How does AGM construction benefit off-road and seasonal use?

AGM batteries use glass mat separators to hold electrolyte, making them leak-resistant and more robust under vibration compared with conventional flooded cells. They tolerate intermittent use and storage without needing maintenance, reducing hassle for riders who trail-ride, hunt, or store their ATV seasonally.

• Sealed, maintenance-free design — no watering required
• Improved vibration resistance for rugged terrains
• Lower self-discharge rate for better seasonal storage

What installation and charging precautions should I follow?

Install the battery with the negative cable disconnected first and tighten connections securely to avoid arcing. Use a charger compatible with AGM chemistry and follow the charger manufacturer’s recommendations to maximize life; avoid excessive overcharging and deep discharges.

• Disconnect ground cable before positive during install/removal
• Use an AGM-capable smart charger for charging and storage
• Avoid prolonged deep discharge to extend service life
