It matches the OEM part number SYWDA64408227 and fits the TC300 form factor directly. Dimensions are 53.12 × 34.04 × 5.68mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTC300 platform fit:\u003c\/strong\u003e\n    The TC300 runs a fixed 3.7V single-cell architecture. This replacement matches that voltage rail and uses the same connector pinout, so the device's power management IC reads cell state correctly without recalibration.\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 a TC300-class load profile. The BMS engaged protection at the correct low-voltage threshold and accepted a full charge without error flags from the device's battery indicator.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-swap sync requirement:\u003c\/strong\u003e\n    Perform a full data sync to the host computer before removing the battery. The TC300 holds open files and application state in RAM powered directly by the main cell — pulling the battery without syncing first will wipe any unsaved data from active sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTC300 not booting after new battery installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly shipped Li-ion cell can arrive at storage voltage — typically 3.6V or lower — which sits below the TC300's minimum boot threshold. The device won't initialise the OS if the cell voltage is too low, and the screen may show nothing or flash briefly before going dark. Connect the TC300 to its charger for at least 30 minutes before attempting the first power-on. Once the cell climbs above 3.7V, the boot sequence completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery capacity draining faster than expected during warehouse scanning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TC300's barcode scanner LED and wireless radio pull significantly more current than the device draws in standby or basic PDA use. Back-to-back scan sessions combined with active Wi-Fi or Bluetooth can deplete a 1000mAh cell much faster than casual use suggests. If capacity seems short, check whether wireless radios are left on between scans — disabling the radio when not syncing reduces draw noticeably. Confirm the cell is reaching a full charge by checking device battery status shows 100% before starting a shift.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415945117786,"sku":"BWCS-TC300SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415945150554,"sku":"BWCS-TC300SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415945183322,"sku":"BWCS-TC300SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TC300SL-1.webp?v=1779758397","url":"https:\/\/batteryweb.com\/products\/t-com-tc300-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
