These units are common in retail stockrooms, distribution centres, and logistics operations where the scanner runs through full shifts on a single charge. The cell matches OEM dimensions at 52.69 × 37.00 × 7.26mm and slots directly into the original battery bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePT40 series platform fit:\u003c\/strong\u003e\n    The PT40, PT40-100, and PT40 PDT share the same battery bay geometry, connector pinout, and BMS handshake protocol — one cell works across all three variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through scan-trigger inrush events and wireless polling loads. The BMS held cutoff correctly at low-voltage threshold and recovered charge acceptance normally through the cradle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-shift charging on the PT40:\u003c\/strong\u003e\n    After installing, place the scanner in its cradle for a full charge cycle before the first pick-and-pack shift. Scan trigger inrush is highest when the cell sits near minimum charge, and starting the shift with a full cell prevents false BMS trips during rapid early-shift scanning.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle charging error on a fresh PT40 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PT40 cradle reads battery state through spring-loaded dock contacts on the base of the scanner. If those contacts have oxidation or debris from warehouse use, the dock reports a charging fault even when the cell is healthy. Wipe the gold contacts on both the battery door and the cradle cup with a dry cloth before reseating. If the error clears after reseating, the cell was never at fault — the contact resistance was high enough to trigger the dock's fault logic.\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\"\u003eOn the PT40, the wireless radio and the scan trigger draw current simultaneously during a fast scan sequence. A depleted or degraded cell can't sustain both loads at once — voltage sags below the radio module's minimum and the connection drops mid-burst. This is not a firmware issue. Charge the replacement cell fully before use and confirm resting voltage reads at least 3.6V before the shift starts. A freshly charged cell handles the combined inrush without the sag that kills the radio link.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324999532634,"sku":"BWCS-WDT220BL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324999565402,"sku":"BWCS-WDT220BL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324999598170,"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\/falcon-pt40-pdt-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
