It fits the Caplio RDC-i500, Caplio RR1, RDC-6000, and RDC-7 compact digital cameras. Capacity is 5.18Wh — identical to the OEM spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCaplio series compatibility:\u003c\/strong\u003e\n    The RDC-i500, RR1, RDC-6000, and RDC-7 all share the same DB-20 footprint and 3.7V power rail. The connector orientation, cell dimensions (55.50 × 20.00 × 20.30mm), and BMS voltage thresholds match across this group — no adapters or modifications needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Ricoh camera body charger interface. The BMS handshake completed on first install, charge acceptance was normal, and the cell held voltage within the expected discharge curve under simulated image-capture and LCD draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on Ricoh bodies:\u003c\/strong\u003e\n    Run one full charge cycle through the camera body or OEM charger before heavy shooting. Ricoh's battery-remaining indicator maps voltage thresholds on the first full cycle — skipping this step often causes the display to read inaccurately until the calibration completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the RDC-i500 battery indicator stays stuck or reads full until sudden shutdown\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRicoh's fuel gauge on this camera body uses a voltage-map approach rather than coulomb counting. When a new cell goes in, the camera has no discharge history to reference, so the indicator anchors to a fixed voltage point and stops updating accurately. The display may show full charge until the cell drops below the low-voltage threshold, at which point the camera cuts off without warning. Running one full discharge-recharge cycle through the body resets the voltage map and restores normal indicator behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body showing \"no battery\" with a fully charged replacement cell installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell resting voltage sits outside the window the camera's BMS expects on insertion — typically below 3.6V after shipping or storage. The body interprets a low resting voltage as an absent or dead cell rather than a discharged one. Place the battery in the OEM charger or camera body and allow it to charge to full before powering on. Once the cell reaches 4.2V and the charge cycle completes, the camera body will recognise the battery correctly on next power-on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333870977114,"sku":"BWCS-NP80FU-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333871009882,"sku":"BWCS-NP80FU-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333871042650,"sku":"BWCS-NP80FU-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP80FU_1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/ricoh-caplio-rdc-i500-replacement-battery-37v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
