CAMILEO H30 Replacement Battery 3.7V 1800mAh Li-ion

CAMILEO H30 / X100 Series — 3.7V Li-ion Replacement Battery

This 3.7V, 1800mAh lithium-ion cell replaces the original battery in the CAMILEO H30, X100, and X100 HD digital cameras. It fits the same physical slot and connector as the factory cell. Capacity is 1800mAh (6.66Wh) — taken from product data, not estimated.

• H30, X100, and X100 HD compatibility: These three models share the same battery bay dimensions, connector pin layout, and 3.7V voltage rail — which is why one cell covers all three. No adapter or modification required.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on camera hardware. The BMS accepted the cell without error flags, and protection circuits tripped correctly at low-voltage threshold — no runaway discharge observed.
• First-install charge cycle: Insert the cell into the camera body and run a full charge via the OEM charger before your first shoot. Some camera BMS systems need one in-body charge cycle to map the new cell's discharge curve correctly for the battery-remaining indicator.

Battery percentage jumping erratically on the H30 display

The H30's battery indicator maps voltage thresholds to percentage steps calibrated to the original cell's discharge curve. A new third-party cell can have a slightly different curve, so the indicator reads one percentage band, then jumps when the voltage crosses the next threshold unexpectedly. This is a display mapping issue — not a fault with the cell itself. One full in-body charge cycle typically allows the BMS to re-calibrate and stabilise the readout.

This happens when the camera's low-voltage cutoff triggers earlier than expected on a freshly installed cell. New lithium-ion cells sometimes rest at a lower open-circuit voltage after storage — the camera interprets this as a depleted battery. Place the cell in the OEM charger until the charge indicator shows full, then re-insert. The camera should clear the low-battery flag once resting voltage is above 3.6V.
