the electrolyte in fiberglass separators. The result? A completely spill-proof, vibration-resistant battery that requires zero maintenance. Whether you're navigating bumpy terrain or storing equipment for the winter, the U1-350AGM is built to endure.

Maximize Battery Life with Smart Charging

To keep your battery in peak condition during the off-season, we highly recommend pairing it with the Battery Tender 4A 6V/12V Selectable Charger. Unlike standard trickle chargers, it uses a 4-step charging process to maintain optimal voltage without overcharging, significantly extending the lifespan of your investment.
