Olympus Li-10B Stylus 1000 Replacement Battery 3.7V 1090mAh

Olympus Stylus 1000 / u600 / Stylus 800 — 3.7V Li-ion Replacement Battery (Li-10B / LI-12B)

This is a 3.7V, 1090mAh Li-ion cell replacing the Olympus Li-10B and LI-12B batteries. It fits the Stylus 1000, Stylus 600 Digital, u600 Digital, Stylus 800 Digital, and over 37 additional Olympus compact camera models. Slot it into the same battery compartment as the original — same footprint at 46.00 × 31.85 × 9.85mm.

• Cross-model Li-10B / LI-12B platform: Olympus used the same voltage rail and connector pinout across the Stylus and μ (u) compact series from this era. The Li-10B and LI-12B share identical dimensions and a 3.7V nominal rail, which is why one cell fits such a wide model range without any adapter.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on compatible Olympus hardware. The BMS accepted the cell cleanly — no rejection flag, no premature cutoff on the low-voltage protection threshold.
• First-cycle BMS initialisation on Olympus compacts: Run one complete charge via the OEM charger or camera body before heavy shooting. Olympus compact BMS systems map battery-remaining percentage to a known discharge curve — a full initial cycle lets the camera calibrate the indicator accurately against this cell.

Flash recycling lag on the Stylus 1000 with a new replacement cell

The Stylus 1000's flash capacitor draws a sharp recharge current after each exposure. On a fresh cell that hasn't completed a conditioning cycle, the internal resistance is marginally higher than a fully bedded-in cell. This causes a slightly longer gap between the flash-ready indicator appearing and the next shot being available. After two or three full charge-discharge cycles, internal resistance drops and recycling speed normalises. If the lag persists beyond three cycles, check that the battery contacts in the compartment are clean and making solid contact.

Battery percentage jumping erratically on the Stylus display

Olympus compact cameras map the battery icon to fixed voltage thresholds — not to a learned fuel-gauge algorithm. A new cell has a slightly different discharge curve compared to an aged original, so the indicator can leap from full to one bar or skip levels unexpectedly. This is a display calibration issue, not a fault with the cell itself. Complete two full charge cycles inside the camera body and the indicator will track more steadily as the BMS aligns its threshold mapping to the new cell's actual resting voltages — expect around 4.1V at full and 3.5V at cutoff.
