Dopod Touch ELF0160 Replacement Battery 3.7V 2000mAh

Dopod Touch / S1 / S500 — 3.7V Li-ion Replacement Battery (ELF0160)

This is a 3.7V Li-ion battery rated at 2000mAh (7.4Wh), replacing OEM part ELF0160 in the Dopod Touch, S1, and S500 smartphones. It fits the same bay as the original cell and connects to the same three-pin fuel gauge circuit. Dimensions are 50.84 × 36.65 × 10.78mm — measure your bay before ordering if your unit has been serviced before.

• Touch, S1, and S500 compatibility: All three models share the same battery bay geometry, connector pinout, and BMS handshake protocol. The fuel gauge IC on each device reads the same cell identification data, so this replacement integrates without triggering a fault state on any of the three platforms.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the Touch platform. The BMS accepted charge current without interruption, and protection circuits tripped correctly at the low-voltage cutoff threshold — no runaway, no false full-charge flag.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins against an uncalibrated coulomb counter.

Sudden shutdown at 20–30% on the Dopod Touch after a cell swap

This happens because the fuel gauge IC is still running the discharge curve from the old, degraded cell. When the new cell hits a voltage region the IC doesn't expect, it reports remaining charge incorrectly and the device shuts off to protect the SoC. The fix is one full uninterrupted discharge-to-cutoff followed by a full charge — this forces the coulomb counter to relearn the actual capacity. After that cycle, shutdowns at 20–30% should stop. If they continue, confirm the cell voltage at shutdown with a multimeter; it should read above 3.4V.

Device won't power on after sitting in storage with the replacement cell installed

If the phone was stored discharged for an extended period, the cell may have self-discharged below the BMS lockout threshold — typically 2.5V per cell. At that point the BMS cuts output to prevent damage, and the phone will not respond to the power button. Connect the phone to a wall charger and leave it for 15–20 minutes before attempting to power on; the charge IC needs to push enough current past the lockout threshold before the BMS re-enables the output rail. If the charging indicator does not appear within 30 minutes, measure the battery terminals — a reading below 2.3V means the cell has entered deep discharge and may not recover.
