Compatible Karcher Power-Tool Battery

This 25.2 V lithium-ion pack replaces the original BV 5/1 Bp and T 9/1 Bp cells for Karcher EF426 and BV 5/1 Bp T 9/1 Bp tools. It delivers 4.5 Ah capacity using Samsung cells rated at 113.40 Wh. The black housing measures 143.00 x 86.50 x 75.87 mm and is supplied as a single unit.

Upgrade From Worn Original Cells

The jump is worth it when your existing pack no longer holds a full charge or shows reduced run-time on the job. A fresh 4500 mAh cell restores the tool to its factory energy rating of 113.40 Wh without modifying the charger or the tool electronics.

Check Tool Model And Voltage Before Ordering

Verify that your device is listed as EF426, BV 5/1 Bp or T 9/1 Bp and that the nameplate reads 25.2 V. Confirm the physical cavity can accept a pack of 143.00 x 86.50 x 75.87 mm. This battery is not for users who need a different voltage platform or a higher amp-hour rating than 4.5 Ah.

Questions about this item

Will the 143.00 x 86.50 x 75.87 mm pack fit my KARCHER EF426 tool?

The battery measures 143.00 x 86.50 x 75.87 mm and is built for the EF426 and BV 5/1 Bp T 9/1 Bp models, so it slots straight into the tool's battery bay.

How do I install the 25.2 V 4500 mAh Li-ion pack without damaging the contacts?

Align the pack with the tool's guide rails, push until the latch clicks, and avoid forcing it at an angle which can bend the connector pins.

When should I replace the Samsung-cell 4.5 Ah battery?

Replace the pack when run-time drops noticeably or the tool cuts out under load, indicating the 113.40 Wh cells can no longer hold sufficient charge.
