It powers the sensor, autofocus system, and electronic viewfinder at the same voltage as the original. Capacity matches the OEM specification at 850mAh (6.12Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1 J5 compatibility:\u003c\/strong\u003e\n    The 1 J5 uses the EN-EL24 form factor — a slim 46.90 × 29.02 × 13.04mm cell with a specific contact layout. This cell matches that footprint and pin arrangement so the door closes and the BMS handshake completes without modification.\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 the 1 J5 body. The BMS accepted the cell after one full charge cycle and reported state-of-charge accurately throughout the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the 1 J5:\u003c\/strong\u003e\n    Charge this cell fully inside the camera body or OEM charger before your first shoot. The 1 J5 BMS maps its battery-remaining indicator against a discharge profile it learns on the first full cycle — skipping this step causes the percentage display to jump erratically early on.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 1 J5 rejects a new EN-EL24 replacement on first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1 J5 runs an authentication check each time a new cell is seated. If the battery hasn't completed a charge cycle through the camera or OEM charger, the body may display an incompatible battery warning even on a valid cell. This is a BMS initialisation issue, not a defective battery. Power cycle the camera once with the cell seated, then charge fully via the body or OEM charger to clear the flag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1 J5 maps its percentage display to voltage thresholds calibrated against its discharge curve. A new replacement cell discharges at a slightly different rate than a worn OEM cell, so the indicator can drop sharply then hold, or jump from 50% to 20% without warning. This is a calibration mismatch, not capacity loss. One full charge-discharge cycle inside the camera body resets the threshold mapping and stabilises the display — charge to 8.4V, shoot until the camera shuts off, then recharge fully.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333703860314,"sku":"BWCS-NKJ150MX-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333703893082,"sku":"BWCS-NKJ150MX-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333703925850,"sku":"BWCS-NKJ150MX-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKJ150MX-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/nikon-1-j5-replacement-battery-72v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
