It matches the original cell format, connector, and BMS communication spec. Part numbers WA3006, WA3020, WA3025, and 1050494-002 all cross to this pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e7525 \/ 7525C \/ 7527 platform compatibility:\u003c\/strong\u003e\n    These three terminals share the same battery bay geometry, 3.7V single-cell architecture, and BMS handshake protocol — one pack fits across the range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a 7525C unit and cycled it through full charge, scan trigger inrush, and wireless polling loads. The BMS held voltage within spec and did not trip under combined draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and let it complete a full charge cycle before using it in pick-and-pack. Scan trigger inrush current peaks when the cell is near minimum, and a fully charged pack prevents false BMS trips on the first 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  \u003cp class=\"bpw-desc-p\"\u003ePsion cradles read pack state through the battery contacts before initiating a charge cycle. If contact resistance is too high — from dust, oxidation, or an unlocked latch — the dock returns a charging error even when the pack is healthy. Wipe the gold contacts on both the pack and the cradle with a dry cloth, reseat the scanner firmly until the latch clicks, and check that the charge indicator activates. If the error clears within 30 seconds, contact resistance was the cause.\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 7525 draws from the same cell for both the wireless radio and the scan trigger simultaneously. During rapid scan bursts, combined inrush can pull cell voltage below the BMS floor, causing the radio to drop before the scanner itself powers off. This appears as intermittent disconnection rather than a full shutdown. If it happens consistently mid-shift, check that the pack is starting the shift at full charge — 4.2V at the pack terminals — and that the wireless polling interval is not set shorter than necessary in the device config.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324843851866,"sku":"BWCS-WA3006BX-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324843884634,"sku":"BWCS-WA3006BX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324843917402,"sku":"BWCS-WA3006BX-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WA3006BX-1.webp?v=1778123184","url":"https:\/\/batteryweb.com\/products\/psion-7525-replacement-battery-37v-3300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
