Gte 3000 Cordless Phone Replacement Battery 3.6V 170mAh

Gte 3000 / 3100 / 3200 / 5200 Series — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 170mAh Ni-MH replacement battery for the Gte 3000, 3100, 3200, and 5200 cordless phone handsets. It fits directly into the handset battery compartment and restores the handset to cordless operation when the original pack no longer holds a charge. Voltage and capacity match the original factory specification.

• 3000 / 3100 / 3200 / 5200 handset compatibility: These models share the same 3.6V three-cell NiMH pack format, battery compartment dimensions, and connector orientation. One replacement covers the full range without modification.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a NiMH-compatible test rig. The cells accepted a full charge without thermal event, and the voltage held steady at 3.6V nominal across the discharge curve at low handset draw rates.
• First charge on a NiMH cordless handset: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells at storage charge need that slow initial cycle to reach rated capacity — skipping it cuts your usable charge short from the start.

Talk time shorter than the original battery after replacement

NiMH cells ship at partial charge and need three to five full charge-discharge cycles before they reach rated capacity. On cycle one, you may get noticeably less talk time than the original pack delivered at its peak. Each full cycle conditions the cells and pushes capacity closer to the rated 170mAh. Run the handset until the low-battery indicator triggers, then return it to the base for a full charge — repeat this three to five times.

Base station showing no charge or error light after fitting new battery

NiMH batteries drop to a low resting voltage during storage — sometimes below the threshold the base station expects before it starts the charge cycle. The base reads this as a fault rather than a discharged pack. Remove the handset, wait 30 seconds, and re-seat it firmly so the contacts are fully engaged. If the error persists, check the base contacts for oxidation and clean them with a dry cloth, then re-seat again.
