It fits the SG20, SG20B, SG20B1D, SG20B2D, and six additional variants in the SG20 line. It replaces OEM part numbers SGBAT and SG20-BP01 directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSG20 series compatibility:\u003c\/strong\u003e\n    All SG20 variants share the same 3.7V battery bay, connector pinout, and BMS handshake protocol. Swapping between SG20B, SG20B1D, and SG20B2D models does not require reconfiguring the pack — the dock recognises it the same way.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under a combined scan-trigger and wireless polling load. The BMS held voltage within spec through sustained bursts and tripped at the correct low-voltage cutoff without false positives.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing the pack, seat the scanner in its cradle and run a full charge cycle before picking. The scan trigger draws the highest inrush current when the cell is near minimum charge — a depleted pack on the first shift is the most common cause of BMS trips that look like a faulty battery.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThe SG20 cradle uses contact resistance to confirm a valid pack before initiating a charge cycle. If the dock contacts or the battery terminals have any residue from packaging or handling, the cradle reads high resistance and throws a charge error. This is not a fault with the cell itself. Wipe the gold contacts on both the pack and the dock with a dry cloth, reseat the scanner firmly, and the charge indicator should go solid within 10 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 fast scan sequence, the SG20 draws simultaneously from the imager and the wireless radio. This combined inrush can pull voltage down briefly on a cell that is below 3.5V. The radio module is the first subsystem to drop out when voltage sags — the imager keeps firing but the connection drops. Charge the pack to full (4.2V) before a high-frequency scanning shift to keep the voltage rail stable under combined load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324755738714,"sku":"BWCS-ISG200BL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324755771482,"sku":"BWCS-ISG200BL-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324755804250,"sku":"BWCS-ISG200BL-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ISG200BL-1.webp?v=1778123056","url":"https:\/\/batteryweb.com\/products\/intermec-sg20-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
