Hybrid & EV 12V Battery Faults — Bilton
Bilton 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.
Business account jumpstart and battery replacement across Bilton — priority response, single monthly invoice, no per-job admin, no chasing drivers for card payments.
Account customers get priority slots ahead of retail callouts, so a fleet job on your yard in Bilton won't sit behind three domestic driveway jobs.
Working safely on the 12V side
- AGM is standard for most hybrid auxiliaries and is fitted with the correct venting arrangement where the battery sits inside the cabin or boot.
- Manufacturer jump points are used, which on many hybrids are located away from the battery itself in the engine bay or boot.
- 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.

Why a charged EV can be immobile
Hybrids and EVs are increasingly common on Edwardian villas around Bilton, and 12V auxiliary failures now make up a growing share of our callouts.
Locally that means the streets between Bilton and Rugby, with access via M6 J1 and M45 and a practical radius reaching Rugby (~2 mi) and Bilton (~2 mi).
Areas covered
Working out from CV22, the practical radius for a fleet jumpstart takes in Rugby, Bilton, Hillmorton and Newbold-on-Avon — all within a few minutes of M6 J1.
Owners affected
Drivers told by a breakdown service that the car needs recovering when it needs a 12V battery.
Domestically, Edwardian villas and modern estates dominate around here, which shapes how these jobs are accessed and worked.

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 Bilton and the CV22 area for this?
Yes. Bilton is inside our routine coverage from Oldbury via M6 J1, roughly 2 miles from Rugby. We cover it alongside Rugby and the surrounding streets.
Q.Can you supply and fit batteries at trade price?
Yes — Yuasa, Varta, Bosch and Exide at proper trade rates for account customers, fitted on your yard with OBD coding included.
Q.Do you do preventative fleet audits?
Yes — quarterly on-site checks: voltage, load test, alternator output, terminal condition on every vehicle. Reports emailed to your fleet manager.
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.
Why this is safe to book
- Strict 12V-only working boundary, clearly explained before we start.
- Old batteries removed and recycled on every fleet jumpstart.

The short version
An electric car stopped by a lead-acid battery is a strange idea until it happens to you. In Bilton it is now one of the most common calls we take, and one of the quickest to fix. For fleet jumpstart specifically, that means parasitic drain diagnostics standard — trackers, dashcams, refrigeration, tail-lifts, aftermarket wiring
