12V Battery Dying Repeatedly After Parking?
If your electric vehicle shows a "Charging System Fault" or fails to keep its 12V battery charged after a trip, the DC-DC Converter—which replaces the traditional alternator—may have failed. This is a common issue for EVs left in long-stay parking at Luton, where a deep-discharged 12V battery can stress the converter's startup logic. We provide specialist mobile support to the LU1 area, offering on-site DC-DC system testing, 12V battery health checks, and module resets to ensure you don't get stranded at the terminal.
