Hybrid & EV 12V Battery Faults — Attleborough
Attleborough hybrid and EV 12V auxiliary battery support. We never touch high-voltage systems — the 12V side is where the fault almost always is.
It surprises people that an electric or hybrid car with a nearly full traction battery can be completely immobile. The high-voltage system cannot close its contactors without the little 12V battery, so a £120 part strands a car with a full charge.
Attleborough at night is quieter than most people think — that means faster response times, not slower. Most emergency jobs on the CV11 area are done inside 45 minutes of the call.
South Nuneaton district on the A4254. — at night, that means quiet roads for us and safer waiting for you. We stay on the phone with lone drivers until we arrive.
Working safely on the 12V side
- Manufacturer jump points are used, which on many hybrids are located away from the battery itself in the engine bay or boot.
- Only the 12V system is touched — the high-voltage traction system is never disturbed.
- Genuine 24/7 — nights, weekends, Christmas Day, New Year — same price as daytime
- On a emergency jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
Why a charged EV can be immobile
Home charging in CV11 does nothing for the 12V battery on many models, which is why owners are caught out despite a full charge.
Locally that means the streets between Attleborough and Nuneaton, with access via M6 J3 and A5 and a practical radius reaching Nuneaton (~1 mi) and Bedworth (~4 mi).

Hybrid and EV questions
Q.I'm on my own and don't feel safe — can you stay on the phone?
Yes — we do this all the time. We'll stay on the line until we arrive, and you can share your live location if that helps.
Q.Is there a night surcharge?
No. Same price at 3am as at 3pm. We think surcharging people who are already stranded is bad business.
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.
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 Attleborough and the CV11 area for this?
Yes. Attleborough is inside our routine coverage from Oldbury via M6 J3, roughly 1 miles from Nuneaton. We cover it alongside Nuneaton and the surrounding streets.
