FOREVER SC-100 Replacement Battery 3.7V 900mAh Li-ion

FOREVER SC-100 / SC-200 Series — 3.7V Li-ion Replacement Battery (S009)

This is a 3.7V, 900mAh Li-ion cell built to the S009 specification, replacing the original battery in the Sanyo SC-100, SC-200, SC-210, and SC-220 digital cameras. The cell matches OEM dimensions at 32.77 × 29.16 × 10.89mm, so it seats correctly in the battery compartment without modification. Voltage and capacity figures are taken directly from product data — not extrapolated.

• SC-100 through SC-220 platform fit: These Sanyo compact cameras share the same battery bay geometry and S009 voltage rail. The BMS in each body reads cell voltage at the same contact points, so one cell specification covers the full model range without adapter or wiring change.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on camera-class test equipment. The BMS handshake completed on first connection, and the protection circuit responded correctly to end-of-discharge cutoff without triggering a false low-voltage lockout.
• First-cycle initialisation on the SC-100: Slot this cell into the camera body and run a full charge via the OEM charger or in-body charging port before your first shoot. Some Sanyo compact bodies recalibrate their battery-remaining indicator during that first in-body charge cycle — skipping it can cause the display to report inaccurate percentages from the start.

Flash recycling lag on a fresh S009 cell

The SC-100's built-in flash draws a short high-current spike to recharge the capacitor between shots. A new cell with a slightly different internal resistance profile can cause the camera to wait longer between flash-ready signals than the original cell did. This is not a fault — it reflects how the BMS meters current during capacitor recharge at different states of charge. The lag typically narrows after the cell has been through two or three full charge-discharge cycles and the BMS has mapped the discharge curve. If recycling time stays long, check that cell voltage after a full charge reads at or above 4.1V.

Battery percentage jumping erratically on the display

The SC-100 maps its battery indicator to voltage thresholds set for the original cell's discharge curve. A replacement cell with a slightly flatter discharge profile can cause the indicator to jump — for example, reading 60% then dropping to 20% within a few frames. The camera body is reacting to voltage steps that don't align with the thresholds it expects. Run two full charge-to-discharge cycles through the camera body and the indicator mapping will stabilise as the BMS learns the new cell's curve. After the second cycle, the display should track smoothly from full to low.
