Digi-Phone RCL950 Cordless Phone Replacement Battery 3.6V 300mAh

Digi-Phone RCL950 — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 300mAh Ni-MH battery for the Digi-Phone RCL950 cordless telephone handset. It slots into the handset battery compartment and restores power to the wireless unit. Voltage and cell count match the original pack exactly.

• RCL950 handset compatibility: The RCL950 base station expects a 3.6V three-cell NiMH pack. The charging circuit is calibrated to that voltage window and the physical dimensions — 31.40 x 30.17 x 10.81mm — match the original tray without modification.
• Bench tested on actual hardware: We ran this pack through the RCL950 base charging circuit and confirmed the charge acceptance, termination behaviour, and contact engagement all matched a factory-fresh unit.
• First-charge discipline for NiMH cordless packs: After installing, seat the handset in the base and leave it on charge for a full 16 hours before first use. NiMH cells fresh from storage have suppressed capacity — slow charging on the first cycle lets the chemistry reach its rated 300mAh.

Base station charging error on a new NiMH pack

NiMH cells discharged during storage can drop below 3.0V. Some cordless base stations read this as a fault condition and refuse to begin a normal charge cycle. The fix is a trickle pre-charge — either leave the handset seated for several hours without removing it, or use an external NiMH charger to nudge the pack above 3.3V first. Once the voltage crosses the base station's acceptance threshold, the charging LED will switch to its normal cycle.

Talk time shorter than original battery after replacement

A new NiMH pack rarely delivers full rated capacity on the first or second cycle — this is normal chemistry behaviour, not a defective cell. The capacity builds across three to five full charge-and-use cycles as the crystalline structure in the cells stabilises. Run the handset until the low-battery indicator appears, then return it to the base for a full charge each time. By cycle five, talk time should be at or near the 300mAh rated capacity.
