Quick answers, no fluff.
Will a jump start damage modern electronics?+
No. Our jump packs are CAN-bus safe and certified for use on all modern UK vehicles, including hybrids and stop-start systems.
What if the battery is dead beyond reviving?+
We carry replacement batteries in-van. If your battery is finished, we'll quote a transparent replacement price before fitting.
Do you cover EVs?+
We jump-start the 12V auxiliary battery on EVs (yes, EVs have them too). We don't tow or charge the traction battery.
