Product information

The high capacity Flex AP 18.0/5.0 Ah pack, holding twice the energy of the 2.5 Ah battery for roughly twice the runtime from a single charge. Worth having on any job where stopping to swap packs breaks the work, such as a full vehicle correction or a long vacuuming session.

The same electronic management system found across the Flex range monitors every cell for overcharge, deep discharge and heat, and a four stage LED gauge on the pack reports remaining charge on demand.

Fits the full Flex 18V cordless range including the BW 18.0-EC blower and the VC 6 L MC cordless vacuum. Charge with the CA 10.8/18.0 rapid charger.
