All three lights use the same 16340 format cell and share identical voltage and connector requirements. Capacity figure comes from the product specification — 680mAh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBaton 3, Perun Mini, S1R Baton II compatibility:\u003c\/strong\u003e\n    These three lights share the same 16340 cell format, 3.7V nominal voltage rail, and magnetic-charge contact plate. The BMS in each model targets the same charge termination voltage, so one cell specification covers all three 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 Baton 3 driver board. The BMS accepted the cell cleanly, charged via the magnetic port without fault, and stepped down output correctly as voltage dropped toward the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSingle-cell replacement protocol:\u003c\/strong\u003e\n    The Baton 3, Perun Mini, and S1R Baton II each run a single cell — so there is no multi-cell balance issue. However, do not mix this new cell with a partially discharged original in repeated hot-swap cycling. Swap fully when output noticeably drops from a known full charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Baton 3 steps down output before the indicator signals low battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Baton 3 driver runs a brownout protection circuit that cuts output current before the cell voltage actually hits the hard low-voltage cutoff. This is intentional — the driver reads a voltage sag under load and steps down to protect the cell from deep discharge. You will see the light drop from turbo or high to a lower mode while the indicator still shows charge remaining. It is not a fault with the cell. The driver is reading instantaneous load voltage, not resting voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTurbo mode draining the cell noticeably faster than standard or medium\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eTurbo mode on the Baton 3 draws significantly more current than standard or medium modes — often five to ten times the draw. A 680mAh cell handles that current, but the relationship between capacity and runtime is not linear at high draw rates. The cell's internal resistance causes a greater voltage drop under turbo current, which triggers the driver's step-down protection sooner. To extend usable time per charge, switch to high or medium for sustained use and reserve turbo for short bursts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377463558234,"sku":"BWCS-ORS100FT-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377463591002,"sku":"BWCS-ORS100FT-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377463623770,"sku":"BWCS-ORS100FT-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ORS100FT-1.webp?v=1778767154","url":"https:\/\/batteryweb.com\/products\/olight-baton-3-replacement-battery-37v-680mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
