Description
Replacement Rechargeable Lithium Ion Batteries for Power Tools, Lawn Mowers, and Chainsaws
-
Never wait on a dead pack: replacement batteries for power tools get you back to work fast
-
Power that outlasts the job: rechargeable lithium batteries hold a steady charge through long mowing or trimming runs
-
Steady power under load: the lithium ion battery's microchip guards against overcharge, overcurrent, and overheating
-
One battery, every tool in the shed: the same battery for chainsaw work also drives your mower, sprayer, or tiller
-
Ready the moment you grab it: this long lasting battery pack is plug-and-play, ready in about a second
Your mower dies halfway through the yard, or the trimmer finally won't hold a charge, and the whole tool goes back on the shelf until a new pack shows up. This lithium ion battery drops into a Makita-compatible interface, so the same pack you charge tonight can run your lawn mower, sprayer, tiller, or long-reach chainsaw tomorrow. An integrated microchip watches the cell the whole time it's on the charger, guarding against overcharging and self-discharge, so it's safe to leave charging overnight.
