It fits the Casio Exilim Zoom EX-Z250BE, EX-Z250GD, EX-Z250PK, EX-Z150, and over ten additional Exilim compact models. Swap it in when your original NP-70 no longer holds a full charge or fails to power the camera on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExilim Zoom EX-Z250 and EX-Z150 platform:\u003c\/strong\u003e\n    These compact Exilim bodies share the same NP-70 footprint, voltage rail, and battery-door connector geometry. One cell covers the full range listed above without any adapter or 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 bench. The BMS engaged correctly at both the high-voltage cutoff and the low-voltage floor, and the camera body reported charge state without errors after one full charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle for accurate indicator display:\u003c\/strong\u003e\n    Charge the new cell fully inside the camera body or OEM charger before your first shoot. Some Exilim BMS firmware maps remaining capacity to a voltage curve learned during that initial cycle — skipping it can cause the battery indicator to read inaccurately for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Exilim EX-Z250 shows a dead-battery icon on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EX-Z250's battery indicator maps remaining charge to a fixed voltage lookup table stored in firmware. A new Li-ion cell has a slightly different discharge curve than a worn original, so the camera can misread voltage and flag a low-battery warning even when the cell is at 60–70% capacity. This is not a fault with the replacement cell. One full charge-to-4.2V cycle inside the camera body gives the BMS enough data to re-anchor its threshold mapping. After that cycle, the indicator tracks normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the EX-Z250 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage jumps — say, 80% dropping to 20% in a single shot — point to a voltage-threshold mismatch between the new cell's discharge curve and the camera's indicator firmware. It is most visible in the first few charge cycles on a fresh cell. The fix is to run two or three full discharge-and-recharge cycles: shoot until the camera shuts itself off at the low-voltage cutoff, then charge fully to 4.2V each time. The readings stabilise once the BMS has sampled the new cell's actual voltage behaviour across its full range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333876187226,"sku":"BWCS-NP70CA-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333876219994,"sku":"BWCS-NP70CA-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333876252762,"sku":"BWCS-NP70CA-3","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP70CA-1.webp?v=1778213554","url":"https:\/\/batteryweb.com\/products\/casio-exilim-zoom-ex-z250be-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
