The DC2000 is a compact point-and-shoot built for snorkeling and shallow diving. Swap this cell in when the original no longer holds a full charge between dives.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC2000 platform fit:\u003c\/strong\u003e\n    The DC2000 runs a single-cell 3.7V Li-ion pack at a compact 43.30 × 31.30 × 7.10mm form factor. This cell matches that footprint and voltage rail, so the battery door closes flush and the contacts seat correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the DC2000's charge circuit and monitored BMS handshake behaviour on first insertion. The camera accepted the cell without error flags and the charge indicator progressed normally from empty to full.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-dive charging tip:\u003c\/strong\u003e\n    Rinse and fully dry the camera body before placing it on charge. Salt water residue on the charge port can cause intermittent contact errors that look like a battery fault — dry the port with a cotton swab before connecting the charger.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDC2000 battery percentage jumping erratically after cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC2000's battery indicator is calibrated against the discharge curve of the original cell. A new replacement cell has a slightly different discharge curve, so the camera's voltage-threshold mapping can read the state of charge inconsistently at first. This typically shows as the indicator jumping from 80% to 20% without warning, or sitting at full for longer than expected then dropping fast. Run two full charge-discharge cycles through the camera body and the indicator will re-anchor to the new cell's curve. After conditioning, the display should track within a reasonable band at each voltage step.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a replacement cell that just came off charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSome camera BMS systems perform a voltage authentication check on first insertion and reject a cell that hasn't completed a charge cycle from within the camera's own charge circuit. If the DC2000 shows a depleted battery icon immediately after inserting a freshly charged replacement, do not assume the cell is faulty. Insert the cell into the camera body and charge it via the camera's USB port until the indicator reaches full — this lets the BMS log the cell as accepted. Once that first in-body charge cycle completes, normal operation resumes and the error does not reappear.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333873795162,"sku":"BWCS-SLB10A-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333873827930,"sku":"BWCS-SLB10A-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333873860698,"sku":"BWCS-SLB10A-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SLB10A-1.webp?v=1778213403","url":"https:\/\/batteryweb.com\/products\/sealife-dc2000-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
