It slots into the same battery bay and connects to the same BMS circuit the device expects. Capacity figure is 2250mAh as specified — not inflated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiPAQ 2100 and 2210 platform fit:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell architecture and OEM BMS handshake protocol. The connector pinout and physical dimensions match across the family — 51.95 × 39.26 × 10.80mm — so the cell seats and communicates correctly without adapter modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an iPAQ 2210 and confirmed the BMS accepted the new cell, cleared the low-battery flag, and allowed a clean boot. Charge acceptance was verified from flat to full using the OEM cradle with no error codes thrown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM data preservation before swap:\u003c\/strong\u003e\n    Sync all open files and application state to the host PC before removing the battery. The iPAQ 2100 and 2210 series hold active RAM contents using main battery power — a full power removal without syncing will wipe unsaved data and open application state 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 iPAQ 2210 loses all data after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnlike modern smartphones that store data in flash memory, the iPAQ 2210 keeps active application data and open files in volatile SRAM. That SRAM requires continuous battery voltage to retain its contents. Even a few seconds of zero voltage — during a cell swap — is enough to wipe everything held in RAM. A full ActiveSync backup to a host PC before the swap is the only way to protect that data.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eiPAQ shows charging icon but won't complete a boot after new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe iPAQ boot sequence checks for a minimum threshold voltage before allowing the OS to load. A new cell shipped in storage-safe discharge state can sit too low to pass that threshold. Place the device on the charging cradle for at least 30 minutes before attempting to power on. If the boot still stalls, check cradle contact alignment — oxidised cradle pins cause intermittent charge delivery that mimics a dead cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415952195674,"sku":"BWCS-IP2100XL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415952228442,"sku":"BWCS-IP2100XL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415952261210,"sku":"BWCS-IP2100XL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IP2100XL-1.webp?v=1779758425","url":"https:\/\/batteryweb.com\/products\/hp-ipaq-2212e-replacement-battery-37v-2250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
