Compatible Walkie-Talkie Battery

The Estry 777 is a nickel-metal hydride replacement pack built for Midland two-way radios including the 777 Pro, GXT-1050, GXT-661, GXT600VP1, G9 Pro, LXT305, GXT550VP1, GXT1030VP4 and GXT400VP1. It matches the original form factor and connector so users can swap it without tools or adapters.

700mAh Capacity And Runtime

Rated at 6.0 volts and 700 milliampere-hours the pack stores 4.2 watt-hours of energy, providing a full day of typical voice traffic on a single charge. Heavy transmit duty or cold weather will drain it faster, so operators planning extended shifts should carry a spare.

Thermal Behaviour And Protection

Built-in circuitry guards against overcharge, over-discharge, over-voltage and short circuits, keeping cell temperature stable during normal charge cycles. The pack meets ISO9001, RoHS, CE, UN38.3 and MSDS certifications, indicating compliant materials and safe transport characteristics.

Questions about this item

Will the 6.0V 700mAh pack fit my existing GXT-661 walkie-talkie?

Yes, the Estry 777 is listed as a direct replacement for the GXT-661 and other compatible Midland models using part numbers PB-ATL or BATT-5R.

How can I confirm the 4.2Wh battery is charging correctly after installation?

The pack includes overcharge and over-discharge protection; the radio’s charge indicator should show normal cycling and the unit will power on without voltage warnings.

Does the box contain only the 92.0g Ni-MH cell or also a charger?

The package supplies the 6.0V 700mAh battery pack only; a compatible charger for your specific Midland radio must be sourced separately.
