It also fits RS-232 configured WDT2200 variants. Same voltage, same form factor, same connector — swap it and go.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWDT2200 and RS-232 fit:\u003c\/strong\u003e\n    Both variants run the same 3.7V single-cell architecture with the same BMS handshake at the dock. One battery covers both configurations without any firmware or connector difference.\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-and-transmit loads. The BMS held charge cutoff at spec and recovered cleanly from low-voltage states without needing a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep on the WDT2200:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and run a full charge cycle before starting pick-and-pack. The scan trigger draws its highest inrush current when the cell is near minimum — a fully charged pack prevents the BMS from tripping on the first heavy scan burst of the 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 charging error on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe WDT2200 cradle reads battery state through the dock contacts. If those contacts have oxidation or debris from the old pack, the dock can misread the new cell and flag a charge error immediately. The charger circuit expects a specific resistance signature at the contact points — anything outside that window throws a fault. Wipe the battery contacts and the cradle pins with a dry cloth, reseat the pack firmly, and the error should clear within one charge handshake cycle.\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 back-to-back scanning, the WDT2200 pulls current simultaneously from the imager and the wireless radio. That combined inrush can drag cell voltage below the radio module's minimum operating threshold, causing the wireless link to drop even though the scanner appears powered. This is more pronounced when the battery is partially discharged. Keep the pack above 3.5V during active shifts — if dropouts are frequent, dock the unit for a partial charge before continuing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324998975578,"sku":"BWCS-WDT220BL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324999008346,"sku":"BWCS-WDT220BL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324999041114,"sku":"BWCS-WDT220BL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WDT220BL-1.webp?v=1778123452","url":"https:\/\/batteryweb.com\/products\/wasp-wdt2200-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
