It replaces OEM part 02-BATLION-12. The 3101 is a portable data collection terminal used in retail, warehouse, and logistics environments for inventory scanning and wireless data transmission.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3101 and OPR-3101 compatibility:\u003c\/strong\u003e\n    Both the 3101 and OPR-3101 share the same 3.7V cell format, connector pinout, and BMS handshake protocol — this pack covers both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through scan trigger and wireless radio combined-draw scenarios. The BMS held stable through repeated burst events and did not trip on inrush at low state of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle for a full charge cycle before starting a pick-and-pack shift. The scan trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents false BMS trips during the first heavy-use session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on a freshly installed pack is almost always a contact resistance issue, not a fault with the cell itself. The 3101 cradle reads pack status through the dock contacts, and even light oxidation or debris on those contacts breaks the handshake. Wipe the battery contacts and the cradle pins with a dry cloth, then reseat the scanner firmly until you hear it click into position. If the error clears within 30 seconds, contact resistance was the cause — no further action needed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 3101 draws current from two sources simultaneously during a rapid scan burst — the imager and the wireless radio. On a degraded or deeply discharged cell, that combined inrush can pull voltage below the BMS floor, causing a momentary disconnect that looks like a wireless fault. This is not a radio or firmware issue. Charge the pack to full before the shift and keep it above 30% charge during heavy scanning periods. A resting open-circuit voltage of 3.7V or above confirms the cell is not the limiting factor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324957622362,"sku":"BWCS-OPH310BL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324957655130,"sku":"BWCS-OPH310BL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324957687898,"sku":"BWCS-OPH310BL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPH310BL_1.webp?v=1778123452","url":"https:\/\/batteryweb.com\/products\/opticon-3101-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
