About this replacement
Wiko RIDE 3 — 3.8V Li-Polymer Replacement Battery (PT34H406082W)
This 3.8V, 3300mAh Li-Polymer cell replaces the original PT34H406082W battery in the Wiko RIDE 3 smartphone. It restores power to calls, messaging, and apps when the original cell can no longer hold a full-day charge. Capacity figures are taken directly from verified product data — 3300mAh at 12.54Wh.
- RIDE 3 fitment: The PT34H406082W footprint is specific to this handset — 80.50 x 59.82 x 3.82mm. The connector pinout and BMS handshake match the RIDE 3 charge IC directly. No adapter or modification needed.
- Bench tested on actual hardware: We ran charge and discharge cycles on this cell and confirmed the BMS communicates correctly with the RIDE 3's fuel gauge IC. Cell voltage held stable across screen-on and modem-active load states.
- First-cycle fast charge tip: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes into an uncalibrated cell.
Why the RIDE 3 reports wrong battery percentage after a cell swap
The RIDE 3 uses a coulomb counter that builds its reference model from the original cell's charge history. When you install a new cell, that reference model is stale and mismatched. The OS reads a percentage based on the old curve, so it can show 40% when the actual cell state is closer to 20%. One full discharge down to auto-shutoff followed by a complete charge to 100% forces the fuel gauge IC to rebuild its lookup table against the new cell's actual characteristics.
Sudden shutdown at 20–30% on the replacement cell
This happens when the modem or display pulls a load spike and the cell voltage drops below the BMS cutoff threshold — even though the gauge still reads 20–30%. It is a fuel gauge calibration issue, not a faulty cell. The BMS sees real terminal voltage collapse while the coulomb counter still reports charge remaining. Run one full uninterrupted cycle — discharge to shutoff, charge to 100% without interruption — and the reported percentage will align with actual cell voltage by the next session.
