It targets retail, warehousing, and logistics scanners where battery wear shows up fast under continuous pick-and-pack cycles. Swap it into any scanner that accepts the 50121527-004 to restore full scan capability.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e50121527-004 platform fit:\u003c\/strong\u003e\n    Honeywell scanners on this battery share a common 3.7V rail, connector format, and BMS handshake. The pack's protection circuit must respond correctly to the scan trigger inrush — a mismatched BMS causes the scanner to cut power to the imager mid-scan.\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 wireless polling loads. The BMS held stable across inrush spikes and did not trip false low-voltage cutoffs during sustained burst sequences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and run a full charge cycle before committing it to a live shift. Scan trigger inrush current peaks when the cell is near minimum charge — starting the first shift on a fully charged pack prevents false BMS trips during the opening burst.\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\n  \u003cp class=\"bpw-desc-p\"\u003eHoneywell cradles check contact resistance before initiating the charge handshake. If the dock or pack contacts carry oxidation or debris, the cradle reads an open circuit and throws a charging fault rather than starting the cycle. This happens most on packs that have been in storage. Wipe the gold contacts on both the pack and cradle with a dry cloth, reseat firmly, and confirm the charge indicator changes state within 30 seconds.\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 burst, the imager and the wireless radio draw current simultaneously. If cell voltage sags under that combined load, the radio module drops off first — the scanner appears to read but the data never transmits. This is a combined inrush problem, not a signal issue. A fully charged 3400mAh pack maintains enough voltage headroom to supply both loads together; check that the pack is above 3.6V before a high-volume scan session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324847063130,"sku":"BWCS-HY3820BX-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324847095898,"sku":"BWCS-HY3820BX-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324847128666,"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\/xenon-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
