It delivers 14.4Wh of energy and includes overcharge, over-discharge, over-voltage and short-circuit protection for safe operation. The pack measures 89.6 x 43.1 x 23.38mm and weighs 296.7g.

Compatibility Check Required

This battery suits owners of the listed Kärcher models who need a direct replacement for part number ABS-K55 and can confirm their device matches the exact model numbers provided. Buyers who cannot verify their model against the supplied list should look at other options, as fitment is not guaranteed for unlisted variants or different voltage requirements.

Voltage and Capacity Decide Fit

The single specification that determines whether this is the correct part is the 4.8V 3000mAh rating; the device must require exactly this voltage and capacity combination. If the original battery shows a different voltage or capacity, this pack will not be suitable regardless of physical dimensions or connector appearance.

Questions about this item

Does the 4.8V Ni-MH pack deliver the full 3000mAh capacity in normal use?

The pack is rated at 4.8V and 3000mAh for 14.4Wh total energy; actual runtime depends on the load drawn by your Karcher model.

Will the 89.6 x 43.1 x 23.38mm case fit the battery compartment of a K50 1.258-106.0?

The replacement matches the original ABS-K55 dimensions of 89.6 x 43.1 x 23.38mm and weighs 296.7g, so it seats in the same bay.

How do I install it without triggering the short-circuit protection?

Power off the device, align the connector polarity exactly as the original pack, press firmly until the latch clicks, then charge fully before first use.
