Philips PMC7230 Replacement Battery ABC6A 3.7V 2200mAh

Philips PMC7230 — 3.7V Li-ion Replacement Battery (ABC6A)

This is a 3.7V, 2200mAh Li-ion replacement battery for the Philips PMC7230 and PMC7230/17 portable media players. It matches the OEM part number ABC6A and slots into the same battery bay as the factory cell. Capacity figures come from the product data — 8.14Wh total energy.

• PMC7230 and PMC7230/17 compatibility: Both variants share the same 3.7V single-cell architecture and the same ABC6A connector and BMS handshake, so one cell covers both model suffixes without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the PMC7230 platform and confirmed the BMS accepted full charge termination without triggering overcurrent or overvoltage faults.
• First-charge protocol on the PMC7230: After installing a new cell, connect the charger before attempting to power on. Media players stored or shipped with a deeply discharged cell often enter a protection state that blocks normal boot — a slow trickle charge for 20–30 minutes clears the protection latch and lets the BMS accept a full charge cycle.

Battery percentage jumping after a cell swap on the PMC7230

After fitting a new cell, the PMC7230's fuel gauge reads from voltage thresholds it calibrated against the old, degraded cell. The new cell has a flatter discharge curve at higher capacity, so the reported percentage jumps or drops unexpectedly during the first few sessions. Run two to three full charge-to-discharge cycles and the gauge recalibrates its internal voltage-to-percentage mapping. After that, readings stabilise and track accurately down to the low-voltage cutoff near 3.0V.

Playback cutting out before the battery indicator shows empty

At the tail end of a discharge cycle, cell voltage drops faster than the fuel gauge updates. The audio amplifier inside the PMC7230 draws a short current spike on each track start, and if the cell is already below roughly 3.2V, that spike pulls voltage under the BMS cutoff threshold and the player shuts down mid-track. The gauge may still show one or two bars at the point of cutoff. Plug in the charger immediately — do not leave the cell sitting discharged, as extended time below 3.0V accelerates capacity loss in Li-ion cells.
