It fits both the OM SYSTEM OM-1 and OM-1 Mirrorless body variants. Same voltage, same form factor, same connector orientation as the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOM-1 body compatibility:\u003c\/strong\u003e\n    The OM SYSTEM OM-1 runs a single BLX-1 cell at 7.2V. Both listed body variants share the same battery bay dimensions and pin layout — 54.70 x 39.20 x 20.90mm — so one part number covers both. The BMS communicates over the same three-contact interface as the OEM cell.\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 OM-1 body. The BMS accepted the cell without rejection flags, reported charge state correctly after one full charge cycle, and held stable voltage under sustained continuous burst shooting.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the camera body:\u003c\/strong\u003e\n    Charge this battery inside the OM-1 body via USB-C before first use — not in a third-party charger. The OM-1 BMS maps the battery percentage display during a full in-body charge cycle. Skipping this step can cause the indicator to show inaccurate remaining charge 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\"\u003eWhy the OM-1 draws harder than its shot count suggests\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OM-1 stacks several high-draw systems simultaneously — the Quad Bayer stacked sensor, computational processing for subject detection AF, in-body 5-axis stabilisation, and the EVF backlight. Each adds current draw beyond what a single-shot frame count captures. Video recording compounds this further because the processor, sensor, and IBIS all run continuously rather than in short bursts. A 2050mAh cell rated at a specific shot count assumes CIPA test conditions, which don't reflect real mixed-use shooting with AF Tracking and Pro Capture enabled.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or freezing on the OM-1 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS has not completed a full in-body calibration cycle with the new cell. The camera maps its percentage indicator to voltage thresholds it learned from the previous cell's discharge curve. A new cell with a slightly different curve at mid-charge voltages — typically between 7.6V and 7.0V — causes the indicator to skip steps or stall. Fix this by running one complete charge-to-full, then shoot until the camera shuts down at low battery, then charge to full again inside the camera body. After that cycle, the percentage display stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333604180058,"sku":"BWCS-LXM100MU-1","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333604212826,"sku":"BWCS-LXM100MU-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333604245594,"sku":"BWCS-LXM100MU-3","price":68.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LXM100MU-1.webp?v=1778212976","url":"https:\/\/batteryweb.com\/products\/olympus-om-system-om-1-replacement-battery-72v-2050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
