GE 2-5110 Cordless Phone Compatible Battery 3.7V 500mAh

GE 2-5110 — 3.7V Li-Polymer Replacement Battery (5-2682)

This 3.7V, 500mAh lithium-polymer battery replaces the original pack in the GE 2-5110 cordless phone handset. It fits directly in place of OEM part 5-2682. The cell measures 33.30 × 27.20 × 7.70mm and restores normal handset operation when the original battery no longer holds charge.

• GE 2-5110 handset fit: The 2-5110 handset uses a compact Li-Polymer cell at 3.7V nominal. This replacement matches the OEM voltage and connector orientation, so the handset BMS accepts it without a firmware conflict.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the GE 2-5110 platform. The BMS accepted the pack immediately, reached full charge voltage at 4.2V, and held standby draw within normal range.
• First charge after install: Li-Polymer cells ship at partial charge from storage. Place the handset in the base cradle for a full charge cycle before first use — the GE 2-5110 base charges at a low current rate, so allow the full cycle to complete rather than pulling the handset early.

Talk time shorter than rated after replacing the GE 2-5110 battery

A fresh Li-Polymer cell from storage often delivers below-rated capacity on the first one or two cycles. This is normal — the cell's electrolyte needs a few full charge-discharge cycles to reach its rated 500mAh. Run two or three complete cycles by using the handset until it signals low battery, then returning it to the base for a full charge. Capacity typically stabilises by the third cycle.

GE 2-5110 handset not pairing with base after battery swap

Removing the battery cuts all power to the handset, which can erase the DECT pairing stored in volatile memory. The handset then powers on with no registered base and will not ring or connect calls. Re-register the handset using the base station's paging or registration button — on most GE DECT models this means pressing the base locator button for five seconds until the handset enters pairing mode. Once paired, place the handset in the cradle and confirm the base shows a charging indicator.
