These handheld scanners run warehouse, retail, and logistics operations where a dead battery mid-shift costs real time. The OEM part numbers covered are 99EX-BTEC-1 and 99EX-BTES-1.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e99EX and 99GX platform compatibility:\u003c\/strong\u003e\n    Both the 99EX and 99GX share the same battery bay dimensions, connector pin layout, and BMS handshake protocol — a single cell covers the full platform without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the 99EX under combined wireless and scan-trigger load. The BMS held cutoff thresholds correctly at both high-draw bursts and sustained low-draw polling, with no false trips across the test runs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation on cradle-charged devices:\u003c\/strong\u003e\n    After installing a new pack, seat the scanner in its charging cradle and run a full charge cycle before deploying it. Scan-trigger inrush current is highest when the cell sits near minimum charge — starting the shift with a topped-up cell prevents false BMS trips on that first pick-and-pack run.\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\"\u003eThe Dolphin charging cradle reads pack state through spring-loaded dock contacts on the base of the scanner. Oxidation or debris on either the pack contacts or the cradle pins raises contact resistance enough to trigger a charge fault — the dock interprets this as a bad pack rather than a connection issue. Remove the battery, wipe the gold contacts on the pack and the cradle pins with a dry lint-free cloth, then reseat firmly. If the error clears, the cell is fine and the fault was contact resistance, not the battery.\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\"\u003eThe 99EX runs both the imager and the 802.11 radio simultaneously during active scanning. A rapid scan burst pulls inrush current from the imager at the same moment the radio is polling the access point — combined draw can sag cell voltage enough to momentarily drop the wireless stack. This typically surfaces on older or partially degraded packs, but can also appear on a new pack that shipped at storage charge. A full cradle charge before the shift brings cell voltage to the level needed to absorb both loads without sag-induced disconnects.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324833562714,"sku":"BWCS-HY9900BL-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324833595482,"sku":"BWCS-HY9900BL-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324833628250,"sku":"BWCS-HY9900BL-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HY9900BL-1.webp?v=1778123167","url":"https:\/\/batteryweb.com\/products\/dolphin-99ex-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
