About this replacement
Videofied W Panel Wireless Alarm System — 3.7V Li-ion Replacement Battery (WBAT100)
This is the WBAT100 3.7V Li-ion cell for Videofied W panel wireless alarm systems. It fits the W panel range used in perimeter protection and intrusion detection setups. Capacity is 2600mAh (9.62Wh) — matching the original specification.
- W panel platform fit: Videofied W panels share a common 3.7V single-cell architecture with the WBAT100 connector and BMS handshake. Swapping this cell keeps the panel in communication with the control system without triggering a fault on the bus.
- Bench tested on actual hardware: We cycled this cell through a full charge and discharge sequence on the W panel platform. The BMS accepted the cell cleanly, reported charge status correctly, and held voltage within spec across the full test window.
- Post-installation float charge window: Do not run a zone test immediately after fitting this cell. Allow 24–48 hours on float charge first. The panel samples battery voltage during diagnostics — a partially charged new cell will trigger a false low-battery report on the panel display.
Alarm panel losing saved programming during a power outage after battery swap
A new Li-ion cell needs time on the charger before the panel treats it as a conditioned backup source. If mains power drops within the first 48 hours after fitting, the panel may draw more current than the unconditioned cell can sustain at voltage. When cell voltage sags below the panel's hold threshold, the MCU loses its RAM-backed configuration. Install the new cell, restore mains power, and leave the panel undisturbed for 48 hours before testing backup operation. After that window, the cell should hold the panel above 3.0V through a typical outage cycle.
Panel shows tamper fault immediately after battery access
Videofied W panels use a lid or cover tamper switch that the panel polls on startup and after any wake event. If the enclosure cover is not fully seated after a cell swap, the tamper circuit stays open and the panel logs a tamper fault to the control system. Check that all enclosure clips or screws are fully engaged — a partially closed lid is the most common cause. Once the cover is properly closed, the tamper fault should clear on the next panel check-in without a full system reset.
