6V Visonic Next CAM Compatible Battery 1350mAh Li-MnO2

Visonic Next CAM Series — 6V Li-MnO2 Replacement Battery (103-302891)

This is a 6V, 1350mAh lithium manganese dioxide cell for the Visonic Next CAM, Next CAM PGS, Next CAM K9 PG2 wide angle, and Next CAM PG2 wireless security cameras. It replaces OEM part 103-302891 and cross-references GP2CR123A, EVE2CR17450-C, and OSA363. Voltage and capacity match the original spec exactly.

• Next CAM platform fit: The Next CAM range shares a common 6V battery bay and BMS handshake across PGS, K9 PG2, and PG2 variants. All models draw from the same voltage rail, so one cell covers the full lineup without adapter or modification.
• Bench tested on actual hardware: We ran this cell through motion-trigger cycles on the Next CAM platform. The BMS handled the combined IR LED and processor current spike on trigger events without dropping out, and voltage held steady across repeated activations.
• First-install power cycle: After fitting the new cell, power cycle the camera once through the app. The Next CAM firmware must register the fresh cell before motion events log correctly to cloud storage — skipping this step can cause missed recordings on the first trigger cycle.

App showing 0% or incorrect percentage after fitting this cell

The Next CAM does not use a fuel gauge IC. It reads capacity by sampling cell voltage against a fixed threshold table. A fresh Li-MnO2 cell sits at a slightly different resting voltage than a partially discharged original, which can confuse the indicator immediately after swap. Run one full motion-trigger session to let the camera sample voltage under real load. The percentage display corrects itself once the firmware maps the new cell's discharge curve — no reset required beyond that.

Camera goes offline in app after battery replacement

Removing the battery clears the active firmware session token on the Next CAM. When power returns, the camera re-initialises its radio stack but does not always re-register automatically with the panel. Open the PowerMaster or Visonic Go app, navigate to device settings, and re-enrol the camera. If the status stays offline after re-enrolment, check that cell voltage reads at least 5.8V under the camera's standby draw before assuming a connection fault.
