It matches the OEM form factor and connector orientation, so it seats correctly in the battery compartment without modification. Capacity is drawn directly from product data at 660mAh (2.44Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZ 1650 \/ Z 1655 \/ SZ 125 \/ SZ 10 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, contact spacing, and 3.7V supply rail, which is why one cell covers the full group. The BMS in each body reads cell voltage through the same two-contact interface — no proprietary authentication chip is involved.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on camera-class load equipment, confirming the BMS accepted the cell without rejection flags and that voltage held stable across the mid-discharge curve where most camera shutdowns occur.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the Z 1650:\u003c\/strong\u003e\n    Insert the new cell and run one full charge inside the camera body or OEM charger before your first shoot. Some Maginon bodies calibrate the battery-remaining indicator against a known charge baseline — skipping this step can cause the display to read inaccurately 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\"\u003eBattery percentage jumping erratically on the Z 1650 display\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Maginon Z 1650 maps its battery indicator to a fixed voltage-threshold table calibrated against the original cell's discharge curve. A new replacement cell can follow a slightly different discharge curve — flatter in the mid-range, steeper at the low end — which causes the indicator to skip levels or jump backward. This is a display calibration issue, not a fault with the cell. Run two full charge-to-empty cycles through the camera body and the indicator will stabilise as the BMS accumulates real discharge data for the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera body reads open-circuit voltage at insertion and the new cell's resting voltage sits below the body's acceptance threshold — typically under 3.0V after storage. The fix is straightforward: place the cell in the OEM charger for 15–20 minutes before inserting it into the camera body. Once the cell reaches approximately 3.4V, the body's low-voltage lockout releases and the camera powers on normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333859180634,"sku":"BWCS-LI40B-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333859213402,"sku":"BWCS-LI40B-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333859246170,"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\/maginon-z-1650-replacement-battery-37v-660mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
