AB1400CWMT Philips E160 Replacement Battery 3.7V 1300mAh

Philips Xenium E160 — 3.7V Li-ion Replacement Battery (AB1400CWMT)

This is a 3.7V, 1300mAh Li-ion replacement battery for the Philips E160 and Xenium E160 mobile phone. It matches the OEM part number AB1400CWMT and fits the original battery slot without modification. Voltage and capacity are sourced directly from product specifications — not estimated.

• E160 and Xenium E160 compatibility: Both the E160 and Xenium E160 share the same battery bay geometry, connector pinout, and 3.7V nominal voltage rail. One cell fits both variants — no adapter or wiring change needed.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the E160 platform. The BMS handshake completed correctly, charge acceptance was normal, and the protection circuit tripped as expected at low-voltage cutoff.
• Fuel gauge recalibration on first use: On first installation, disable fast charging if your charger supports it, then run one complete discharge-charge cycle at standard current. This lets the fuel gauge IC map its reference points against the new cell's actual discharge curve before higher charge rates are applied.

Sudden shutdown at 20–30% on the Philips E160

The E160's fuel gauge IC was calibrated to the original cell's discharge curve. When a new cell is installed, that curve no longer matches — so the reported percentage drifts from actual cell voltage. Under load from a call or screen-on event, the cell voltage drops below the BMS cutoff threshold while the OS still shows 20–30% remaining. The fix is one full discharge-to-shutdown cycle followed by an uninterrupted charge to 100%. After that single cycle, the coulomb counter re-anchors to the new cell's actual capacity.

Phone warm near the battery during the first charge after replacement

A new Li-ion cell typically has higher internal impedance than a broken-in cell. During the first charge cycle, the charge IC works against this higher impedance, which generates more heat than normal at the battery contact area. This is not a fault — it resolves after one or two full cycles as the cell's impedance settles. If the case becomes hot to the touch rather than warm, stop charging and check that the battery is seated flat with no contact between the cell and any metal edges inside the bay.
