Build integration

The pack measures 47.52 x 34.18 x 6.58 mm and slides into the handset battery compartment without modification. No soldering or additional wiring is required; the existing connector aligns with the original layout. It frees the handset from a tethered power supply, restoring cordless operation around the desk. The single-cell design keeps the installation straightforward for office staff.

Thermals and power

Ni-MH chemistry delivers a nominal 3.6 V and 550 mAh capacity, yielding 1.98 Wh of energy for typical talk and standby cycles. The cell runs at room temperature during normal use and produces no audible noise. Self-discharge is low enough to hold charge over weekends without a dock. The pack contains no liquid electrolyte, so there is no leak risk under standard office conditions.
