It matches the original SL7014 spec and fits the same physical slot without modification. Voltage and capacity are rated at 3.7V \/ 660mAh (2.44Wh) as supplied.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC1200 \/ DC600 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — that is why a single cell covers the full range. The 40.00 × 31.10 × 5.90mm footprint seats flush in all listed bodies.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SeaLife DC1200 body, monitored BMS acceptance on first charge, and confirmed stable voltage delivery across the image sensor and flash capacitor recharge draws. No cutoff events occurred within the rated window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on dive cameras:\u003c\/strong\u003e\n    Insert this cell and charge it fully inside the camera body using the OEM cable before taking it underwater. SeaLife's BMS maps the battery-remaining indicator against its own charge curve — skipping this step causes the indicator to read inaccurately from the first dive.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash capacitor recharge sag on the DC1200 near end of cell charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC1200 flash circuit draws a sharp recharge current burst after each shot. When cell voltage drops toward the lower end of the discharge curve — typically below 3.5V under load — that burst takes longer to complete. The camera body may show the flash-ready indicator more slowly, or the flash may fire at reduced output. This is a load-response behaviour, not a cell fault. If shot-to-shot flash recovery slows noticeably, charge the cell before the next session rather than running it to cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the DC1200 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSeaLife's indicator firmware maps percentage readings against a fixed voltage-threshold table calibrated to the original cell's discharge curve. A new replacement cell may have a slightly different curve shape, so the firmware reads voltage and assigns percentage at different points than expected. This produces jumps — for example, dropping from 80% to 45% in a few shots, then stabilising. Run two full charge-discharge cycles through the camera body. After two cycles the BMS recalibrates its reference points and the display settles to accurate readings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333857509466,"sku":"BWCS-LI40B-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333857542234,"sku":"BWCS-LI40B-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333857575002,"sku":"BWCS-LI40B-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI40B-1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/sealife-dc1200-replacement-battery-37v-660mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
