Who We Are
BatteryFixes.com is a free EV battery troubleshooting resource built for everyday electric vehicle owners across the United States.
We started this site because we kept seeing the same story play out: an EV owner gets a battery warning, searches online, and ends up either scared by forum horror stories or lost in technical jargon they can’t use. We wanted to fix that.
Our goal is simple — give you clear, honest, practical answers about your EV battery so you can understand what’s happening, decide what to do next, and either fix it yourself or walk into a dealer knowing exactly what to ask.

A Note on Safety
EV high-voltage battery systems operate at 200V to 800V. Some problems on this site require professional service — not because we’re being overly cautious, but because working on high-voltage components without proper training and equipment can be fatal.
We always tell you when a problem is DIY-safe and when it is not. Please read those warnings seriously.
