About this replacement
BlackView A96 — 3.85V Li-Polymer Replacement Battery (LiSP426483SHHTT)
This is a 3.85V, 4350mAh Li-Polymer battery for the BlackView A96 smartphone. It replaces the OEM cell when the original no longer holds adequate charge or fails to charge at all. Capacity matches the factory spec at 16.75Wh.
- A96 cell fit: The A96 uses a pouch-format Li-Polymer cell with a single-cell 3.85V nominal rail. The BMS on this device monitors cell voltage directly — a mismatched cell voltage floor triggers early cutoff. This replacement matches that voltage profile.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the A96 platform. The BMS accepted the cell without fault codes, and the charge IC maintained a stable taper current to the 4.35V termination voltage.
- Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard current. This gives the fuel gauge IC one full reference curve against the new cell before high-current charging begins on an uncalibrated counter.
Sudden shutdown at 20–30% on the replacement cell
This is a voltage cliff issue, not a capacity problem. The fuel gauge IC on the A96 was calibrated to the discharge curve of the old, degraded cell — so its percentage readings no longer map accurately to actual cell voltage. Under modem or display load, the new cell hits the BMS low-voltage cutoff before the gauge reaches 0%. One full discharge to automatic shutoff, followed by a complete charge without interruption, resets the coulomb counter reference points and eliminates the early cutoff.
USB fast charge not activating after replacement
After a cell swap, the charge IC on the A96 may default to standard 5V/1A charging on the first cycle. This happens because the BMS handshake with the charge IC resets when the cell is disconnected — the IC runs a conservative first-cycle profile until it completes one full charge. Plug in, let the device charge uninterrupted to 100%, then unplug and reconnect. Fast charge negotiation should resume from the second cycle onward at the expected voltage step.
