GE 49001 Cordless Phone Replacement Battery 6V 1500mAh Ni-MH

GE 49001 / GES-PCM02 — 6V Ni-MH Replacement Battery

This is a 6V 1500mAh Ni-MH replacement battery for the GE 49001 and GES-PCM02 cordless phone handsets. It slots into the handset battery compartment and restores wireless operation from the base station. Voltage and cell count match the original pack exactly.

• 49001 and GES-PCM02 compatibility: Both models run the same 6V battery rail with identical connector pinout and physical footprint. The base station charger circuit targets this voltage range, so swapping packs between these two handsets works without modification.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a GE 49001 handset. The BMS accepted charge immediately from the base cradle, and voltage held steady across the RF transmit bursts without dropping below the handset's low-battery threshold.
• First charge on NiMH cordless packs: After installing, seat the handset in the base for a full 16-hour charge before first use. NiMH cells ship partially discharged. A slow, full first charge lets each cell reach rated capacity — skipping this step can leave 20–30% of capacity permanently inaccessible.

Why talk time stays short for the first few uses after a new NiMH swap

NiMH cells don't hit rated capacity on the first cycle. The 1500mAh figure requires 3–5 full charge and discharge cycles to develop fully. On cycle one, effective capacity can sit at 60–70% of rated. Each subsequent full cycle builds the capacity up further. Run the handset until the low-battery alert triggers, return it to the base for a full charge, and repeat — talk time will increase noticeably by cycle three.

Base station charge light not activating after fitting the new pack

NiMH batteries stored for several months can drop below 4.5V, which sits outside the acceptance window for some GE base charger circuits. The charger reads the pack as faulty rather than deeply discharged and refuses to initiate the charge cycle. To recover, briefly connect the battery to a standalone NiMH charger set to 6V until voltage climbs above 5.0V, then return the handset to the base. Once the base sees a voltage in its acceptance range, the charge light activates and normal charging resumes.
