It fits the Ricoh Caplio 300G, 400G Wide, 500G, 500G Wide, and more than a dozen additional Caplio-series compact cameras. Slot it into any compatible Caplio body the same way the original ships.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCaplio 300G–500G series compatibility:\u003c\/strong\u003e\n    These cameras share the same 3.7V single-cell architecture, DB-43 contact layout, and BMS handshake protocol — so one cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Caplio body charger and monitored BMS communication at each stage. The protection circuit triggered correctly at low-voltage cutoff and accepted recharge without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle in the camera body:\u003c\/strong\u003e\n    On first use, charge this cell fully via the camera body or OEM charger before shooting. Some Caplio bodies require one in-camera charge cycle to calibrate the battery-remaining display to the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling lag on a new DB-43 cell near end of charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Caplio 300G's flash capacitor pulls a sharp recharge current spike after each shot. As cell voltage drops toward 3.5V, the capacitor takes longer to reach full charge — you'll notice the flash indicator light staying on longer between frames. This isn't a fault with the cell; it's the camera's power management responding to lower available current at the tail of the discharge curve. If recycling lag becomes noticeable, check the battery indicator — at that point the cell is close to cutoff and a recharge is due.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the Caplio display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Caplio series maps voltage thresholds to its battery-remaining indicator using the original DB-43's discharge curve as a reference. A new replacement cell may have a slightly different mid-discharge voltage profile, causing the indicator to skip segments or read higher than expected before dropping suddenly. This is a display calibration issue, not a capacity problem. Run two full charge-to-cutoff cycles in the camera body and the indicator will track more accurately against the new cell's actual curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333867798618,"sku":"BWCS-NP120FU-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333867831386,"sku":"BWCS-NP120FU-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333867864154,"sku":"BWCS-NP120FU-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP120FU-1.webp?v=1778213403","url":"https:\/\/batteryweb.com\/products\/ricoh-caplio-300g-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
