Cidco 102794-01 Cordless Phone Compatible Battery 3.6V 1500mAh

Cidco 102794-01 / 104212-01 Series — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 1500mAh Ni-MH battery for Cidco cordless handsets, including models 102794-01, 104212-01, 60AAS3B1Z, 60AAS3B2, and over 25 compatible variants. It replaces the original pack when the handset can no longer hold a charge long enough for a full call. Physical dimensions are 49.00 x 42.90 x 14.74mm — confirm these match your handset bay before ordering.

• Cidco handset compatibility: These Cidco models share the same 3.6V single-cell Ni-MH voltage rail and battery bay geometry. The connector orientation and tab spacing are consistent across the listed variants, so one pack covers the full range without modification.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a Cidco handset base. The BMS accepted charge without error at cycle one, and capacity tracked upward across the first three cycles — typical Ni-MH behaviour before the cells reach rated output.
• First-charge protocol for Ni-MH handsets: Place the handset in the base for a full 16-hour charge before first use. Ni-MH cordless phone cells require a slow initial charge to reach rated capacity — skipping this step is the most common reason a new battery underperforms out of the box.

Talk time shorter than the original battery after replacement

Ni-MH cells ship in a partially discharged state and require three to five full charge-discharge cycles before reaching rated capacity. On the first cycle, you may get noticeably less talk time than expected — this is not a fault. Each subsequent full cycle conditions the cells further. By cycle five, output should be at or near the rated 1500mAh.

Base station charge light not activating on a new pack

Ni-MH batteries that have been in storage can drop below the voltage threshold the base uses to detect a valid battery. If the charge indicator stays off or shows an error, the base may not recognise the pack as chargeable. Remove the handset, wait 10 seconds, and reseat it firmly — contact between the charge pins needs to be clean and flush. If the light still does not activate, check that the resting voltage of the new pack is above 3.0V using a multimeter before assuming a base fault.
