About this replacement
Signologies 1300500 / GN9962053 — 4.8V Ni-MH Replacement Battery (PAG0250)
This is a 4.8V, 300mAh Ni-MH replacement battery for the Signologies 1300500, GN9962053, and Perpect Pager paging devices. It slots into the original battery compartment and restores full pager operation when the factory cell has degraded beyond use. Voltage and physical dimensions match the OEM spec.
- 1300500, GN9962053, and Perpect Pager compatibility: These three models share the same 4.8V cell architecture, battery compartment footprint, and contact orientation — a single replacement cell works across all three without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on pager hardware and confirmed the BMS accepted the new cell voltage without triggering a low-battery flag at rest.
- Post-install power cycle: After fitting this cell, power the pager fully off and back on. Some pagers require a fresh boot to re-register on the paging network and reset the low-battery voltage baseline to the new cell's charge state.
Why the 1300500 stops receiving alerts after a battery swap
Pagers like the 1300500 store network registration data in volatile memory that clears when power is fully interrupted. Swapping the battery cuts that power. Without a reboot sequence, the pager may appear on but won't re-establish its link to the paging transmitter. A full power cycle — off, then on — forces the pager to re-register and resume receiving alerts normally.
Low battery indicator showing immediately after fitting a new cell
Ni-MH cells ship at storage voltage, typically around 1.1–1.2V per cell, which sits below the pager's fully-charged threshold. The low-battery indicator fires because the pager reads that resting voltage as depleted. This isn't a faulty cell — it clears after the first full charge cycle. Place the pager on charge until the indicator extinguishes before drawing any conclusions about cell condition.
