EV 12-Volt Battery Testing

EVs still rely on a small battery. When it fails, it can stop everything.  

While the main high-voltage battery powers the drive system, EVs still use a 12-volt battery for key low-voltage functions such as vehicle access, control modules, lights, safety systems and start-up functions.  

If the 12-volt battery fails, your EV may not unlock, wake up or operate correctly. Battery Town can test your EV’s 12-volt battery and recommend replacement before a small battery issue becomes a major inconvenience.
