GE TL-2613 Cordless Phone Replacement Battery 3.6V 700mAh

GE TL-2613 Series — 3.6V Ni-MH Replacement Battery

This 3.6V, 700mAh Ni-MH battery replaces the rechargeable pack in GE cordless phone handsets. It fits the TL-2613, TL26413, TL96413, and 86413, along with additional models in the same family. The voltage and cell configuration match the original spec exactly.

• TL-2613 family compatibility: These models share the same 3.6V three-cell Ni-MH pack with identical connector orientation and physical footprint. The base station charging circuit expects this voltage range, so swapping within this family works without modification.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a TL-series handset. The base station accepted the battery without a charging fault, and the BMS held voltage within the expected range across multiple cycles.
• First-charge requirement for Ni-MH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells shipped from storage are partially discharged. Skipping this step limits initial capacity and throws off the base station's charge termination timing.

Talk time shorter than the original battery after replacement

Ni-MH cells don't reach rated capacity on the first cycle. The electrochemical pathways in a fresh cell need three to five full charge-discharge cycles before the pack delivers its full 700mAh. If talk time feels short immediately after swapping the battery, that's expected behaviour — not a fault. Run the handset to low battery, return it to the base for a full charge, and repeat for several cycles before drawing conclusions.

Base station showing no charge or error light after battery swap

GE base stations use a voltage threshold to confirm a valid battery is seated before starting the charge cycle. A Ni-MH pack that has been in storage can drop below 3.0V, which some bases reject entirely. Remove the handset, wait 30 seconds, and reseat it firmly — full contact on the charging pins sometimes resets the detection. If the error persists, the pack voltage is likely too low; charge the handset using a compatible external charger briefly to bring it above 3.2V, then return it to the base.
