It fits the Pentax Optio S12, Optio S10, and Optio A36 compact digital cameras. Voltage, connector, and physical dimensions match the original — 40.26 × 35.24 × 6.50mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptio S10, S12, and A36 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, 3.7V rail, and D-LI68 connector pinout. The BMS in each body reads cell voltage and temperature from the same contact points, so one battery spec covers all three.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the Optio S12 body. The BMS accepted the cell without rejection flags, and the protection circuit tripped correctly at low-voltage cutoff — no thermal anomalies recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the Optio S12:\u003c\/strong\u003e\n    Charge this battery fully inside the camera body or OEM charger before your first shoot. The Optio S12 BMS maps its battery-remaining display to the discharge curve only after completing one full charge cycle — skipping this step causes erratic percentage readings early on.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling slowing down mid-shoot on the Optio S12\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Optio S12's built-in flash pulls a short, sharp current spike to recharge its capacitor between shots. As cell voltage drops toward the lower end of its discharge curve, that capacitor recharge takes longer — you'll notice the flash-ready indicator lagging. This is normal behaviour tied to available current, not a faulty battery. If recycling time increases noticeably, it's a reliable indicator the cell is below roughly 3.5V and nearing end of charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the Optio S10 or S12 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Optio S10 and S12 map their indicator segments to fixed voltage thresholds calibrated against the original OEM discharge curve. A new replacement cell can have a slightly different mid-range voltage profile, which causes the indicator to jump — dropping two bars quickly, then holding for a long stretch. This is a display mapping issue, not a capacity fault. Run one full charge-to-discharge cycle in the camera body and the indicator will stabilise as the BMS relearns the cell's curve. Check that the battery reads above 3.6V at rest before dismissing a low reading.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333872615514,"sku":"BWCS-NP50FU-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333872648282,"sku":"BWCS-NP50FU-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333872681050,"sku":"BWCS-NP50FU-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP50FU-1.webp?v=1777949432","url":"https:\/\/batteryweb.com\/products\/pentax-optios12-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
