Audioline CDL960G Replacement Battery 3.6V 600mAh

Audioline CDL960G / CDL970G Series — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 600mAh Ni-MH rechargeable battery for Audioline cordless DECT handsets. It fits the CDL960G, CDL970G, BT-C150, CDL100, and fourteen additional models that share the same cell format and connector. Swap it when the original no longer holds charge through a full conversation.

• CDL960G / CDL970G platform fit: These models share a 3.6V single-cell NiMH architecture with matching connector pinout and physical dimensions (40 × 42 × 13.5mm). The base station charges at a low trickle rate calibrated to this cell voltage — swapping in a different voltage pack triggers charge errors.
• Bench tested on actual hardware: We cycled this pack through the CDL960G base station, confirming the charge acceptance handshake, full trickle-to-ready transition, and BMS cutoff at low-voltage threshold — no false charge errors observed across five consecutive cycles.
• First charge on NiMH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells shipped in storage state need a slow initial charge to reach rated 600mAh capacity — cutting this short leaves the pack operating below spec for the first several cycles.

Talk time shorter than rated after replacing the CDL960G battery

NiMH cells arrive partially discharged from storage and won't deliver rated capacity on the first charge cycle. The CDL960G base charges at a low trickle current — this is correct but means the first few cycles may feel short. Capacity builds over three to five full charge-and-use cycles as the cells condition. By cycle five, the pack should be consistently reaching close to its 600mAh rating.

CDL960G handset not pairing with base after battery swap

Removing the battery from a DECT handset cuts all power, which can erase the pairing memory on some Audioline models. The handset and base lose their registered link when voltage drops to zero during the swap. To fix this, re-register the handset through the base station menu — typically accessed by holding the page/find button on the base for five seconds. Once registered, the handset will reconnect and charge normally.
