Direct Replacement Battery

The Estry 4.8V 2100mAh Ni-MH pack is built to the exact specifications of the original Powermaxx Powergrip II battery. It fits Powergrip II, Powergrip2 and Powergrip 2 models and matches part numbers 6.27271, 60005952, 6.27273, 6.27270, 6.31858 and 631858000. Buyers who need a different voltage or a lithium chemistry will not be served by this cell.

2100mAh Capacity and 10.08Wh Energy

The pack delivers 4.8 volts and 2100mAh for a total of 10.08Wh, powering the grip through extended shooting sessions. Runtime scales with the camera’s current draw, so heavy continuous use will deplete the charge faster than occasional triggering. Users who require higher capacity for multi-day events without recharging should look elsewhere.

Protection Circuit and Safety Certifications

An integrated circuit guards against overcharge, over-discharge, over-voltage and short circuits to prolong cycle life. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirming compliance with quality and transport regulations. No charger, cable or firmware is bundled, so buyers must supply their own compatible charging equipment.

Questions about this item

Will this 4.8V 2100mAh pack fit the original Powermaxx Powergrip II battery compartment?

The pack measures 76.24 x 63.89 x 57.07 mm and matches the original Powermaxx Powergrip II form factor, so it slides into the same compartment.

How can I verify the Estry battery is delivering its rated 10.08 Wh after installation?

Charge fully, then run the Powergrip II until shutdown; a healthy pack should provide roughly 2100 mAh at 4.8 V, equating to the rated 10.08 Wh.

Does the box include a charger or only the 307.0 g Ni-MH battery?

Only the replacement battery is supplied; a compatible charger for 4.8 V Ni-MH packs must be purchased separately.
