Olympus Li-60B FE-370 Replacement Battery 3.7V 680mAh

Olympus FE-370 — 3.7V Li-ion Replacement Battery (Li-60B)

This is a 3.7V, 680mAh Li-ion replacement for the Olympus Li-60B battery. It fits the Olympus FE-370 compact point-and-shoot camera. The cell powers the imaging sensor, autofocus motor, flash capacitor, and LCD display.

• FE-370 compatibility: The FE-370 uses the Li-60B form factor — a slim single-cell pack with a three-contact terminal strip. The camera's BMS reads cell voltage across those contacts to gate power delivery to the sensor and display circuits. Physical fit and contact alignment are matched to this model.
• Bench tested on actual hardware: We cycled this cell through the FE-370 body using an OEM charger. The BMS accepted the cell without error flags on the first charge cycle. Voltage at full charge held at 4.19V, and the discharge curve tracked cleanly through the camera's battery-remaining indicator.
• Flash capacitor charging on the FE-370: The FE-370's flash circuit draws a short burst of current to recharge the capacitor between shots. Let the flash-ready indicator fully illuminate before firing again — forcing rapid flash shots on a depleted cell can push the BMS into low-voltage cutoff mid-session.

The FE-370's battery gauge maps voltage thresholds to segment indicators calibrated to the OEM cell's discharge curve. A new third-party cell may sit at 3.85V and still show one bar or a flashing empty icon on first install. This is a gauge mapping mismatch, not a capacity defect. Run one full charge cycle through the OEM charger or the camera's USB port — the BMS recalibrates its threshold reference after a complete charge-to-discharge cycle and the indicator will track correctly from that point.

Battery percentage jumping erratically during a shoot

Erratic percentage jumps — for example, dropping from 60% to 15% then recovering — point to the camera sampling voltage under variable load rather than tracking true state of charge. The FE-370 reads voltage at the terminal contacts; flash recharge spikes and continuous autofocus both cause momentary sag that the indicator interprets as rapid depletion. This typically settles after the first full discharge cycle, once the BMS has mapped the new cell's actual discharge curve. If jumps persist beyond two full cycles, check that the battery contacts in the compartment are clean and making firm contact — debris on the terminals raises internal resistance and exaggerates voltage sag readings.
