It powers the sensor, autofocus system, and image processing stack through the same voltage rail as the OEM BLX-1. Capacity is rated at 11.52Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOM SYSTEM OM-1 and OM-1 Mirrorless compatibility:\u003c\/strong\u003e\n    Both bodies share the same BLX-1 battery bay, connector pinout, and BMS communication protocol — one cell fits either body without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the OM-1 body charger and verified BMS handshake, charge acceptance, and discharge curve across the full capacity range. The BMS logged no rejection flags during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the OM-1:\u003c\/strong\u003e\n    Seat the new cell in the camera body and run one full charge cycle through the body's USB-C port or OEM charger before shooting. The OM-1 BMS maps battery-remaining percentage to the cell's discharge curve during this first cycle — skipping it causes erratic percentage readings on the top-plate LCD.\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 the rated capacity suggests\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OM-1 runs simultaneous loads that most camera bodies don't stack at once — in-body 5-axis stabilisation, stacked sensor readout, phase-detect AF, and the electronic viewfinder all draw current in parallel. Under Starry Sky AF or Pro Capture mode, those loads compound further. A 1600mAh cell rated at camera spec accounts for standard shooting, not sustained multi-system operation. If shot count falls short of expectation, check which drive modes and processing features are active — turning off the EVF in favour of the rear screen alone reduces draw noticeably.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or resetting to 100% mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the OM-1 BMS hasn't yet mapped its voltage thresholds to the replacement cell's discharge curve. The camera ships calibrated to the OEM cell's specific voltage-to-capacity profile, and a new third-party cell needs one full charge-discharge cycle before that mapping aligns. Until it does, the indicator reads off an incorrect lookup table and jumps between percentage steps unevenly. Run one full cycle from 0% to 100% through the camera body — percentage display stabilises after that cycle completes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333606113370,"sku":"BWCS-LXM100MC-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333606146138,"sku":"BWCS-LXM100MC-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333606178906,"sku":"BWCS-LXM100MC-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LXM100MC-1.webp?v=1778212976","url":"https:\/\/batteryweb.com\/products\/olympus-om-system-om-1-replacement-battery-72v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
