How to Charge an 18-Volt Lithium-Ion Makita Battery

Updated February 21, 2017

Makita Cordless power drills use rechargeable lithium-ion battery packs for power. When the drill begins to lose power, the battery pack should be recharged. In order to complete this process, the battery pack must be removed from the drill. Never attempt to recharge the battery pack while it is still connected to the drill, or you can cause the unit to short out or cause an electrical fire. Makita battery packs should only be recharged with Makita charging units. Using any other type of charger will void your manufacturer's warranty.

Turn off the Makita drill. Never attempt to remove the battery pack while the drill is turned on.

Press the button on the battery pack to unlock the battery pack from the drill's handle. The battery pack is connected to the bottom of the handle. Once unlocked, slide the battery pack outward for removal.

Slide the battery pack into the battery charger. When the battery pack no long slides back, it is fully inserted.

Plug the Makita battery charger into an appropriate power source. If you are using an electrical charger, plug the charger into an electrical socket. If you are using a car charger, plug the cord into an automobile cigarette lighter socket. Once connected to a power source, the charging light will turn red, indicating the battery is charging.

Unplug the Makita charger from the power source when the indicator light changes from red to green. Makita batteries and battery chargers use smart chips which prevent the batteries from overcharging. Once the unit is unplugged from the power source, slide the battery out of the battery charger and reinsert it into the Makita cordless drill.
