It fits the SL50, SL600, ES65, ES70, and over 77 additional Samsung point-and-shoot bodies. Voltage and form factor match the OEM spec exactly — the cell slots into the battery compartment the same way the original does.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSL and ES series compatibility:\u003c\/strong\u003e\n    These Samsung compact lines share the same BP-70A battery bay dimensions, 3.7V nominal voltage rail, and BMS communication protocol. Swapping between models in this family works because the connector orientation and cell geometry are identical across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in an SL50 body through a full charge-discharge cycle. The BMS accepted the cell on first install, reported charge status without error, and held voltage above 3.5V through the bulk of the discharge curve before the low-battery indicator triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on the SL50:\u003c\/strong\u003e\n    Charge this cell in the camera body via USB or OEM charger before your first shoot. Some Samsung compact BMS firmware maps the battery-remaining display against a baseline established during that initial in-body charge — skipping it can cause the indicator to read inaccurately for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SL50 battery percentage jumps erratically with a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's compact camera BMS maps remaining charge against a voltage-threshold table calibrated to the original cell's discharge curve. A new third-party cell discharges along a slightly different curve, so the firmware reads voltage thresholds at the wrong points and jumps the percentage indicator. This typically resolves after two or three full charge-discharge cycles, once the BMS has logged enough data to track the new cell's actual behaviour. If jumping persists beyond three cycles, charge fully to 4.2V via the OEM charger and discharge through normal shooting — not storage mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on the SL50\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe flash capacitor in the SL50 draws a sharp current spike to recharge between shots. When the cell is at low state of charge, internal resistance rises and the voltage sags under that spike — the capacitor doesn't reach full charge before the camera releases the shutter again. The result is visibly dimmer flash output on consecutive shots. This is a cell-state issue, not a camera fault. Charge the battery to full and the recycle behaviour returns to normal; if it doesn't, check the cell rests at or above 3.7V before shooting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333815173210,"sku":"BWCS-BP70A-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333815205978,"sku":"BWCS-BP70A-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333815238746,"sku":"BWCS-BP70A-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP70A-1.webp?v=1778213246","url":"https:\/\/batteryweb.com\/products\/samsung-sl50-replacement-battery-37v-740mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
