SB-LH82 Samsung Digital Camera Replacement Battery 3.7V 820mAh

Samsung SDC-MS21B / VP-MS10 Series — 3.7V Li-ion Replacement Battery (SB-LH82)

This is a 3.7V, 820mAh Li-ion cell that replaces the Samsung SB-LH82 battery. It fits a range of Samsung compact digital cameras and camcorders, including the SDC-MS21B, SDC-MS21S, VP-MS10, and VP-MS10BL. Dimensions are 44.16 × 31.88 × 7.79mm — a physical match for the original battery compartment.

• SDC-MS21 and VP-MS10 series compatibility: These models share the same SB-LH82 form factor, connector pinout, and 3.7V power rail. The camera BMS reads the same charge thresholds across all listed variants, so one cell covers the full group.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on compatible camera hardware. The BMS accepted the cell without error flags, and charge termination triggered correctly at full voltage.
• First-use charge cycle on these cameras: Charge this battery fully inside the camera body or OEM charger before the first shoot. Samsung's battery-remaining display on these models calibrates its voltage-to-percentage map during that first in-body charge cycle — skipping it can cause the indicator to read inaccurately from the start.

Why the VP-MS10 shows a dead battery icon on a partially charged replacement cell

Samsung's compact camera firmware maps battery percentage against a discharge curve calibrated to the original OEM cell. A new third-party cell has a slightly different open-circuit voltage profile at mid-charge states. The camera reads this as a lower charge level than the cell actually holds, triggering the low-battery icon early. Running one full charge cycle inside the camera body resets the threshold mapping and brings the indicator back into line.

Flash recycling slows and shots stall before the battery indicator drops

The flash capacitor on these Samsung compact models draws a sharp current spike each time it recharges between shots. As cell capacity fades toward end of life, internal resistance rises and voltage sags briefly under that spike. The camera interprets the sag as low power and pauses before allowing the next shot — even when the indicator still shows charge remaining. If recycling lag appears early in the battery's life, check that the cell is fully charged; a half-charged Li-ion cell at 3.7V will show this behaviour under flash load before a fully charged cell at 4.2V will.
