Users Needing Exact Compatibility

This unit suits owners of the 8800 model who must replace part numbers GP-S10-374192-010H, CP-BATT-8821 or 74-102376-01. Buyers with different devices or alternative part numbers should look elsewhere. The pack contains only one cell, so anyone requiring multiples must order additional units.

Capacity Determines Runtime

The 2400mAh rating sets the total energy available at 9.12Wh and directly controls how long the device runs between charges. Verify that this capacity matches the original specification before purchasing.

Questions about this item

How do I install the Estry 8800 battery and what step is often missed?

Power off the device, remove the old pack, align the 101.96 x 41.9 x 4.2 mm replacement, connect the cable fully, and verify the 3.8 V label matches before closing the case.

What maintenance or replacement will this 2400mAh lithium pack need later?

Expect gradual capacity loss after several hundred charge cycles; replace the pack when run-time drops below your needs, typically after two to three years of daily use.

What limit appears first under sustained load with the 9.12 Wh cell?

The built-in protection circuit will cut output if current exceeds safe thresholds, so prolonged high-drain use triggers an early shutdown before the cell overheats.
