BLACK+DECKER 6v/12v Battery Maintainer/Trickle Charger BM3B

BLACK+DECKER BM3B 6V/12V battery maintainer and trickle charger — automatic maintenance charging for cars, trucks, motorcycles, boats, and lawn equipment. Prevents battery drain during storage.

The BLACK+DECKER BM3B is an automatic battery maintainer and trickle charger that keeps 6V and 12V lead-acid batteries fully charged during storage without overcharging. Connect it and leave it — the automatic maintenance mode monitors battery voltage and applies a trickle charge only when needed. Suitable for cars, trucks, motorcycles, ATVs, boats, RVs, and lawn equipment.

Key specs:

Why it works:

Lead-acid batteries self-discharge during storage — a battery left in a vehicle or equipment over winter can discharge to the point where it won't accept a charge and needs replacement. A maintainer prevents this by keeping the battery at full charge without the overcharging risk of a standard charger left connected. The BM3B's automatic mode makes it safe to leave connected indefinitely.

Ideal for: Vehicle owners, boaters, and outdoor equipment users who store vehicles or equipment seasonally and want to prevent battery drain and replacement costs.
