Alcatel Altiset Easy L Cordless Phone Replacement Battery 3.6V 600mAh

Alcatel Altiset Easy L / Altiset Pro I / OneTouch Plus — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 600mAh Ni-MH replacement battery for the Alcatel Altiset Easy L, Altiset Pro I, and OneTouch Plus cordless phone handsets. It slots into the handset battery compartment and restores charge capacity lost when the original cell degrades. Voltage and physical dimensions match the factory specification exactly.

• Altiset Easy L, Altiset Pro I, OneTouch Plus compatibility: All three handsets run the same 3.6V single-cell Ni-MH rail, share the same connector pinout, and use the same physical bay dimensions — 42.64 x 30.00 x 14.45mm. No modification required to fit any of these models.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on DECT handset hardware. The BMS accepted charge from the base station without error, and cell voltage held stable across the discharge curve with no mid-cycle drop-out detected.
• First charge on a new Ni-MH pack: After fitting, place the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells arrive partially discharged from storage and require a slow initial charge cycle to reach their rated 600mAh capacity. Pulling the handset early will reduce your usable capacity on the first several cycles.

Talk time shorter than the original battery after replacement

Ni-MH cells do not deliver full rated capacity straight out of the box. The electrochemical structure needs three to five full charge-discharge cycles before the cells reach their stated 600mAh. During those early cycles, talk time will be noticeably lower than the original battery at its prime. Run full cycles — charge completely in the base, then use the handset until it prompts you to charge again — and capacity will rise each time.

Base station charge light not activating after fitting a new battery

A Ni-MH pack sitting in warehouse storage can drop to a voltage level the base station's charging circuit reads as a fault rather than a depleted battery. The base applies a brief voltage check before committing to a charge current, and a deeply discharged cell can fall below that threshold. Remove the handset, wait 10 seconds, and reseat it firmly in the base to trigger a fresh detection cycle. If the charge light still does not activate, confirm the handset contacts and base cradle contacts are clean — oxidation on either surface interrupts the circuit. A resting pack voltage above 3.0V will typically clear the error on the next seating.
