A New Generation of Battery Chargers
Battery Sentinel Battery Chargers
The Most Advanced, Fully Automatic Chargers Ever!

Looking for a Float Battery Charger or a Trickle Battery Charger? Our Battery Sentinel maintainer chargers perform those functions and more.

All Battery Sentinel chargers are 100% automatic and self regulating. They will never overcharge or damage any battery regardless of battery size or type and regardless which Battery Sentinel is connected to it. So it's completely safe to choose a Battery Sentinel charger with a higher amp output rating. The advantage of choosing a charger with a higher amp output rating is that when it is used as a "regular battery charger", it will re-charge a dead battery faster, due to its higher amperage output. Once the battery is fully charged, all Battery Sentinels function exactly the same in the maintenance mode.
