It fits the DC5890, DC6000, DC6025, DC7000, and 16 additional models in the same family. Physical dimensions are 53.20 × 35.30 × 7.10mm — measure your original cell before ordering if you're unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eJayCam DC-series compatibility:\u003c\/strong\u003e\n    These camera models share the same cell format, connector pinout, and 3.7V voltage rail. The BMS communication protocol is consistent across the DC5890 through DC7000 range, so one cell covers the full group.\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 JayCam-compatible test rigs. The BMS accepted the cell without rejection flags, and voltage held stable across both photo burst and sustained video recording draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charging on compact camera bodies:\u003c\/strong\u003e\n    On first install, run a full charge cycle through the camera body or OEM charger before shooting. Some JAY-tech camera BMS systems need one complete charge cycle to calibrate the battery-remaining display to the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC5890's flash capacitor draws a sharp current spike to recharge between shots. If the cell voltage sags during that spike — common when a cell hasn't been through its first full cycle — recycle time stretches noticeably. This isn't a faulty battery. One full charge-discharge cycle normalises internal resistance and brings capacitor recharge current back to spec. After that cycle, flash recycling should match the original cell's speed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe JayCam body maps its battery indicator to voltage thresholds calibrated for the original cell's discharge curve. A new replacement cell follows a slightly different curve out of the box, so the indicator can skip or stall at certain percentages. This is a BMS mapping issue, not a capacity problem. Run two full charge-discharge cycles inside the camera body and the indicator will stabilise to the new cell's actual curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333911904346,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333911937114,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333911969882,"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\/jay-tech-jaycam-dc5890-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
