Hisense U8 Replacement Battery 3.7V 1700mAh LI37163A

Hisense U8 Series — 3.7V Li-ion Replacement Battery (LI37163A)

This is a 3.7V, 1700mAh Li-ion replacement cell for the Hisense U8 and compatible models including the T92, T96, and E920. It replaces OEM part LI37163A when the original cell degrades or fails. The battery restores normal operation for calls, messaging, and apps on devices where the original cell no longer holds a usable charge.

• U8, T92, T96, E920 compatibility: These models share the same battery bay dimensions and connector pinout, and use the same LI37163A cell spec — 58.90 × 46.10 × 5.10mm with a matched 3.7V voltage rail and BMS communication protocol.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the U8 platform. The BMS accepted the cell without error flags, and the charge IC handed off to trickle correctly at the top of the curve.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging for one full discharge-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on an uncalibrated cell.

Sudden shutdown at 20–30% on the Hisense U8 after a cell swap

The Hisense U8 fuel gauge IC retains the discharge curve from the old cell in its coulomb counter after a swap. When the new cell hits a voltage point the IC hasn't mapped yet, it can read 25% remaining while the cell is actually near its cutoff floor. Under screen-on or modem load, the cell voltage drops sharply, crosses the hardware cutoff threshold, and the phone shuts down instantly. One full uninterrupted discharge-charge cycle resets the fuel gauge IC against the new cell's actual curve and eliminates most sudden-shutdown events.

Phone won't power on after the replacement cell sat in storage

Li-ion cells self-discharge in storage, and if the cell voltage drops below approximately 2.5V, the BMS enters a lockout state to prevent damage — the phone shows nothing when you press the power button. Connect the phone to a charger and leave it for 20–30 minutes without attempting to power it on. The charge IC will trickle current into the cell at a low rate until voltage climbs above the BMS recovery threshold, at which point normal charging resumes. If the screen still shows no charging indicator after 45 minutes, verify the cable and adapter are delivering at least 5V before assuming cell failure.
