It fits the MS380 and MS380-CUPBGC-SG variants used in retail, warehouse, and logistics pick operations. Voltage and capacity match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMS380 and MS380-CUPBGC-SG compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay, connector pinout, and BMS handshake protocol — one cell covers the full MS380 platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through scan-burst loads and wireless polling draws on the MS380 chassis. The BMS held cutoff correctly at low-cell threshold and accepted a full cradle charge without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle for a complete charge cycle before the first shift. Scan trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents false BMS trips on the first pick run.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle charging error on a freshly installed pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new pack sometimes triggers a charging fault on the cradle dock immediately after installation. The cause is almost always contact resistance — either oxidation on the battery terminals or incomplete seating in the bay. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then press the scanner firmly into the dock until it clicks. If the error clears within 30 seconds, contact resistance was the issue, not the cell itself.\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\"\u003eThe MS380 draws simultaneously from the radio module and the scan trigger during high-frequency barcode reads. When a degraded or low cell can't supply both loads without voltage sag, the radio stack drops its connection before the scanner shows a low-battery warning. If reconnects happen only during burst scanning and not during idle periods, the cell is the source — not the access point or network config. Charge the pack to full and retest; if sag persists above 3.5V under load, the cell needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324850569306,"sku":"BWCS-UMS380BL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324850602074,"sku":"BWCS-UMS380BL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324850634842,"sku":"BWCS-UMS380BL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UMS380BL-1.webp?v=1778123184","url":"https:\/\/batteryweb.com\/products\/unitech-ms380-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
