This Advanced Battery Charging System can help you extend the life of your battery.

Simply plug the 4-amp charger into a standard 115-VAC wall outlet and connect the alligator clips to your terminals under the hood.

The device's onboard microchip monitors and regulates the charge- virtually eliminating sulfating.

This product is now switchable between AGM (Lead Acid/Standard) and Lithium-Ion batteries (as found in the F80 M3 and F82/F83 M4).
