About this replacement
Huawei Honor 6 Plus — 3.8V Li-Polymer Replacement Battery (HB4547B6EBC)
This 3.8V, 3500mAh (13.3Wh) lithium-polymer cell replaces the original HB4547B6EBC battery in the Huawei Honor 6 Plus and Honor 6 Plus Dual SIM, including variants PE-TL00M and PE-CL00. It fits the same connector footprint and BMS interface as the factory cell. Use the product dimensions — 112.90 × 46.08 × 4.12 mm — to confirm fitment before installing.
- Honor 6 Plus variant coverage: PE-TL00M, PE-CL00, and the Dual SIM variants all share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell covers the full range without modification.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge on the Honor 6 Plus platform. The BMS negotiated charge termination correctly, and the protection circuit tripped as expected at low-voltage cutoff. No anomalous heat or balancing errors were logged.
- First-cycle fuel gauge reset: After installation, disable fast charging and run one complete discharge-to-charge cycle at standard current. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before high-current charging begins on an uncalibrated cell.
Why the Honor 6 Plus reports wrong battery percentage after a cell swap
The phone's fuel gauge IC stores a discharge model calibrated to the original cell. When a new cell goes in, the stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The gauge reads voltage correctly but maps it to the wrong capacity point, so percentages appear inflated or stuck. One full discharge from 100% to automatic shutdown, followed by a full uninterrupted charge, resets the coulomb counter to the new cell's curve.
Sudden shutdown at 20–30% on the replacement cell
This happens when the cell voltage drops below the modem or display's minimum rail voltage under peak load, even though the gauge still reads above zero. The fuel gauge has not yet learned where the new cell's voltage cliff actually sits. Under combined LTE and screen load, current draw spikes and the cell hits cutoff voltage before the gauge catches up. Run two full calibration cycles and the gauge IC will start triggering low-battery warnings closer to the real depletion point.
