It restores power to the main board and touchscreen so the scanner runs full vehicle diagnostic sessions away from a wall outlet. Dimensions are 105.60 × 58.00 × 10.00mm — measure your existing cell before fitting if you are unsure which variant you have.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH6 Pro and AutoProPAD G2T platform fit:\u003c\/strong\u003e\n    These models share the AHB9858102 cell because they run the same 3.8V main board architecture and use the same five-pin battery connector with integrated BMS handshake. A mismatch on connector pinout will prevent the scanner from reading state-of-charge correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the H6 Pro board and confirmed the BMS reports accurate charge percentage from first boot. The protection circuit tripped correctly at the low-voltage cutoff threshold, preventing cell damage during a simulated deep-discharge event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-swap data export:\u003c\/strong\u003e\n    Export all saved vehicle profiles and ECU data to an SD card or USB before removing the old battery. The H6 Pro stores session data in RAM backed by the main battery — pulling the cell without exporting first will erase unsaved vehicle records.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the H6 Pro loses its wireless link during live data streaming\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe H6 Pro's Bluetooth and Wi-Fi radios draw a combined peak current that spikes sharply during live data streaming from the vehicle ECU. When the battery cell ages and its internal resistance rises, voltage sags under that combined load — the radio subsystem drops first because it sits on a lower-priority power rail than the display and processor. This appears as a sudden disconnect from the vehicle mid-session, even when the battery indicator still shows 30–40%. Replacing the cell with a fresh 10000mAh unit reduces internal resistance and eliminates the sag that triggers the dropout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner screen dims suddenly before the battery indicator shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe H6 Pro's display driver is voltage-sensitive and will throttle backlight output below approximately 3.5V per cell, which can happen under load before the fuel gauge algorithm catches up and flags a low-battery warning. Users see the screen go noticeably darker mid-session while the status bar still reads 20% or higher. This is a cell-voltage sag issue, not a display fault. Charge the replacement battery to full before the first diagnostic session and confirm the scanner boots with the battery indicator above 3.7V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360120537178,"sku":"BWCS-XTD900SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360120569946,"sku":"BWCS-XTD900SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360120602714,"sku":"BWCS-XTD900SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XTD900SL-1.webp?v=1778610878","url":"https:\/\/batteryweb.com\/products\/xtool-h6-pro-replacement-battery-38v-10000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
