These are compact imaging scanners used in retail point-of-sale and warehouse inventory workflows. Capacity is rated at 2.78Wh and matches the original cell format exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMS5500 \/ MK5502 platform fit:\u003c\/strong\u003e\n    All covered models share the same 3.7V power rail, physical form factor, and BMS handshake protocol — the same cell works across the full scanner family without any modification to the device or firmware.\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 inrush events on the MS5500 chassis. The BMS held the correct cutoff thresholds at both low-state-of-charge and full-charge conditions with no false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation for pick-and-pack use:\u003c\/strong\u003e\n    Place the scanner in its cradle for a full charge cycle before putting it into rotation. Scan trigger inrush current peaks when the cell is near minimum, and starting a shift on a pre-charged pack prevents the BMS from tripping on the first heavy 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 freshly installed pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging docks on the MS5500 family use contact pins that oxidise quickly in warehouse environments. A new pack with clean contacts dropped into a dirty dock can read as an open circuit, triggering a charge fault on the cradle LED. The dock is not detecting the pack — it is detecting the resistance at the contact point. Wipe the battery contacts and dock pins with a dry cloth, reseat the scanner firmly, and the fault clears at contact resistance below roughly 0.5 ohms.\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 MS5500 draws simultaneously from the wireless radio and the imager during a fast scan sequence. When the cell voltage sags under that combined load, the radio module drops its transmission before the imager shuts down — so the scan light stays on but the data never reaches the host. This is a voltage sag issue, not a radio fault. A fully charged pack holds above 3.5V under load and keeps both subsystems stable through burst scanning.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324938322010,"sku":"BWCS-MSP550BL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324938354778,"sku":"BWCS-MSP550BL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324938387546,"sku":"BWCS-MSP550BL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MSP550BL_1.webp?v=1778123428","url":"https:\/\/batteryweb.com\/products\/metrologic-ms5500-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
