Logitech G Cloud 533-000213 Compatible Battery 3.85V 5900mAh

Logitech G Cloud — 3.85V Li-Polymer Replacement Battery (533-000213)

This is a 3.85V, 5900mAh Li-Polymer replacement cell for the Logitech G Cloud handheld gaming console. It fits the G Cloud (model numbers 940-000198 and GR0006). Install it when the original cell no longer holds a charge through a full play session.

• G Cloud platform fit: The G Cloud, 940-000198, and GR0006 all share the same battery bay, connector pinout, and BMS handshake protocol — one cell covers all three variants without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a G Cloud unit. The onboard BMS accepted the cell without error flags, and charge termination triggered correctly at full capacity.
• First-cycle fuel gauge reset: After installing, run one complete wireless play session to automatic cutoff before plugging in. The G Cloud's fuel gauge IC sets its empty reference point against the first full discharge — skipping this step causes the indicator to read inaccurately from the start.

Why the G Cloud fuel gauge jumps or reads incorrectly after a cell swap

The G Cloud uses a coulomb-counting fuel gauge IC that tracks charge state against a learned discharge curve from the original cell. A new cell has a different internal resistance profile, so the IC's stored curve no longer matches reality. This causes the percentage readout to jump — often dropping suddenly from 40% to 5%, or stalling at a fixed value. After three to five full discharge-and-charge cycles, the IC re-learns the curve and the readout stabilises.

G Cloud charging slower than expected after battery replacement

The charge IC on the G Cloud applies a conservative current limit when it detects an unconditioned cell — this is a built-in safety behaviour, not a fault with the replacement battery. On the first charge, the IC runs a trickle phase longer than usual before stepping up to full rate. This clears after one complete charge cycle from empty to full. Confirm the charge IC has stepped up by checking that the console body stays only slightly warm — if it stays cold throughout, the IC is still in trickle mode and will advance on the next cycle.
