It fits the Minox DC 1011, DC 1022, DC 8111, and DC 8122 compact digital cameras. Physical dimensions are 41.95 × 36.05 × 9.80mm — match these against your original before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC 1011, DC 1022, DC 8111, DC 8122 compatibility:\u003c\/strong\u003e\n    All four models use the same 3.7V single-cell Li-ion architecture and share the 02491-0028-01 footprint. The connector pinout and BMS communication protocol are identical across the series, so one cell covers the full camera range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on bench equipment to confirm BMS handshake, cutoff voltage behaviour, and that the protection circuit trips correctly before the cell reaches damaging low-voltage thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the camera body:\u003c\/strong\u003e\n    Some Minox compact BMS controllers require the initial charge to happen through the camera body itself — not a standalone charger — to calibrate the battery-remaining display. Complete one full charge cycle via the camera before heavy shooting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the DC 1011 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC 1011's fuel gauge maps voltage thresholds from the original cell's discharge curve. A new replacement cell has a slightly different curve shape — particularly in the mid-range plateau — so the camera's indicator can jump forward or backward by 10–20% as it recalibrates. This is not a faulty cell. Run two or three full charge-to-cutoff cycles through the camera and the indicator will settle. If erratic readings persist beyond three cycles, check that the terminal voltage at full charge reads 4.1–4.2V at the cell contacts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera shows dead battery icon immediately after fitting a charged cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's BMS authentication check does not recognise a new cell on first insertion. It is not a charge problem — the cell can be at full voltage and still trigger this screen. Remove the battery, reinsert it firmly, and power on again. If the icon persists, place the battery in the camera and charge via the USB port or OEM charger until the charge LED confirms a full cycle, then power on. That charge cycle resets the BMS acceptance state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333844729946,"sku":"BWCS-PRD8330-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333844762714,"sku":"BWCS-PRD8330-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333844795482,"sku":"BWCS-PRD8330-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRD8330-1.webp?v=1778213402","url":"https:\/\/batteryweb.com\/products\/minox-dc-1011-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
