Attwood Fully-Automatic Battery Maintenance Charger

This Attwood Battery Maintenance Charger is a fully automatic on-board charger built to maintain 12-volt batteries at a steady 1.5 amp maintenance charge. It's designed to stay connected long-term rather than for a quick top-off.

It's water resistant with built-in safety features, including short circuit protection and reverse polarity protection, guarding against the most common wiring mistakes during installation. LED status indicators show charge state at a glance.

This single-bank unit handles one battery at a time. It's a straightforward fit for a boat that needs to keep its battery topped off between trips without a full multi-bank charging system. Shop more battery management systems.
