It fits the 686-5111, 686-5115, 686-5116, 686-5335, and six additional models in the same camera line. Capacity matches the original specification at 21.6Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e686-5111 series compatibility:\u003c\/strong\u003e\n    These models share the same voltage rail, physical connector, and BMS communication protocol. The 12V Ni-MH cell chemistry is consistent across the series, so one battery pack covers the full range 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 a 686-5111 body. The BMS accepted the pack, cell temperature stayed within operating range, and the indicator reported charge state without fault flags throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on camera body:\u003c\/strong\u003e\n    Run the first full charge cycle through the camera body itself, not an aftermarket charger. Some JCpenny camera BMS firmware maps the battery-remaining display to a charge curve it calibrates on that first in-body cycle — skipping this step causes the indicator to read incorrectly from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged BP-122 replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a flatter discharge curve than the lithium chemistry some camera firmware expects. The 686-5111 body may misread remaining charge at certain voltage thresholds, triggering a low-battery warning while the cell still holds usable capacity. This happens because the voltage-threshold map in the BMS was written for a specific discharge profile that doesn't always align precisely with a fresh Ni-MH replacement. Running one full charge-discharge cycle in the camera body allows the BMS to re-map to the actual cell behaviour. After that cycle, the indicator tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots with the new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eFlash recycling draws a high burst of current to recharge the capacitor between shots — this is one of the heaviest loads the camera places on the pack. On a new Ni-MH cell, internal resistance is slightly higher until the cell completes a few charge cycles, which can slow capacitor recharge and cause missed or weak flash output. This is not a fault — it resolves after three to five full charge-discharge cycles as the cell conditions. If recycling lag persists beyond that point, check that the pack voltage at rest reads at least 12V before shooting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333818122330,"sku":"BWCS-VBF2E-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333818155098,"sku":"BWCS-VBF2E-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333818187866,"sku":"BWCS-VBF2E-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VBF2E_1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/jcpenny-686-5111-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
