It fits the DC 6311, DC 4211, DC 5222, and DC 6011. Dimensions are 43.70 × 31.30 × 7.00mm — the same footprint as the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC 6311, DC 4211, DC 5222, DC 6011 compatibility:\u003c\/strong\u003e\n    These four models share the same battery bay geometry, NP-900 connector pinout, and 3.7V voltage rail. One cell works across all four bodies 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 charge and discharge on the DC 6311 body. The BMS accepted the cell on the first charge cycle and reported remaining capacity without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on DC series bodies:\u003c\/strong\u003e\n    Insert the battery and charge it fully inside the camera body before shooting. Minox DC series firmware maps the battery-remaining indicator against a charge curve logged during the first in-body cycle — skipping this step causes the indicator to read erratically from the start.\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 on the DC 6311 display after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC 6311 maps its battery indicator against voltage thresholds calibrated to the original cell's discharge curve. A new replacement cell has a slightly different curve at mid-charge, which causes the indicator to skip readings or drop suddenly between shots. This is a display calibration issue, not a cell fault. Run one full in-body charge cycle from flat to full and the firmware re-maps to the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not recycling fully between shots near end of charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe flash capacitor on the DC 6311 draws a sharp recharge current after each shot. When cell voltage drops below approximately 3.5V under load, that recharge current sags and the capacitor does not reach full charge before the next frame. The result is visibly dimmer flash output or a longer-than-normal ready light delay. If flash output drops noticeably, check cell voltage under load — at or below 3.4V the cell needs recharging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333833818202,"sku":"BWCS-NP900-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333833850970,"sku":"BWCS-NP900-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333833883738,"sku":"BWCS-NP900-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP900-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/minox-dc-6311-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
