Master Veraphone Micro Cordless Phone Replacement Battery 3.6V

Master Veraphone Micro — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 300mAh Ni-MH replacement battery for the Master Veraphone Micro cordless handset. It slots into the handset battery compartment and restores full wireless operation when the original cell no longer holds charge. Voltage and physical dimensions match the original pack: 31.40 × 30.17 × 10.81mm.

• Veraphone Micro handset fit: The Veraphone Micro uses a compact 3.6V single-cell Ni-MH pack at this exact footprint. Swapping to a different voltage or a larger cell risks a poor fit and incorrect charging from the base station's trickle circuit.
• Bench tested on actual hardware: We cycled this pack through the base station charge circuit and confirmed the BMS accepted the NiMH voltage profile without triggering a charge fault. Capacity output stabilised after three full charge-discharge cycles, which is normal for Ni-MH chemistry.
• First-charge protocol for NiMH cordless handsets: After installing, seat the handset in the base for a full 16-hour charge before first use. NiMH cells arriving from storage are partially depleted — a slow first charge lets the chemistry reach rated capacity across all cells in the pack.

Base station showing no charge light after fitting the new pack

The Veraphone Micro base uses a trickle charge circuit that checks for a minimum voltage before switching on the charge indicator. A new NiMH pack straight from storage can sit at or below that threshold — around 3.2V — which causes the base to see no valid battery and withhold charge current. The fix is to leave the handset seated in the base undisturbed for up to 30 minutes; the trickle circuit will slowly bring the pack above the acceptance threshold and the charge light will come on. If the indicator still does not appear after 30 minutes, remove and reseat the handset to re-trigger the detection cycle.

Range drops noticeably mid-call after battery swap

NiMH cells sag under the RF transmit load of a DECT handset — voltage dips during transmission bursts, and if the pack is not yet fully conditioned, that sag is worse. The handset's transmit power drops when supply voltage falls, and range shrinks as a result. This typically self-corrects after three to five full charge-discharge cycles, which bring the pack to its rated 300mAh capacity. Run the handset until it signals low battery, then return it to the base for a full charge — repeat this three times and range will stabilise.
