It slots into the scanner used across retail, warehouse, and inventory environments where continuous scanning shifts demand a fresh power source. Voltage and capacity match the original cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e9900 platform fit:\u003c\/strong\u003e\n    The 9900 scanner runs a single-cell 3.7V Li-ion architecture. This replacement matches that voltage rail and the physical footprint — 64.94 × 36.80 × 11.80mm — so the cell seats correctly against the contact pads 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 simulated scan-burst loads, monitoring BMS cutoff thresholds at both the low-voltage floor and the inrush spike that the scan trigger generates. The BMS held cutoff within the expected window throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift charging tip:\u003c\/strong\u003e\n    After installing, place the scanner in its cradle for a full charge cycle before use. Scan trigger inrush current is highest when the cell is near minimum. A pre-charged cell prevents false BMS trips on the first shift of the day.\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\"\u003eCharging docks on the 9900 read contact resistance before initiating the charge cycle. If the gold contacts on the battery or cradle have oxidation or handling residue, the dock registers a fault and won't start charging. Remove the battery, wipe both sets of contacts with a dry cloth, and reseat the pack firmly. The dock should begin the charge cycle within a few seconds of correct seating.\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 sequence, the scanner draws current simultaneously from the imager and the wireless radio. This combined inrush can push a partially depleted cell below the BMS protection floor momentarily, dropping the radio link mid-burst. The fix is to ensure the battery is above 3.5V before starting a high-frequency scan session. If dropouts persist at a charged state, check that the battery contact pins in the grip are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324787490906,"sku":"BWCS-DEP750XL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324787523674,"sku":"BWCS-DEP750XL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324787556442,"sku":"BWCS-DEP750XL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEP750XL-1.webp?v=1778123166","url":"https:\/\/batteryweb.com\/products\/david-clark-9900-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
