PORTER-CABLE PC18BLEX 18-Volt Lithium-Ion Cordless EX Battery Pack
The EX Lithium battery offers two times the run time of a PORTER-CABLE® 18V LX pack, but at a weight that of only 1.6 lbs, giving extended performance in a lightweight, compact pack. Lithium-ion batteries hold charge so packs are ready to go even after being stored for extended periods.
