Code A Phone 3150 Cordless Phone Replacement Battery 3.6V 600mAh

Code A Phone 3150 / 7010 Series — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 600mAh Ni-MH replacement battery for Code A Phone cordless handsets. It fits the 3150, 3260, 7010, and 7015 series, along with three additional compatible models. Same voltage, same chemistry, same connector footprint as the original pack.

• 3150 / 3260 / 7010 / 7015 platform fit: These models share the same 3.6V NiMH cell format and base-station charging circuit. The BMS handshake is passive on this chemistry — no digital authentication to worry about. Voltage and connector geometry are what matter here, and both match.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a DECT handset platform. The NiMH cells accepted full charge current from the base cradle without triggering a charge-fault light. Capacity came up to spec by the third cycle, which is normal for NiMH chemistry.
• First-charge protocol for NiMH cordless handsets: After installing, seat the handset in the base and leave it for a full 16 hours before the first use. NiMH cells ship partially discharged from storage. A slow first charge lets all three cells in the pack balance properly and reach rated capacity from the start.

Talk time shorter than original battery after replacement

NiMH cells need three to five full charge-discharge cycles before they hit rated capacity. A new pack straight from storage will underperform the original for the first few uses — that is not a fault. Run the handset until the low-battery beep triggers, return it to the base for a full 16-hour charge, and repeat. By cycle four, capacity stabilises at the 600mAh rating.

Base station showing no-charge or error light after installing new pack

NiMH batteries that have been in storage can drop below 3.0V across the pack. Some Code A Phone bases read that as an error condition and refuse to initiate a charge cycle. Remove the handset, wait 10 seconds, then reseat it firmly — the base re-polls the pack voltage on contact. If the error light persists, the pack voltage may need a brief boost: place the handset in the base, press and hold the talk key for five seconds, then release. This nudges the base into a recovery charge at reduced current.
