It replaces OEM part number UP383562A. The flat-cell format matches the original cell at 62.80 × 35.22 × 4.00mm, so it fits the existing battery bay without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWorkPad 8602-10U and c500 compatibility:\u003c\/strong\u003e\n    Both models run the same 3.7V power rail, share the UP383562A cell footprint, and use the same connector pinout — one replacement covers either unit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the WorkPad platform. The BMS held cutoff correctly at low voltage and accepted a full charge without triggering protection faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSync before you swap:\u003c\/strong\u003e\n    The WorkPad holds calendar data, contacts, and open application state in volatile SRAM powered directly by this battery. Pull a full HotSync to your host computer before removing the old cell — anything unsaved to flash will be lost the moment power cuts.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the WorkPad loses all data when the battery goes flat\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe WorkPad c500 and 8602-10U store the active user database — contacts, calendar entries, memos — in SRAM, not flash. SRAM needs a continuous voltage supply to retain data. When the battery discharges fully or is removed without a prior sync, that voltage drops to zero and the RAM contents are wiped. A fresh battery restores power but cannot recover data that was never written to the host. Always HotSync before the battery warning appears, not after.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWorkPad shows the charging screen but won't complete a full boot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA deeply discharged Li-Polymer cell may sit below 3.0V when it arrives or after long storage. The WorkPad boot sequence demands a minimum threshold voltage before it will pass the splash screen. If the device loops on the charging animation or resets immediately on power-up, leave it on charge for 30–60 minutes before attempting to boot. Check that the cell reaches at least 3.6V on the connector before trying again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415957012570,"sku":"BWCS-PM500SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415957045338,"sku":"BWCS-PM500SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415957078106,"sku":"BWCS-PM500SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PM500SL-1.webp?v=1779758425","url":"https:\/\/batteryweb.com\/products\/ibm-workpad-8602-10u-replacement-battery-37v-850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
