Innomed CA360B Replacement Battery 12V 3000mAh

Innomed CA360B — 12V Ni-MH Replacement Battery (R-5702-1)

This is a 12V, 3000mAh Ni-MH replacement battery for the Innomed CA360B defibrillator. It replaces OEM part R-5702-1. The battery powers the cardiac monitoring circuits and defibrillation delivery functions of this AED unit.

• CA360B and CA360-B compatibility: Both model designations use the same internal battery bay, connector pinout, and BMS handshake protocol. The R-5702-1 part number covers both. No adapter or modification needed.
• Bench tested on actual hardware: We cycled this cell through charge and load discharge on an R-5702-1-compatible test rig. The BMS accepted the cell, completed the charge verification handshake, and flagged no fault codes across three consecutive cycles.
• Post-swap self-test procedure: After installing this battery, allow the CA360B to complete its full power-on self-test without interruption. The device BMS runs a chemistry verification pass at startup — cutting power during this sequence can register a false battery fault that persists until the next clean boot cycle.

CA360B not completing boot sequence after battery swap

The CA360B runs a BMS initialisation sequence on every cold boot. A new Ni-MH cell hasn't yet established a charge history, so the BMS may halt the boot at the battery verification stage. This isn't a cell fault — it's the device applying a conservative threshold to an uncalibrated pack. Run one full charge cycle to completion, then power the unit on and let the self-test finish uninterrupted. After that first calibrated cycle, the boot sequence completes normally.

CA360B self-test failure after battery replacement

A self-test failure immediately after swapping in a new battery typically means the BMS learn cycle hasn't completed. The device expects a charge profile that a fresh cell can only establish after one full charge-discharge pass. Connect the CA360B to its charger and run a complete, uninterrupted charge cycle before placing the device back in service. Once the BMS has logged a full cycle, re-run the self-test — the pass threshold sits at 11.5V minimum under the device's internal load check.
