Samsung WB210 Replacement Battery BP85A 3.7V 750mAh

Samsung WB210 / SH100 / PL210 — 3.7V Li-ion Replacement Battery (BP85A)

This is a 3.7V, 750mAh Li-ion replacement for the Samsung BP85A battery cell. It fits the WB210, SH100, PL210, and EC-SH100ZBPBUS compact point-and-shoot cameras, along with five additional Samsung models sharing the same form factor and voltage rail. Use it when the original cell no longer holds a full charge or fails to power the camera body.

• WB210 / SH100 / PL210 platform compatibility: These Samsung compact bodies share the same BP85A cell footprint, connector pinout, and 3.7V operating voltage. The BMS on each model communicates over the same contact rail, so one cell covers the full group without modification.
• Bench tested on actual hardware: We cycled this cell through the Samsung WB210 body using the OEM charger. The BMS accepted the cell without fault flags, reported charge state correctly after one full cycle, and held voltage within spec across full discharge at standard camera load.
• First-cycle charging on Samsung compact bodies: Run the first charge from inside the camera body or the OEM Samsung charger — not a generic USB adapter. Samsung's compact BMS maps the battery-remaining indicator during the first charge cycle. Skipping this step causes the indicator to read inaccurately throughout the cell's life.

Flash recharge lag on the WB210 as the BP85A cell ages

The WB210's built-in flash pulls a high burst of current to recharge the capacitor between shots. Early in a cell's life, the internal resistance is low enough that this happens quickly. As the cell ages or if internal resistance is elevated in a replacement cell, capacitor recharge slows — the camera waits longer before allowing the next flash shot. If the ready light is taking noticeably longer than it did on a fresh OEM cell, check the cell's resting voltage: a healthy cell at partial charge should sit above 3.6V. Anything below 3.5V at rest after a recent charge points to elevated internal resistance or a faulty cell.

Battery percentage jumping erratically on the WB210 display

This happens when the camera's fuel gauge hasn't mapped its discharge thresholds to the new cell's actual voltage curve. The OEM firmware uses fixed voltage breakpoints to estimate remaining charge, and a new cell's discharge curve may differ slightly from the original. The result is percentage readings that jump — often from 80% straight to 20% mid-shoot. Fix this by running two full charge-discharge cycles entirely within the camera body. After the second cycle, the BMS recalibrates its threshold mapping and the indicator stabilises.
