Direct replacement battery

The Estry XB617U is an 8.4V 3000mAh nickel-metal-hydride pack built to match the original Euro Pro specifications. It fits devices that require the XB617U part number and supplies 25.2Wh of energy. The pack measures 108.3 x 49.1 x 50.9mm and weighs 582.0g. Buyers needing a different voltage, capacity or form factor should look elsewhere.

Steady discharge with protection circuits

Integrated overcharge, over-discharge, over-voltage and short-circuit guards regulate current during extended use. The 3000mAh rating reflects sustained delivery rather than a brief peak, and the chemistry maintains stable output across the cycle. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm compliance with safety and transport standards.

Simple drop-in installation

The pack slides into the existing battery bay without tools or soldering. Verify the model number and part number XB617U on the old unit before ordering to avoid mismatch. No firmware updates or calibration steps are required; the protection board manages balancing automatically. Incorrect polarity insertion is the only common error.

Questions about this item

How much heat does the 8.4V 3000mAh Ni-MH pack generate during all-day use?

Ni-MH chemistry runs warm under heavy load but the 25.2Wh rating keeps heat moderate; the built-in over-voltage and short-circuit protection prevents thermal runaway.

What existing charger connector must I already own to recharge this XB617U pack?

The pack uses the original Euro Pro XB617U connector, so you need the matching Euro Pro charger that came with the device.

Will this 108.3 x 49.1 x 50.9mm replacement fit the same battery bay as my original XB617U cell?

Yes, the dimensions and 8.4V 3000mAh specification match the original XB617U pack exactly for a direct fit.
