It fits the NP-99, R-Hi8, R15, R16, and over 36 additional Ricoh Caplio and GX series models. Voltage, connector, and physical dimensions match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCaplio and GX series compatibility:\u003c\/strong\u003e\n    These models share a common 6V Ni-MH power rail with the same connector housing and BMS voltage thresholds. That shared architecture means 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 full charge and discharge passes on Ricoh body hardware. The BMS accepted the cell without fault flags, and charge termination triggered cleanly at peak voltage delta — no overcharge events recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on Ni-MH:\u003c\/strong\u003e\n    Ni-MH cells ship partially discharged. Run the first charge cycle through the OEM Ricoh charger or camera body rather than a generic charger — the camera's charge controller reads the cell's delta-V curve and sets baseline capacity tracking from that first cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Ricoh Caplio bodies show a dead-battery indicator on a freshly installed replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and Ricoh cameras read a resting voltage below approximately 5.4V as a depleted or missing cell. A replacement shipped months ago can sit right at that threshold. The camera's fuel gauge maps voltage to a percentage scale calibrated to the original cell's discharge curve — a new cell at partial charge will read worse than it actually is. Charge the cell fully before drawing any conclusions about capacity. After one complete charge cycle, the indicator resets and tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the Ricoh display mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's voltage-threshold table doesn't yet have a discharge baseline for the new cell. Ni-MH voltage under load drops steeply, then flattens — if the camera hasn't mapped that curve, percentage readings jump rather than step down smoothly. It's a calibration issue, not a cell fault. Run two full charge-to-discharge cycles and the BMS will track the new cell's curve accurately from around 6.0V down to the 5.2V cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333891293274,"sku":"BWCS-NP55-1","price":35.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333891326042,"sku":"BWCS-NP55-2","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333891358810,"sku":"BWCS-NP55-3","price":45.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP55-1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/ricoh-np-99-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
