The critical match is the 4.8V voltage combined with the 3000mAh Ni-MH chemistry in the stated 89.6 x 43.1 x 23.38mm form factor. If the original pack differs in voltage, capacity or physical dimensions this unit will not install or perform correctly.

Questions about this item

How can I confirm the 4.8V 3000mAh Estry K50 battery is working correctly after installation?

What comes in the box with the Estry K50 replacement battery and what must I supply myself?

The package contains the Ni-MH 4.8V 3000mAh battery pack only; you reuse the existing charger and pressure-washer housing.

Which version of the Estry K50 battery should I choose for my K50 1.258-101.0 pressure washer?

This single 4.8V 3000mAh Ni-MH pack replaces part ABS-K55 and fits every listed K50, K5.0, K85 and BF9900 model.
