GP 60AAS3BV1Z Cordless Phone Compatible Battery 3.6V 1500mAh

GP 60AAS3BV1Z / 85AAS3BV1Z / 95AAS3BV1Z — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 1500mAh Ni-MH battery pack for cordless DECT handsets using GP OEM references 60AAS3BV1Z, 85AAS3BV1Z, or 95AAS3BV1Z. It replaces the internal rechargeable cell when the original no longer holds a charge through a full day of standby and calls. Voltage, capacity, and physical dimensions (49.00 × 42.90 × 14.74mm) match the factory specification.

• Three OEM references, one cell format: The 60AAS3BV1Z, 85AAS3BV1Z, and 95AAS3BV1Z variants share the same connector orientation, cell count, and voltage rail. GP revised the part number across production runs without changing the physical pack — all three references accept this replacement.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a DECT handset base station. The BMS accepted charge from the first placement, and cell voltage stabilised at 3.6V nominal after three full cycles with no cutoff errors.
• First-charge protocol for Ni-MH handsets: After installing, seat the handset in the base for a continuous 16-hour charge before first use. Ni-MH cordless phone packs ship partially discharged and need a slow initial charge to reach rated capacity — skipping this shortens usable talk time from the start.

Base station showing charging error on a new Ni-MH pack

DECT base stations detect charge acceptance by measuring cell voltage at the contacts. A new Ni-MH pack stored for several months can drop below the base's minimum acceptance threshold — typically around 3.0V — triggering a charge fault or blinking error light. This is not a fault with the battery or the base. Remove the handset, leave it out for 30 seconds, then reseat it firmly. If the error persists, check that the contacts on both the handset and base are clean and making full contact — oxidation on the gold pads is a common cause on units stored unused.

Range drops noticeably under RF load after battery swap

A cordless handset transmits at a fixed RF power level during a call, which pulls more current than standby. If the Ni-MH pack hasn't completed its conditioning cycles, internal resistance is higher than rated, and cell voltage sags under that transmit load. The radio compensates briefly, then the handset drops signal or cuts out at distances it used to handle. Run three full charge-discharge cycles through normal use — after that, internal resistance drops and voltage sag under RF load returns to spec.
