⚡ LOW-VOLTAGE FIX
12V Aux Battery Jump
Most "dead EV" calls are not the high-voltage main pack at all - they are a drained 12V accessory battery. We diagnose which one it is before we even arrive, and fix it in minutes.
WHAT'S INCLUDED
Every Call Gets The Full Protocol
WHY IT MATTERS
Built Around EV-Specific Risk
- Two totally different batteries. Every EV has both a large high-voltage main pack and a small 12V accessory battery that runs the electronics — a dead 12V battery mimics a fully dead car.
- Most no-start calls are the small battery. A drained 12V accessory battery is one of the most common reasons an EV won't power on, even with a full main battery charge.
- High-voltage cabling stays untouched. Our techs are trained to jump the 12V system without going anywhere near the orange high-voltage cabling.
COMMON QUESTIONS
Frequently Asked Questions
Most "dead EV" calls turn out to be the small 12V accessory battery, not the high-voltage pack. Tell our dispatcher your symptoms and they can often tell you which one it is before a truck even arrives.
Yes — the jump points and procedure differ by brand, and it's critical to avoid any contact with the high-voltage system. Our techs are specifically trained on EV 12V procedures.
It's possible on some models, but the jump points aren't always obvious and improper technique risks damaging sensitive electronics. Calling it in is safer and often faster.
