Nomad 22250X Cordless Phone Replacement Battery 3.6V 2000mAh

Nomad 22250X / 3095 / 3470 Series — 3.6V Ni-MH 2000mAh Replacement Battery

This is a 3.6V Ni-MH replacement battery rated at 2000mAh (7.2Wh) for Nomad cordless handsets. It fits the 22250X, 22251X, 3095, and 3470 models. The cell format matches the original pack, so it drops into the battery compartment without modification.

• 22250X, 22251X, 3095, and 3470 compatibility: These four handset models share the same 3.6V three-cell Ni-MH pack format and use the same connector orientation. One battery SKU covers all four because the voltage rail, physical footprint, and BMS charge acceptance are identical across the range.
• Bench tested on actual hardware: We ran this pack through charge and talk cycles on a 3470 handset. The base station accepted the charge signal without flagging an error, and the BMS held a stable voltage curve through draw cycles typical of DECT transmission bursts.
• First-charge protocol for Ni-MH handsets: After installing the battery, seat the handset in the base for a full 16-hour charge before first use. Ni-MH cells shipped in a partial state of charge will not reach rated capacity on a standard top-up cycle — the slow first charge is what conditions the cells to their full 2000mAh rating.

Nomad base stations detect a new battery by reading an initial voltage handshake. A Ni-MH pack stored for several months can drop below 3.0V, which sits outside the base's acceptance window. When that happens, the charge indicator stays off or shows an error even though the contacts are clean and correctly seated. The fix is to seat the handset firmly, leave it for 30 minutes, then remove and reseat it — most Nomad bases will retry the detection cycle and begin trickle charging once the cell voltage recovers slightly from contact warmth and passive recovery.

Handset loses pairing with the base after the battery is removed

DECT handsets store pairing data in volatile memory backed by the battery. Removing the battery fully — even briefly — clears that stored pairing on some Nomad models. The handset will power on but show no base connection and fail to place calls. To fix this, put the handset in registration mode from the base station menu and re-pair it as if adding a new handset. Most Nomad models do this by holding the registration button on the base for three seconds while the handset is powered on.
