Samsung SLB-0937 L830 Replacement Battery 3.7V 650mAh

Samsung L830 / NV4 / PL10 / NV33 — 3.7V Li-ion Replacement Battery (SLB-0937)

This is a 3.7V, 650mAh Li-ion cell built to the SLB-0937 specification. It fits Samsung compact cameras including the L830, NV4, PL10, and NV33. Slide it into the battery compartment and the camera powers on — no modification needed.

• L830 / NV4 / NV33 platform compatibility: These Samsung compact models share the same SLB-0937 footprint, connector orientation, and 3.7V voltage rail. The BMS in each body reads the same charge state signals, so one cell covers the full group.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Samsung compact body. The BMS accepted the cell on first insertion, stepped through charge stages normally, and held voltage within spec at end of charge.
• First-cycle charge protocol for L830 and NV33 bodies: Charge this cell inside the camera body via USB or OEM charger before heavy shooting. Some Samsung compact BMS firmware requires one in-body charge cycle to map the new cell's discharge curve and report battery percentage accurately.

Flash recycling slowing down mid-shoot on the L830

The L830's built-in flash draws a sharp burst of current to recharge its capacitor between shots. As a cell ages — or when a new cell sits at a lower state of charge — internal resistance rises enough to slow that recharge current. The result is a longer wait between flashes, even when the battery indicator still shows charge remaining. If this happens with a fresh cell, charge to 100% in the camera body before shooting in flash-heavy conditions.

Battery percentage jumping erratically on the display

Samsung compact bodies map percentage to a voltage threshold table calibrated against the original cell's discharge curve. A new SLB-0937 replacement may have a slightly different curve at mid-range voltages, causing the indicator to skip or bounce between readings. This is a BMS calibration gap, not a faulty cell. Run one full charge-to-flat cycle inside the camera body and the indicator typically stabilises at the correct readings.
