These are Windows Mobile PDAs used for email, calendar, contacts, and document viewing. Voltage and capacity match the OEM spec exactly — swap out the degraded cell and restore normal operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e830T and TC600 compatibility:\u003c\/strong\u003e\n    Both devices share the same battery bay geometry, connector pinout, and BMS handshake protocol. The 35H00051-03M part number covers both platforms — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on the 830T and confirmed the BMS accepted the battery without triggering a charge fault. Voltage held stable across standby and active-sync loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM data protection before swap:\u003c\/strong\u003e\n    Sync all open data to a host PC before removing the battery. The Dopod 830T stores active application state and unsaved data in volatile SRAM, which is powered directly by the main battery. A full power removal without syncing first will wipe anything not written to flash storage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Dopod 830T won't boot after a new battery is installed\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 830T boot sequence requires a minimum threshold voltage before the device will attempt to start. A new Li-Polymer cell ships in a partially discharged state — often around 3.4–3.5V — which can sit below that boot threshold. If the device shows nothing when you press power, connect it to the charger for at least 20–30 minutes before attempting to boot. Do not interpret a blank screen as a faulty battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWireless sync dropping or failing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 830T's wireless radio is voltage-sensitive — at charge levels below roughly 3.6V, the radio draws more current than the BMS will sustain, causing the sync to stall or drop mid-transfer. This looks like a driver or software problem but is a power issue. Charge the battery fully to 4.2V before attempting ActiveSync or Bluetooth transfer. A full charge resolves this in most cases.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415950098522,"sku":"BWCS-TC60SL-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43415950131290,"sku":"BWCS-TC60SL-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43415950164058,"sku":"BWCS-TC60SL-3","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TC60SL-big.webp?v=1779758480","url":"https:\/\/batteryweb.com\/products\/dopod-830t-replacement-battery-37v-1200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
