It matches the OEM part numbers 50121527-005 and HR-B1. The HR-100 is a portable data capture scanner used in warehouse, retail, and logistics environments.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHR-100 fit and connector:\u003c\/strong\u003e\n    The HR-100 uses a dedicated battery bay with a specific contact layout tied to its BMS handshake. This pack matches that layout — the scanner will not initialise if the contact pitch or cell voltage profile is off.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated scan trigger bursts combined with active wireless polling. The BMS held steady through combined inrush without tripping into protection mode, and cell voltage recovery between bursts was consistent across the test run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for pick-and-pack use:\u003c\/strong\u003e\n    After installing, place the scanner in its cradle for a full charge cycle before going live. Scan trigger inrush current is highest when the cell is near minimum. A fully charged cell prevents false BMS trips at the start of a shift.\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\"\u003eThe HR-100 cradle monitors contact resistance during the charge handshake. If the dock contacts or the battery contacts have any residue or oxidation, the cradle can flag a fault even on a fresh pack. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the scanner firmly. The charge indicator should clear within 30 seconds of a clean connection.\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\"\u003eDuring a rapid scan sequence, the imager and the wireless radio draw current simultaneously. If cell voltage sags under that combined load, the radio stack can drop its connection before the BMS hits its cutoff threshold. This happens most often when the battery is below 30% state of charge. Keep the pack above 3.5V resting voltage during heavy-burst shifts to avoid mid-session dropouts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324845490266,"sku":"BWCS-HY3820BX-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324845523034,"sku":"BWCS-HY3820BX-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324845555802,"sku":"BWCS-HY3820BX-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HY3820BX-1.webp?v=1778123166","url":"https:\/\/batteryweb.com\/products\/keyence-hr-100-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
