Samsung WB100 SLB-11A Replacement Battery 3.7V 1050mAh

Samsung WB100 / WB5000 / TL240 Series — 3.7V Li-ion Replacement Battery (SLB-11A)

This is a 3.7V, 1050mAh Li-ion cell built to the SLB-11A form factor. It fits the Samsung WB100, WB1000, WB5000, TL240, and over 30 additional Samsung compact camera bodies that share this battery slot. Voltage and capacity match OEM spec — 3.89Wh total energy.

• WB and TL series compatibility: These Samsung compact models share the same SLB-11A battery rail, connector pinout, and BMS handshake protocol. One cell covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through a WB100 body and a standalone SLB-11A charger. The BMS accepted the cell on first insertion, charge termination triggered correctly at 4.2V, and discharge protection cut in at the expected low-voltage threshold.
• First-use charge cycle on camera body: Run one full charge from inside the camera body or OEM charger before heavy shooting. Samsung's BMS in this series maps the battery-remaining display to the cell's discharge curve — skipping this step causes the indicator to read erratically until the camera calibrates to the new cell.

Flash recycling slowdown on the WB5000 and TL240 as the cell ages

The built-in flash on these cameras pulls a sharp current spike each time the capacitor recharges between shots. As a Li-ion cell ages and internal resistance rises, it delivers that spike more slowly — visible as a longer wait between flash-ready confirmations. A new SLB-11A cell restores the capacitor recharge speed because internal resistance drops back to spec. If recycling is still sluggish on a fresh cell, check the camera's flash capacitor — that points to a body fault, not the battery.

Battery percentage jumping erratically on the WB100 display

This happens when the camera's fuel gauge is mapping its voltage thresholds against the discharge curve of the old, degraded cell it previously calibrated to. A new cell has a flatter mid-range discharge curve, so the indicator misreads state of charge and skips between levels. The fix is one complete charge-to-discharge cycle through the camera body — this lets the BMS re-map its thresholds to the new cell's curve. After that cycle, the percentage readout stabilises and tracks accurately down to the 3.0V cutoff.
