Compatible Uniden Walkie-Talkie Power

This two-pack of Kastar BT-1028 batteries supplies 3.6 V 1000 mAh Ni-MH energy for Uniden GMR3040-3CK GMR3040-2CK and GMR2638-2CK two-way radios. They replace the original BT-1028 58037235E cells so users can keep a spare set charged for extended outdoor or professional use.

Chemistry Voltage Capacity Match

Each cell delivers 3.6 volts and 1000 milliampere-hours in a Ni-MH chemistry that fits the radio's charging circuit. Using a different voltage or chemistry would prevent correct charging and could damage the handset.

Low Self-Discharge Thermal Stability

The embedded seal structure reduces self-discharge so the pack holds its charge during storage. Ni-MH construction avoids the thermal runaway risk of lithium chemistries and the steel shell contains pressure if the cell is overcharged.

Questions about this item

How long will the 1000 mAh rating last in a real walkie-talkie?

The 1000 mAh capacity at 3.6 V gives 3.6 Wh of energy, so a radio drawing 100 mA would run for roughly ten hours before needing a recharge.

What charging standard does the Ni-MH chemistry require?

These Ni-MH cells use a standard 3.6 V charge voltage and accept typical constant-current chargers designed for nickel-metal-hydride packs.

Will the 44.5 x 30.5 x 10.16 mm pack fit my Uniden GMR3040 handset?

Yes, the pack matches the original BT-1028 dimensions of 44.5 mm by 30.5 mm by 10.16 mm and is listed as compatible with the GMR3040 series.
