Fujifilm NP-60 Compatible Battery 3.7V 1050mAh Li-ion

CAMILEO S20 / S20B / S20B HD — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1050mAh lithium-ion cell for the CAMILEO S20, S20B, and S20B HD compact digital cameras. It slots into the same battery compartment as the original cell and powers both image capture and the LCD display. Capacity figures are sourced from our product data, not estimated from third-party specs.

• S20, S20B, and S20B HD compatibility: All three models share the same battery bay dimensions and voltage rail at 3.7V. The connector orientation and cell footprint — 53.20 x 35.30 x 7.10mm — are identical across this camera line, so one cell serves all three variants.
• Bench tested on actual hardware: We cycled this cell through a full charge-discharge sequence and confirmed the BMS accepted charge without tripping protection. Voltage held steady through LCD-on and shutter-active loads with no cutoff events.
• First charge cycle on the S20 body: Insert the new cell and charge it fully inside the camera body before shooting. Some compact camera BMS implementations need one complete in-body charge cycle to map the new cell's discharge curve and show accurate battery-remaining on the LCD.

Why the S20 battery indicator drops suddenly at the end of a charge

The S20 uses a voltage-threshold method to estimate remaining charge rather than coulomb counting. A new cell's discharge curve is steeper in the final 15% compared to a well-used original, so the camera reads voltage dropping fast and jumps the indicator down in one step. This is a display mapping issue, not a cell fault. After one or two full discharge-charge cycles, the indicator settles and tracks more smoothly. If it still reads erratically after three cycles, confirm the cell voltage at rest sits between 3.6V and 4.2V with a multimeter.

Flash recycling slows down before the battery indicator shows low

The flash capacitor draws a high recharge current spike after each shot. As the cell approaches the lower end of its charge, internal resistance rises and the capacitor takes longer to refill — you see a longer pause between flash-ready shots before the battery indicator catches up. This is normal lithium-ion behaviour under high-pulse loads. If recycling time noticeably lengthens, treat it as an early warning that the cell is near its discharge floor, even if the display still shows one bar. Charge the battery when this happens; do not push through multiple additional flash shots at that point.
