Doro 950 Cordless Phone Replacement Battery 3.6V 600mAh

Doro 950 / 955 — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 600mAh Ni-MH battery for the Doro 950 and 955 cordless handsets. It replaces the original cell pack that powers the handset between charges. When the original battery no longer holds a charge, this is a direct swap that restores normal handset operation.

• 950 and 955 compatibility: Both models use the same battery compartment, connector orientation, and charge circuit. The 3.6V NiMH cell pack fits either handset without modification.
• Bench tested on actual hardware: We ran this pack through the Doro charge circuit and confirmed the BMS accepted charge current correctly. Voltage at full charge stabilised at the expected NiMH peak without triggering a fault on the base station.
• First charge on NiMH cordless packs: After installing, seat the handset in the base for a full 16-hour charge before first use. NiMH cells in cordless phones need a slow initial charge to reach rated capacity — skipping this leaves the pack under-conditioned for the first several cycles.

Talk time shorter than expected after the first few charges

NiMH cells need three to five full charge-discharge cycles before they reach rated capacity. A new pack pulled from storage has partially discharged cells that haven't yet been conditioned. Each full cycle pushes the chemistry closer to its 600mAh rating. If talk time is still short after five complete cycles, check that the handset is fully seated in the base — a poor contact means the pack is only getting a surface charge.

Base station shows no charge light or error after battery swap

NiMH packs lose voltage during storage, and some base stations won't initiate a charge cycle if the incoming battery voltage reads too low. The Doro base checks for a minimum voltage before it starts the charge current. If the charge light doesn't come on, remove the handset, wait 10 seconds, and reseat it firmly — this resets the base station's detection cycle. If the error persists, the pack may need a brief charge from an external NiMH charger at 3.6V to bring it above the acceptance threshold.
