Battery Tender Plus
The Battery Tender Plus constantly monitors the battery without the damaging effects of trickle chargers; a trickle charger will eventually boil dry or overcharge a battery.
Battery Tender Plus' voltage output compensates for temperature changes, providing additional protection.
Initial charge brings battery to full charge at approximately 14.4V.
After full charge is reached, converts to float charger and monitors battery at 13.2V.
Although a constant charge is being applied to the battery, there is little or no current (approximately 10mA).
Periodic maintenance is recommended, but Battery Tender can monitor a battery for years without the fear of boiling or destroying the battery.
12V Battery Tender Plus has fused quick-disconnect rings with a weather cover.
