Cheetah Range 2.4V Ni-MH Cordless Phone Replacement Battery 750mAh

Cheetah Range E3250 / Easy Touch Series — 2.4V Ni-MH Replacement Battery

This 2.4V 750mAh Ni-MH battery replaces the original rechargeable pack in Cheetah Range cordless handsets including the E3250, Easy Touch 100, Easy Touch 200, and related models. It matches the original voltage and connector footprint so the handset seats and charges in the base as normal. Capacity is 750mAh (1.8Wh) — identical to the factory specification.

• E3250 and Easy Touch compatibility: These handsets share the same 2.4V two-cell NiMH pack format and base-charging circuit. The replacement matches that voltage rail and physical dimensions (44.07 × 20.35 × 10.58mm), so the base station sees a normal charge profile without triggering fault indicators.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the bench. The NiMH cells reached rated capacity between cycles three and five — consistent with normal NiMH conditioning behaviour on cordless phone handsets.
• First-charge protocol for NiMH handsets: After installing, seat the handset in the base for a full 16-hour charge before first use. NiMH cordless batteries arrive partially discharged from storage and require a slow first charge to reach rated capacity — skipping this step leaves the cells under-conditioned from the start.

Base station charge light not activating on a new NiMH pack

Cheetah Range base stations use a threshold voltage check before enabling the charge circuit. A NiMH pack that has sat in storage can drop low enough that the base rejects it as a fault rather than charging it. Place the handset in the base anyway and leave it for 30 to 60 minutes — most base units will detect a slow voltage rise and begin a normal charge cycle. If the charge light still does not activate after that window, check the handset contacts against the base pins for oxidation and clean with a dry cloth.

Range drops noticeably during calls after replacing the battery

DECT transmit power depends on the handset maintaining stable voltage during RF bursts. When a NiMH pack is under-conditioned or partially discharged, voltage sags under the RF load and the handset pulls back transmit power to protect the circuit. The result is shorter effective range even though the handset appears to be on and functional. Run three to five full charge-and-use cycles to condition the cells — voltage under RF load stabilises once the cells reach rated capacity.
