It fits the Olympus Camedia AZ-1 and AZ-2 Zoom digital cameras. The cell slots into the same battery compartment as the original and uses the same contact orientation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAZ-1 and AZ-2 compatibility:\u003c\/strong\u003e\n    Both the AZ-1 and AZ-2 Zoom share the same battery bay dimensions and voltage rail. The LI-20B spec covers both — same connector pitch, same 3.7V nominal, same BMS handshake points. No adapters or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a charge and discharge cycle, confirmed BMS cutoff at the correct low-voltage threshold, and verified stable voltage output across the operating range. The cell registered correctly on the battery indicator during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    On first use, insert the cell and run a full charge inside the camera body or OEM charger before shooting. Some Camedia-series BMS firmware maps the battery-remaining display to a discharge curve it calibrates on that first cycle — skipping it can cause the indicator to read inaccurately from day one.\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 replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Camedia series maps its battery-remaining indicator to voltage thresholds calibrated against the original cell's discharge curve. A new third-party cell can sit at a slightly different resting voltage after shipping, causing the camera to misread it as empty. This isn't a fault in the cell — it's a display calibration issue. Insert the battery and charge it fully via the OEM charger or camera body before the first shoot to let the BMS register the new cell's baseline.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during a shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage jumps usually happen when the camera's voltage-to-percentage map doesn't match the new cell's discharge curve. The LI-20B discharge curve drops fairly flat, then falls steeply near depletion — if the camera firmware expects a steeper mid-range drop, it misreads the remaining charge. The fix is one full charge-discharge cycle inside the camera body, which allows the BMS to re-anchor its threshold table to this cell. After that cycle, readings stabilise and the indicator tracks correctly down to the 3.0V cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333908725850,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333908758618,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333908791386,"sku":"BWCS-NP60FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP60FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/olympus-camedia-az-1-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
