BAT-F10 Acer Liquid E600 Compatible Battery 3.8V 2500mAh

Acer Liquid E600 — 3.8V Li-Polymer Replacement Battery (BAT-F10)

This is a 3.8V, 2500mAh lithium-polymer battery for the Acer Liquid E600 smartphone. It replaces OEM part BAT-F10 (also referenced as KT.0010S.012). Install it when the original cell no longer holds charge across a full day of calls, messaging, and app use.

• Liquid E600 fitment: The E600 uses a slim Li-Polymer cell with a specific connector orientation and BMS handshake tied to the phone's charge IC. This cell matches the 67.46 × 55.40 × 4.47mm envelope and the BAT-F10 connector — the BMS communicates correctly with the E600's fuel gauge IC without triggering a rejection flag.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the E600 platform. The BMS accepted the charge protocol, voltage held steady under combined modem and display load, and the cell did not trigger thermal cutoff during sustained use.
• Fuel gauge recalibration on first use: Disable fast charging for the first complete discharge-charge cycle after fitting this cell. The E600's fuel gauge IC is calibrated to the old cell's discharge curve — one slow cycle lets it remap against the new cell before fast charge pushes higher current into an uncalibrated state.

Sudden shutdown at 20–30% on the Liquid E600

This happens when the cell cannot sustain voltage under peak load from the modem radio or display backlight. The fuel gauge IC reads state-of-charge from a stored discharge curve — if that curve doesn't match the new cell, it misreads remaining capacity. The phone shuts down not because the cell is empty, but because voltage drops below the safe threshold under load before the gauge catches up. One full slow discharge-charge cycle forces the coulomb counter to resync against the actual cell behaviour, which typically resolves the early cutoff.

Phone feels warm near the battery during the first few charges

A new Li-Polymer cell has higher internal impedance than a broken-in cell. The E600's charge IC pushes current into that higher impedance, which generates more heat than you'd see with a well-cycled cell. This is normal for the first two or three cycles and reduces as internal impedance drops. If warmth persists beyond the third charge cycle, check that the replacement cell is seated flat with no pressure on the pack — any flex in the pouch increases impedance and heat.
