Swissvoice Aeris 196T Replacement Battery 2.4V 600mAh

Swissvoice Aeris 196T / 196PT — 2.4V Ni-MH Replacement Battery

This is a 2.4V, 600mAh Ni-MH battery pack for the Swissvoice Aeris 196T and Aeris 196PT cordless phone handsets. It replaces the original cell when the handset no longer holds a useful charge. Dimensions are 35.40 × 32.50 × 6.70mm — confirm these match your existing pack before ordering.

• Aeris 196T and 196PT compatibility: Both models share the same handset housing, battery bay dimensions, and 2.4V supply rail. The connector orientation and cell footprint are identical across this pair, so one pack covers both.
• Bench tested on actual hardware: We ran charge and discharge cycles on this pack using a NiMH-compatible charger at the correct termination voltage. The BMS accepted charge without delta-V cutoff errors across repeated cycles.
• First-charge protocol for NiMH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells arrive partially discharged from storage. Skipping the slow initial charge leaves the pack well below rated capacity from the start.

Range drops on the Aeris 196T after fitting a new NiMH pack

The Aeris 196T's RF transmitter draws a short current spike each time the handset communicates with the base station. A NiMH pack that hasn't completed its first few conditioning cycles has higher internal resistance than a fully conditioned cell. That resistance causes the voltage to sag under the RF load, reducing transmit power and cutting effective range. After three to five full charge-discharge cycles, internal resistance drops and the voltage holds steady — range returns to normal.

Base station shows no charge or error light after installing the replacement pack

NiMH packs can drop to 1.8V or lower during extended storage. Some cordless base stations won't initiate a charge cycle if the incoming cell voltage is too low — the charger circuit reads the pack as faulty. Remove the handset, wait 30 seconds, then reseat it firmly in the base. If the error persists, use a standalone NiMH charger to bring the pack above 2.0V before returning it to the base cradle.
