Haier H15132 Replacement Battery 3.7V 1200mAh Li-ion

Haier H15132 / HE-D330 / HE-M360 Series — 3.7V Li-ion Replacement Battery

This 3.7V, 1200mAh Li-ion cell replaces the original battery in the Haier H15132, HE-D330, HE-M002, and HE-M360 handsets. It fits directly into the battery bay with no modification. Capacity is rated at 4.44Wh, matching the stock specification for these models.

• Shared platform fit — H15132, HE-D330, HE-M002, HE-M360: These Haier handsets share the same 3.7V single-cell architecture, connector pinout, and physical envelope. The BMS communication protocol is consistent across this group, so the same cell works across all listed models without any adapter or modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the H15132 platform. The BMS handshake completed normally on first power-up, charge acceptance was stable, and the protection circuit tripped correctly at the low-voltage cutoff threshold during discharge testing.
• Fuel gauge recalibration on first install: After fitting this cell, run one full discharge down to automatic shutdown, then charge uninterrupted to 100% before use. The H15132 fuel gauge IC reads the old cell's discharge curve until it completes this cycle — skipping it causes the percentage display to jump or report inaccurate levels.

Sudden shutdown at 20–30% on the Haier H15132 after a cell swap

The H15132 uses a coulomb-counting fuel gauge that was calibrated to the original cell's internal resistance profile. A new cell has lower impedance, so the voltage under modem or screen load drops steeply at around 3.5–3.6V — a point the gauge still maps to 20–30% remaining. The phone's protection circuit hits the low-voltage floor and cuts power before the gauge catches up. One full discharge-to-shutdown cycle followed by a complete charge resets the coulomb counter reference and eliminates these early shutdowns.

Li-ion cells that sit discharged for weeks can drop below 2.5V per cell, triggering the BMS deep-discharge lockout. In this state the phone draws no current and shows no charging indicator. Connect to a wall charger — not a PC USB port — and leave it for 20–30 minutes without attempting to power on. The BMS trickle-charges the cell up to the recovery threshold (around 2.9V), at which point normal charging resumes and the phone boots.
