These are rugged mobile computers used for barcode scanning, inventory control, and data collection across retail and warehouse environments. The cell fits the standard battery bay and connects to the device BMS without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWorkAbout Pro 4 and G4 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V battery rail, physical form factor, and BMS handshake protocol — one cell fits both. The connector orientation and locking tab position are identical across the Pro 4 and G4 variants.\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 and wireless polling loads on a WorkAbout Pro 4 chassis. The BMS handled combined inrush from the imager and radio without tripping into protection mode, and charge acceptance from a standard dock was clean across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for pick-and-pack operations:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its charging cradle for a full charge cycle before putting it on the floor. Scan-trigger inrush current is highest when the cell is near minimum voltage — a fully charged cell prevents false BMS trips during the first high-demand 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 a charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on a fresh battery is almost always a contact resistance issue, not a fault with the cell itself. Dock contacts and the battery terminal pads can accumulate oxidation or debris, raising resistance enough to trigger the dock's protection circuit. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then reseat the pack firmly until the locking tab clicks. If the error clears, the cell was fine — the connection was not.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner dropping wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a fast scan burst, the imager and the wireless radio draw current simultaneously — the combined inrush can pull cell voltage down far enough that the radio module browns out and drops its connection. This happens most often when the battery is below 20% charge, where internal resistance is highest and voltage sag is steepest. The fix is to start shifts with a fully charged pack and replace any cell that reads below 3.5V under load — that threshold is where sag becomes severe enough to affect the radio.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324970958938,"sku":"BWCS-WA3006BL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324970991706,"sku":"BWCS-WA3006BL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324971024474,"sku":"BWCS-WA3006BL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WA3006BL-1.webp?v=1778123453","url":"https:\/\/batteryweb.com\/products\/zebra-workabout-pro-4-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
