The WorkPad 8602-20X is an early-2000s pocket computer used for mobile email, scheduling, and data access. It measures 52.63 × 34.07 × 10.41mm and matches the original footprint exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWorkPad 8602-20X platform fit:\u003c\/strong\u003e\n    This cell matches the voltage rail and connector spec of the 8602-20X. The device uses a single Li-ion cell architecture — voltage and physical dimensions both need to match for the BMS to accept the cell and charge correctly.\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 8602-20X platform. The onboard BMS recognised the cell without error flags, and charge termination triggered cleanly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM retention during swap:\u003c\/strong\u003e\n    The WorkPad 8602-20X stores open application state and unsaved data in SRAM powered directly by the main battery. Before removing the old cell, sync all data to your host PC — once power drops, that RAM content is gone permanently.\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 8602-20X loses data on battery removal\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnlike flash-based storage, the WorkPad 8602-20X relies on battery-backed SRAM to hold active application data and system state. The moment the battery is disconnected, that RAM loses power and the data it held is erased. There is no background save that protects open records. Sync to your desktop via HotSync before pulling the cell — that is the only reliable way to protect your data.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWorkPad 8602-20X stuck on boot screen after new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at partial charge — often around 3.0–3.2V — which can fall below the minimum threshold the 8602-20X boot sequence requires. The device may hang on the startup screen or refuse to power on entirely. This is not a fault with the cell. Connect the device to its charger and bring the battery to at least 3.6V before attempting to boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415956619354,"sku":"BWCS-PMIIICSL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415956652122,"sku":"BWCS-PMIIICSL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415956684890,"sku":"BWCS-PMIIICSL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMIIICSL-1.webp?v=1779758481","url":"https:\/\/batteryweb.com\/products\/ibm-workpad-8602-20x-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
