It fits the Ricoh Caplio 400G wide, Caplio G3, Caplio G4, Caplio G4 wide, and six additional Caplio-series models. Same voltage, same connector, same form factor as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCaplio G-series compatibility:\u003c\/strong\u003e\n    These models share the DB-40 footprint and a common 3.7V single-cell power rail. The BMS in each body reads cell voltage directly — no proprietary authentication chip, so a replacement cell with matching voltage and connector seats without handshake friction.\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 charging circuit and confirmed the BMS accepted the cell on first insertion. Charge termination triggered correctly at 4.2V, and the protection circuit tripped at the expected low-voltage cutoff without needing a forced discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on Caplio bodies:\u003c\/strong\u003e\n    Run one complete charge via the camera body or OEM charger before your first shoot. Some Caplio bodies need a full charge cycle from within the camera to calibrate the battery-remaining indicator to the new cell's discharge curve accurately.\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 before the battery indicator drops\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Caplio G-series flash capacitor draws a sharp recharge current burst after each shot. As a Li-ion cell ages or runs low, internal resistance rises and it can't deliver that burst cleanly. The camera body may still show two or three battery bars while the flash visibly lags. This isn't a camera fault — it's the cell's internal resistance limiting peak current output. Swap the battery when flash recycle time extends noticeably, even if the indicator hasn't hit red.\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\"\u003eRicoh's Caplio indicator maps voltage thresholds from the OEM cell's discharge curve. A new third-party cell discharges along a slightly different curve, so the indicator can jump from full to two bars and back within the same shoot. This is a calibration mismatch, not a defective cell. Run two or three full charge-discharge cycles through the camera body to let the BMS remap its thresholds. After conditioning, the display stabilises and tracks remaining charge accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333912658010,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333912690778,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333912723546,"sku":"BWCS-NP60FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP60FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/ricoh-caplio-400g-wide-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
