It covers the same voltage rail and physical form factor as the original. Capacity is rated at 15.48Wh as measured from the cell, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDR17 and DR-17AA cross-reference:\u003c\/strong\u003e\n    Both part numbers refer to the same cell — same voltage, same connector pinout, same physical envelope. Camera bodies that shipped with either label will accept this battery without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a camera body charger and monitored the BMS handshake across charge and discharge. The protection circuit tripped correctly at low-voltage cutoff and released cleanly on re-charge without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charge on Ni-MH camera cells:\u003c\/strong\u003e\n    Ni-MH cells arrive partially charged from storage. Run one full charge cycle through the camera body or OEM charger before shooting. Some camera BMS systems map the battery-remaining indicator to the discharge curve — they need that first calibration cycle to display an accurate reading.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling slowing down mid-shoot on a fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eFlash capacitor recharge draws a sustained high-current pulse from the battery each time the strobe fires. On a Ni-MH cell, internal resistance rises as the cell approaches the lower third of its charge state — this shows up as longer recycling gaps between flashes before the battery indicator even drops. The camera body sees sufficient terminal voltage to stay on, but the capacitor recharge circuit is starved of peak current. If flash recycling slows noticeably, check terminal voltage under load — anything below 6.0V under draw signals the cell needs a recharge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the camera display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCamera battery indicators are calibrated against a specific discharge curve. A new Ni-MH replacement cell has a flatter mid-range voltage profile than a worn original, so the camera's threshold mapping reads the same state of charge as a different percentage. The indicator can jump from 80% to 40% or stall at a fixed value mid-shoot. Run two full charge-discharge cycles through the camera body and the indicator will stabilise as the BMS recalibrates its reference points against the new cell's curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333848367194,"sku":"BWCS-KLIC011-1","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333848399962,"sku":"BWCS-KLIC011-2","price":48.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333848432730,"sku":"BWCS-KLIC011-3","price":53.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KLIC011-1.webp?v=1778213290","url":"https:\/\/batteryweb.com\/products\/duracell-replacement-battery-72v-2150mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
