It restores full charge capacity to scanners that no longer hold a charge through a full diagnostic session. Dimensions are 105.60 x 58.00 x 10.00mm — verify against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD8 and H6 series fit:\u003c\/strong\u003e\n    These models share the same battery bay footprint, connector pinout, and BMS communication protocol — one cell covers the full range without modification.\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 a D8 unit. The BMS accepted the handshake immediately, reported accurate state-of-charge to the scanner's status bar, and triggered the low-voltage cutoff at the correct threshold without false shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-swap data export on the D8:\u003c\/strong\u003e\n    The D8 stores saved vehicle profiles and diagnostic history in memory that draws from the main battery. Cut power before exporting and that data is gone. Go to Settings → Data Management → Export before disconnecting the old cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the D8 won't boot after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-Polymer cell shipped in storage mode can sit below 3.2V — the D8's boot loader requires at least 3.5V to initialise. If the scanner shows nothing on screen after fitting the new battery, it hasn't failed. Connect the OEM charger and leave it for 20–30 minutes before attempting to power on. The BMS will wake the cell from low-voltage lockout and allow the scanner's firmware to load normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWiFi dropping mid-session with the replacement cell fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe D8's WiFi radio draws a short current spike when maintaining an active vehicle connection. If the replacement cell has an internal resistance higher than the original, voltage sags briefly under that load and the radio resets. This shows up as a mid-session disconnect even when the battery indicator reads 60% or above. Check that the connector is fully seated — a loose fit increases resistance at the contact point and makes sag worse.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360120635482,"sku":"BWCS-XTH600SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360120668250,"sku":"BWCS-XTH600SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360120701018,"sku":"BWCS-XTH600SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XTH600SL-1.webp?v=1778610878","url":"https:\/\/batteryweb.com\/products\/xtool-d8-obd2-diagnostic-tool-replacement-battery-38v-10000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
