Hybrid Won't Power Up in Walsgrave? 12V fleet jumpstart
Walsgrave hybrid and EV 12V auxiliary battery support. We never touch high-voltage systems — the 12V side is where the fault almost always is.
Hybrid and EV 12V batteries live differently to a conventional one: they never see engine cranking, but they are cycled constantly by the vehicle's electronics, and they are often physically small.

Working safely on the 12V side
- Only the 12V system is touched — the high-voltage traction system is never disturbed.
- Once powered, the vehicle's ready state is confirmed and DC-DC converter output is checked to be maintaining the 12V system.
- Priority dispatch for account customers — fleet jobs jump the domestic queue
- On a fleet jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.

Hybrid and EV questions
Q.Is it safe to jump a hybrid?
Yes, at the designated 12V jump points, which are what we use. The high-voltage system is not involved and should never be touched roadside.
Q.Does driving the car charge the 12V battery?
A DC-DC converter maintains it while the car is in ready mode. Short use and long standing still let it sink, exactly as with a conventional car.
Q.Do you cover Walsgrave and the CV2 area for this?
Yes. Walsgrave is inside our routine coverage from Oldbury via M6 J2/J3, roughly 3 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
Q.What if a driver is stranded outside our depot?
That's what account customers get priority for — one call from the driver, we handle it and bill your account, no card payment at the roadside.
Q.How do we open a business account?
One phone call and a fleet list. First job on account can go the same day; formal terms confirmed by email overnight.
Q.My EV has 80% charge — why is it dead?
Because the 12V battery powers the computers that close the high-voltage contactors. Without it, the traction battery cannot be connected to anything.

Full charge, still dead?
That is the 12V auxiliary. On-site testing and replacement across Walsgrave, without touching the high-voltage system. Ask for a fleet jumpstart and quote your postcode — CV2 is a routine run for us.
The short version
The 12V auxiliary is the weak link in hybrids and EVs. Test it, replace it with the right AGM unit, and the car comes back to life without recovery. If you would rather plan it than react to it, a fleet jumpstart can be booked for a time that suits.
