Direct replacement for Ohaus scales

The Estry 7.2 V 3000 mAh Ni-MH pack replaces the original GP300SCH6S6Z and 80500729 cells in Defender 5000, Defender 7000, T51, T51P, T51XW and T71 bench scales. It matches the factory voltage and capacity so the scale powers on without recalibration.

Worth the swap when runtime drops

If the original pack no longer holds a full shift or the scale shuts down during weighing, this 21.6 Wh unit restores the specified run time. The jump is worthwhile when the old battery shows reduced capacity or fails the built-in self-test.

Steady output under continuous use

Overcharge, over-discharge, over-voltage and short-circuit protection circuits keep the voltage stable during long weighing sessions. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm the pack meets safety standards for sustained industrial operation.

Questions about this item

What are the physical dimensions of the Estry 7.2 V 3000 mAh Ni-MH battery for the Ohaus Defender 5000 bench scale?

The battery measures 131.45 mm in length, 44.76 mm in width, and 22.9 mm in thickness, weighing 483.4 g to fit the Defender 5000 and 7000 series.

How is the replacement battery installed in the Ohaus T71 scale, and which step is commonly missed?

Remove the battery compartment cover, disconnect the old pack connector, connect the new GP300SCH6S6Z pack ensuring the plug seats fully, then refit the cover; the step often missed is verifying the connector clicks securely into place.

When will the Ni-MH pack in the Ohaus Defender 7000 need replacement, and what part number should be reordered?

Replace the pack when run-time drops noticeably or the scale fails to hold a charge; reorder using part number 80500729 or GP300SCH6S6Z for the Defender 5000, T51, T51XW and T71 models.
