Hybrid & EV 12V Battery Faults — Olton
Olton 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 Olton — 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 Olton won't sit behind three domestic driveway jobs.
Why a charged EV can be immobile
Hybrids and EVs are increasingly common on Edwardian semis around Olton, and 12V auxiliary failures now make up a growing share of our callouts.
Locally that means the streets between Olton and Solihull, with access via M42 J4/J5 and A34 Stratford Road and a practical radius reaching Solihull (~2 mi) and Shirley (~2 mi).
Working safely on the 12V side
- Once powered, the vehicle's ready state is confirmed and DC-DC converter output is checked to be maintaining the 12V system.
- AGM is standard for most hybrid auxiliaries and is fitted with the correct venting arrangement where the battery sits inside the cabin or boot.
- Vehicle register held on file — one call gives us the reg, spec, battery history and yard location
- Fleet & Business Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.

Hybrid and EV questions
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.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.
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 Olton and the B92 area for this?
Yes. Olton is inside our routine coverage from Oldbury via M42 J4/J5, roughly 2 miles from Solihull. We cover it alongside Solihull and the surrounding streets.

The short version
An electric car stopped by a lead-acid battery is a strange idea until it happens to you. In Olton it is now one of the most common calls we take, and one of the quickest to fix. If you would rather plan it than react to it, a fleet jumpstart can be booked for a time that suits.
