About this replacement
HTC Desire V / Desire VC — 3.7V Li-ion Replacement Battery (35H00190-00M)
This is a 3.7V, 1600mAh Li-ion replacement battery for the HTC Desire V, Desire VC, T328W, T328d, and related models. It cross-references OEM part numbers 35H00190-00M, 35H00190-02M, BJ39100, BL11100, and BA S800. Fits the original battery slot without modification.
- Desire V / VC platform fit: The Desire V (T328W) and Desire VC (T328d) share the same battery bay dimensions and connector pinout. Both run off the same 3.7V nominal rail with identical BMS handshake requirements, which is why they share the same OEM part numbers across all three hardware revisions.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on Desire V hardware. The BMS accepted the charge IC handshake without fault flags, held voltage above 3.5V under combined screen and radio load, and tripped protection correctly at the low-voltage cutoff threshold.
- Fuel gauge recalibration after install: On first use, let the phone discharge to automatic shutdown, then charge uninterrupted to 100% before using it again. The Desire V's fuel gauge IC was calibrated to the old cell's discharge curve — one full cycle resets the coulomb counter against the new cell so percentage readings are accurate.
Why the Desire V reports wrong battery percentage after a cell swap
The Desire V uses a coulomb-counter fuel gauge IC that tracks charge state relative to a stored discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry and impedance. The IC continues referencing old data, so the percentage shown on screen drifts from true state of charge. One complete discharge-to-shutdown followed by an uninterrupted charge to 100% forces the IC to relearn the curve against the new cell. After that cycle, percentage accuracy stabilises.
Sudden shutdown at 20–30% remaining on the replacement cell
This happens when the fuel gauge IC has not yet recalibrated and the phone hits the cell's actual voltage cliff before the displayed percentage reflects it. Under combined modem, display, and GPS load, a freshly installed cell can drop voltage faster than the old curve predicts — the hardware voltage cutoff fires at around 3.2V before the OS has a chance to trigger a graceful shutdown. The phone cuts out hard even though the screen showed 25%. Complete one full discharge-charge cycle and the shutdown threshold will align with the displayed percentage.
