Jimmy B0ZJ1760002R battery for HW9 Pro

Jimmy B0ZJ1760002R — wet & dry floor washer battery for the HW9 Pro. A wet floor washer works its battery harder than a dry vacuum does: the roll spins, water is pumped and the motor heats up all at once. Hence the noticeable drop in runtime after a couple of years — the pack changes by hand and the machine gets its original range back without a service visit.
