Numatic NX300 Battery

Cordless shifts stand or fall on battery planning. This NX300 36V 300Wh pack powers the Numatic cordless NX machine range, so shifts run on swaps rather than sockets.

Use it across machines including the 244NX compact scrubber, the TTB1840NX and the WBV370NX wet vacuum for regular cleaning rounds. Seat a charged pack, work the allocated zone, then swap to a fresh pack at the trolley instead of hunting a socket. On the 244NX the platform gives up to 80 minutes, and on the TTB1840NX one pack gives 60 minutes with a second stretching the shift to 2 hours. Rotate packs through the dock so one always charges while another works.

The pack is rated 36V with 300Wh capacity in the NX300 format, the shared platform across the cordless NX range. Shared fit is the value, since one battery type covers scrubbers and vacuums together. Charge behaviour follows the machine sheets, with 80 percent in about an hour on fast configurations and full charge in around 2 hours.

Number each pack and rotate them in order so wear spreads evenly across the set. Store on the dock or a dry shelf at room temperature, never on a wet plant room floor. Retire packs that no longer hold a useful shift and recycle through battery channels, because a tired pack silently shortens every round it powers.
