GE 700 Cordless Phone Replacement Battery 3.6V 600mAh

GE 700 Cordless Phone — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 600mAh Ni-MH rechargeable battery for the GE 700 cordless phone handset. It replaces the original pack when the handset no longer holds a charge or loses power mid-call. Voltage and chemistry match the base station charging circuit exactly.

• GE 700 handset fit: The GE 700 base station delivers a fixed trickle charge tuned for a 3.6V Ni-MH cell. Swapping to a different voltage or chemistry causes the charging circuit to over- or under-charge — this battery matches that spec directly.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the GE 700 platform. The BMS accepted the cell without error, and the handset powered on and registered to the base on the first attempt.
• First-charge protocol for NiMH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before use. NiMH cells shipped in storage state need a slow initial charge to reach rated capacity — skipping this cuts talk time short for the first several cycles.

Talk time shorter than the original battery after replacement

NiMH cells leave storage partially discharged, and the first charge cycle rarely brings them to full rated capacity. The GE 700 base delivers a slow trickle charge — it takes 3 to 5 full cycles before the cell reaches 600mAh. Each cycle should be a full charge followed by normal use until the handset shows low battery, then a return to the base for a complete recharge.

Base station charge light not activating with new battery installed

If the GE 700 base shows no charge indicator after a battery swap, the cell voltage has likely dropped below the base's acceptance threshold during storage — typically below 3.0V. The base detects this as a fault and won't initiate the charge cycle. Remove the battery, let it sit at room temperature for 10 minutes, then reseat it firmly in the handset and return it to the base. If the light still does not activate, check that the handset contacts are clean and making full contact with the base cradle pins.
