Both models run on the same 3.6V single-cell architecture and share the same OEM part numbers: 20-16228-07 and 20-16228-09. Capacity is 1800mAh (6.48Wh) — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWT2200 and WT2280 compatibility:\u003c\/strong\u003e\n    Both scanner variants use identical battery bays, connector pinouts, and BMS handshake logic. The same cell fits both without modification or adapter — the voltage rail and communication lines are shared across the series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the WT2200's charge management circuit and confirmed the BMS accepted the cell without fault flags. Charge termination and over-discharge cutoff both triggered at expected thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its charging cradle and run a full charge cycle before use on the floor. Scan trigger inrush current peaks when the cell is near its minimum voltage — a fully charged pack prevents false BMS trips during the first pick-and-pack shift.\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\"\u003eA charging error on a freshly installed battery usually points to contact resistance between the pack terminals and the cradle's charging pins, not a fault with the cell itself. Oxidation or debris on either surface breaks the low-voltage handshake the cradle uses to begin the charge cycle. Wipe the battery contacts and cradle pins with a dry cloth, reseat the scanner firmly, and check that the pack is flush in the bay. The charge indicator should clear within 30 seconds of a clean connection.\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 WT2200 draws simultaneously from the wireless radio and the scan trigger — two inrush loads hitting the cell at the same time. If the battery is aged or sitting at a low state of charge, the combined draw causes a brief voltage sag that the BMS reads as an unsafe drop, momentarily cutting output and dropping the wireless link. This is not a radio fault — it is the BMS protecting the cell. Start each shift with a fully charged pack and the connection drops should stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43325021421658,"sku":"BWCS-WT2200-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43325021454426,"sku":"BWCS-WT2200-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43325021487194,"sku":"BWCS-WT2200-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WT2200_1.webp?v=1778123493","url":"https:\/\/batteryweb.com\/products\/chameleon-rf-wt2200-replacement-battery-36v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
