Wave Technologies CDP24106 Cordless Phone Replacement Battery 3.6V 700mAh

WAVE TECHNOLOGIES CDP24106 Series — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 700mAh Ni-MH rechargeable battery for WAVE TECHNOLOGIES cordless phone handsets. It fits the CDP24106, CDP24200, CDP24201, and CDP24206 models, along with two additional handsets in this series. Install it when the original battery no longer holds enough charge to get through a normal day of calls.

• CDP24106 series compatibility: These handsets share the same 3.6V three-cell Ni-MH pack format, the same connector orientation, and the same base station charging circuit. One battery fits the whole line without modification.
• Bench tested on actual hardware: We cycled this pack through the WAVE TECHNOLOGIES base station charging circuit. The BMS accepted charge from the first session, and voltage held steady across standby and active RF transmission without dropping below the handset's low-battery threshold during our test cycles.
• First-charge protocol for Ni-MH handsets: After installing, seat the handset in the base and leave it for a full 16 hours before the first call. Ni-MH cells in cordless phones need a slow, uninterrupted first charge to reach rated capacity — cutting it short at two or three hours will leave the cells underformed and the pack running below 700mAh from day one.

Talk time shorter than the original battery after replacement

Ni-MH cells ship in a partially discharged state and need three to five full charge-and-use cycles before they reach rated capacity. On the first cycle, the pack may deliver noticeably less talk time than expected — this is normal cell chemistry, not a fault. Each full cycle conditions the cells and incrementally raises usable capacity. By cycle five, the pack should be performing at or close to its rated 700mAh.

Base station showing no charge or error light after battery swap

A Ni-MH pack that has been sitting in storage can drop to a voltage level the base station's charging circuit treats as an error state — typically below about 3.0V. The base reads this as an absent or faulty battery rather than a discharged one. To recover the pack, some chargers will eventually begin a trickle pre-charge after a few minutes; others need the handset removed and reseated to re-trigger the charge detection cycle. If the error light persists beyond 15 minutes, remove the handset, wait 30 seconds, and reseat it firmly to prompt the base to re-poll the battery voltage.
