These scanners run in retail and warehouse environments where continuous scanning and wireless connectivity put steady demand on the cell. Swap the pack and the scanner returns to full function.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOPR-3301 \/ OPI-3301 platform fit:\u003c\/strong\u003e\n    All four models in this series — OPR-3301, OPI-3301, OPI-3301i, and OPC-3301i — share the same 3.7V single-cell architecture, connector pinout, and BMS communication protocol, which is why one pack covers the entire group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the OPR-3301 platform. The BMS accepted the cell without fault codes, current limiting engaged correctly at the top of charge, and the scanner's scan trigger and wireless radio drew current within normal parameters throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation — OPR-3301 specific:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its cradle and let it complete a full charge cycle before triggering a single scan. The scan trigger inrush current is highest when the cell is near minimum voltage; starting the first shift on a fully charged pack prevents false BMS trips before the cell is conditioned.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OPR-3301 cradle reads pack state through the dock contacts on the battery's lower edge. If those contacts have any film from packaging, skin oils, or residue from the previous battery, the dock interprets the high contact resistance as a fault and throws a charging error — not a pack defect. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the pack firmly until the cradle LED changes state. If the error persists after reseating, check that the cradle is on a stable 5V supply — a voltage drop at the adapter can also trigger this fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner loses wireless connection during a rapid scan burst\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OPR-3301 pulls current for both the imager and the wireless radio simultaneously during a scan burst. When cell voltage sags under that combined load — typically below 3.4V — the radio drops its link before the BMS hard-cuts, causing a connection drop without a visible low-battery warning. This happens most often when the pack is below 20% charge and scan frequency is high. Charge the pack above 3.6V before the shift starts and the voltage sag stays within the radio module's operating floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324867739738,"sku":"BWCS-OPH330BL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324867772506,"sku":"BWCS-OPH330BL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324867805274,"sku":"BWCS-OPH330BL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPH330BL-1.webp?v=1778123334","url":"https:\/\/batteryweb.com\/products\/opticon-opr-3301-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
