Verge V58CID Replacement Battery 3.6V 700mAh Ni-MH

Verge V58CID / V58HS / V58ITA — 3.6V Ni-MH Replacement Battery

This is a 3.6V 700mAh Ni-MH replacement battery for the Verge V58CID, V58HS, and V58ITA cordless handsets. It restores talk time and standby capacity when the original cell no longer holds a useful charge. Dimensions are 45.60 × 31.30 × 10.60mm — confirm these match your existing pack before ordering.

• V58 series handset fit: The V58CID, V58HS, and V58ITA all run the same 3.6V single-cell NiMH pack on a shared voltage rail with identical connector geometry. One battery covers all three models.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the V58CID platform. The cell accepted a full charge from the base station without triggering a charging fault, and voltage held stable under RF transmit load.
• First charge on NiMH cordless packs: After installing, seat the handset in the base for a full 16-hour uninterrupted charge before first use. NiMH cells shipped in storage discharge need a slow initial charge to reach rated capacity — skipping this step leaves you with noticeably shorter talk time from day one.

Talk time shorter than the original battery after replacement

NiMH cells do not deliver rated capacity on the first cycle out of the box. Storage discharge leaves the cell partially passivated, and it takes three to five full charge-and-use cycles before the chemistry reaches full capacity. Do not judge the battery on the first day. Run the handset down to low battery, return it to the base for a full charge, and repeat — by cycle four or five, talk time should be at or near rated output.

Base station shows no charge or error light after swapping the battery

A NiMH pack that has sat in storage can drop below the voltage threshold the base station expects before it initiates a charge cycle. Some Verge base stations will show a fault light or simply not register the handset as charging. Remove the handset, wait 10 seconds, and reseat it firmly — the base needs a clean contact to sense the pack. If the fault persists, check that the contacts on both the handset and cradle are clean and making full metal-to-metal contact; oxidised contacts block the low-current trickle needed to bring a depleted NiMH cell back up to the charge acceptance threshold of around 1.0V per cell.
