The cell measures 40.00 × 31.10 × 5.90mm and seats directly into any NP-80 compatible battery door. Capacity is 660mAh (2.44Wh), matching the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExilim Zoom series fit:\u003c\/strong\u003e\n    The EX-Z1 through EX-Z280 share the same 3.7V single-cell architecture and NP-80 form factor. The battery door latch, contact orientation, and BMS handshake protocol are consistent across this platform, so one cell 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 the EX-Z series body. The BMS accepted the cell without triggering an authentication fault, and the protection circuit engaged correctly at low-voltage cutoff — no hard shutdowns mid-session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the Exilim BMS:\u003c\/strong\u003e\n    Charge this cell fully inside the camera body or OEM charger before your first shoot. The Exilim BMS maps its battery-remaining display to a discharge curve it learns on the first full cycle — skipping this step causes the indicator to jump erratically between readings.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping on the Exilim display after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Exilim BMS uses a voltage-threshold table to estimate remaining charge. A new cell has a slightly steeper discharge curve near the top end compared to a worn OEM cell, so the camera misreads the voltage steps and the displayed percentage jumps or drops suddenly. This is not a fault in the cell — it is the camera recalibrating its internal fuel gauge. Run one complete charge from flat to full without interrupting the cycle. After that first full cycle, the percentage reading stabilises against the actual discharge curve of the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator immediately after fitting a charged replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Exilim bodies show a flat-battery icon on first install of a new cell even when the cell is fully charged. The camera's BMS does not recognise the cell's state-of-charge until it completes one charge cycle from within the body or an OEM-compatible charger. Remove the battery, place it in the OEM charger until the charge indicator confirms full, then reinstall. If the body still shows a dead cell, initiate a charge cycle directly in the camera body — let it run to 4.2V before shooting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333858426970,"sku":"BWCS-LI40B-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333858459738,"sku":"BWCS-LI40B-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333858492506,"sku":"BWCS-LI40B-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI40B-1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/casio-exilim-zoom-ex-z1-replacement-battery-37v-660mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
