About this replacement
Sony DualShock 4 Wireless Controller — 3.7V Li-ion Replacement Battery (LIP1522)
This is a 3.7V, 1300mAh Li-ion replacement cell for the Sony DualShock 4 Wireless Controller. It fits CUH-ZCT1H, CUH-ZCT1U, CUH-ZCT1E, and related variants that use the OEM part number LIP1522. Swap it in when the original cell no longer holds enough charge to get through a play session.
- CUH-ZCT1 series compatibility: All CUH-ZCT1 variants share the same battery bay dimensions, connector pinout, and charge IC handshake — this cell slots in without modification and communicates correctly with the controller's charge management circuit.
- Bench tested on actual hardware: We ran this cell in a CUH-ZCT1U with rumble and wireless active. The BMS held the charge curve through full cycle without tripping an early cutoff, and the charge IC accepted the cell on the first connection.
- First-cycle calibration on the DualShock 4: After installing, run one complete wireless play session until the controller shuts off automatically — do not plug in early. The DualShock 4 fuel gauge IC sets its empty reference point against the first full discharge cycle, so cutting it short skews the gauge reading for every session after.
Why the DualShock 4 fuel gauge jumps around after a cell swap
The PS4 controller uses a coulomb-counting fuel gauge that tracks charge in and out to estimate remaining capacity. When you fit a new cell, the IC still has discharge curve data mapped to the old, degraded cell. It takes two to three full charge-discharge cycles for the gauge to relearn the new cell's actual voltage-to-capacity curve. Until it does, percentage readings can jump by 20–30 points mid-session. Run three full cycles and the gauge stabilises.
Controller drops wireless connection before the battery indicator hits the last bar
This happens when voltage sags below the wireless radio's operating floor before the on-screen battery icon reflects it. The DualShock 4 combines Bluetooth transmission, motion sensor polling, and rumble motors on the same cell — that combined draw causes a momentary voltage dip the gauge doesn't catch fast enough. A new cell that hasn't completed its conditioning cycles will sag harder under this load. After three to five full charge-discharge cycles, internal resistance drops and the sag narrows. If dropouts persist past five cycles, check that the connector is fully seated — a partial connection adds resistance and worsens sag at the same current draw.
