T-Plus Europa 40i Replacement Battery 3.6V 1200mAh Ni-MH

T-Plus Europa 40i — 3.6V Ni-MH Replacement Battery

This is a 3.6V Ni-MH battery rated at 1200mAh (4.32Wh), built to fit the T-Plus Europa 40i cordless handset. It replaces the original cell pack when the handset stops holding a charge or stops powering on altogether. Dimensions are 56.32 x 42.96 x 20.38mm — confirm against your existing pack before installing.

• Europa 40i handset fit: The Europa 40i uses a 3.6V three-cell Ni-MH configuration to meet the handset's DECT transmit power and standby draw requirements. Swapping to a different voltage or chemistry trips the charging circuit and causes error indicators at the base.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a cordless phone test rig. The BMS accepted charge current from a standard DECT base station without cutoff events, and cell voltage held stable across the discharge curve.
• First-charge conditioning for Ni-MH: After fitting the battery, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells shipped from storage sit below rated capacity — a slow, uninterrupted first charge lets all three cells balance and reach full capacity together.

Talk time shorter than the original battery after replacement

New Ni-MH cells typically deliver 60–70% of rated capacity on the first few cycles. This is normal — it is not a fault with the pack. The cells need three to five full charge and discharge cycles before the internal chemistry stabilises and capacity reaches the rated 1200mAh. Run the handset down to low-battery indicator, then return it to the base for a full charge each time. Talk time improves noticeably by cycle three.

Ni-MH packs lose voltage during storage and shipping. If the cell voltage drops too low, some DECT base stations reject the charge cycle and flag an error instead of charging. Remove the handset, hold the power button for five seconds to drain residual circuit charge, then reseat firmly in the base. If the base still shows an error after 30 minutes, the pack voltage may need a short external boost charge to 3.2V before the base station's charge controller will accept it.
