About this replacement
Huawei Enjoy 5 / TIT-CL10 — 3.8V Li-Polymer Replacement Battery (HB526379EBC)
This is a 3.8V, 3900mAh (14.82Wh) Li-Polymer cell that replaces the HB526379EBC battery in the Huawei Enjoy 5. It fits the TIT-CL10, TIT-AL00, and Honor Play 5X Dual SIM TD-LTE variants. Swap it in when the original cell can no longer hold a stable charge or causes unexpected shutdowns.
- TIT-CL10 / TIT-AL00 platform fit: These model codes share the same battery bay geometry, flex connector pinout, and BMS handshake protocol. One cell covers all variants on this platform without adapter or modification.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on a TIT-series board. The BMS accepted the cell without fault flags, and the charge IC completed termination at the correct cutoff voltage.
- 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 pushes current into an uncalibrated cell — preventing early percentage drift or premature low-battery warnings.
Sudden shutdown at 20–30% on the replacement cell
This happens when the fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell hits a voltage cliff under modem or display load that the IC wasn't expecting, so it triggers a protective shutdown before the reported percentage reaches zero. It's not a faulty cell — it's a calibration mismatch. Run one full discharge to below 5% without interruption, then charge to 100% uninterrupted, and the IC will remap to the new curve.
USB fast charge not engaging after a cell swap
On the first charge cycle after installation, the charge IC may default to standard 5V/1A input while it evaluates the new cell's impedance profile. This is normal behaviour — the IC runs a brief internal resistance check before allowing elevated current. If fast charge still hasn't engaged after one full cycle, clear the battery stats partition in recovery and attempt a second full cycle from below 10% to 100%.
