It fits the Coolpix D7000, D800, D800E, and 28+ additional NiKon DSLR bodies that share this battery format. Voltage and cell chemistry match OEM spec — the BMS on these bodies checks both before reporting charge state.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD7000 \/ D800 platform compatibility:\u003c\/strong\u003e\n    NiKon carried the EN-EL15 connector and voltage rail across multiple DSLR generations — the D7000, D800, and D800E all draw from the same 7V supply path and use the same BMS handshake. One battery format covers a wide production run, which is why so many bodies appear on the fit list.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a D800 body. The BMS accepted the cell after one full charge cycle completed via the OEM charger. Voltage held stable through sustained burst shooting, and the battery-remaining indicator tracked consistently from the second cycle onward.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on NiKon DSLRs:\u003c\/strong\u003e\n    NiKon DSLR bodies calibrate the battery-level display against the charge curve during the first full cycle. Run the first charge to 100% inside the OEM charger or camera body before shooting — this lets the BMS map the new cell's discharge curve and report remaining charge accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the D7000 and D800 show a dead-battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiKon's battery authentication routine reads both voltage and internal resistance at power-on. A new third-party cell has a slightly different resistance profile than a used OEM cell, which can cause the body to report a low or invalid reading on first insertion. This is not a faulty cell — the BMS has not yet mapped the discharge curve. One full charge cycle through the OEM charger or within the camera body resets this. After that cycle, the indicator reports accurately from 100% down to the low-battery cutoff near 6.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the D7000 display mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's fuel gauge is still referencing the old cell's discharge curve after a battery swap. The D7000 maps remaining charge using voltage thresholds calibrated over previous cycles — a new cell with a flatter discharge curve hits those thresholds at different points than expected. The result is the indicator skipping from, say, 60% to 20% without matching actual capacity used. Fully discharge the new cell to near cutoff, then charge to 100% uninterrupted — this forces the BMS to recalibrate its voltage-to-percentage mapping against the actual cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333784076378,"sku":"BWCS-ENEL15MX-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333784109146,"sku":"BWCS-ENEL15MX-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333784141914,"sku":"BWCS-ENEL15MX-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ENEL15MX-1.webp?v=1778213127","url":"https:\/\/batteryweb.com\/products\/nikon-coolpix-d7000-replacement-battery-7v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
