The IP3230 is a pocket PC from the early 2000s used for contacts, scheduling, and basic handheld computing. Voltage and capacity match the OEM spec exactly — 3.7V, 4.81Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIP3230 platform fit:\u003c\/strong\u003e\n    The IP3230 runs a single-cell Li-Polymer pack at 3.7V nominal. This cell matches that voltage rail and uses the same connector footprint, so the BMS handshake initialises without error on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the IP3230 platform. The onboard BMS accepted the cell immediately, reported correct state-of-charge, and held voltage above the low-battery cutoff threshold throughout the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSync before you swap:\u003c\/strong\u003e\n    The IP3230 stores open application state and unsaved data in volatile SRAM. That RAM is powered directly by the main battery. Pull the cell without syncing to your host PC first and that data is gone — no recovery path.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the IP3230 loses contacts and calendar entries after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnlike flash-based storage, the IP3230's RAM requires continuous power to hold its contents. Contacts, calendar entries, and app data written to RAM — not the storage card — disappear the moment voltage drops to zero. Even a brief gap during a hot-swap attempt is enough. Before removing the battery, connect to ActiveSync or Windows Mobile Device Center and run a full sync. Anything on the storage card survives; anything in RAM does not.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIP3230 stuck on boot screen after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-Polymer cell shipped from storage may sit below 3.4V. The IP3230's boot sequence checks minimum supply voltage before completing POST, and a depleted cell can stall the device on the splash screen or cause it to reboot in a loop. Connect the device to a charger and leave it for at least 30 minutes before attempting a cold boot. Once the cell reaches approximately 3.6V, the boot sequence completes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415943741530,"sku":"BWCS-IP3230SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415943774298,"sku":"BWCS-IP3230SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415943807066,"sku":"BWCS-IP3230SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IP3230SL-big.webp?v=1779758396","url":"https:\/\/batteryweb.com\/products\/matsunichi-ip3230-replacement-battery-37v-1300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
