Hybrid & EV 12V Battery Faults — Langley
Hybrid or EV dead in Langley with a full traction battery? The 12V auxiliary is the usual culprit. Safe on-site testing and fleet jumpstart.
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.
Fleets working out of the B68 area — courier, plumbing, electrical, HVAC, roofing, letting agents — call us daily. We know your vans, we know your yard, we know when your first drop is.
Account customers get priority slots ahead of retail callouts, so a fleet job on your yard in Langley won't sit behind three domestic driveway jobs.
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.
- Single monthly invoice, VAT-compliant, per-vehicle breakdown ready for your fleet accountant
- 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
Home charging in B68 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 Langley and Oldbury, with access via M5 J2 and A4123 and a practical radius reaching Oldbury (~1 mi) and Langley (~1 mi).
Areas covered
Langley sits about 1 miles from Oldbury, and the same van covers Oldbury (~1 mi), Langley (~1 mi) and Warley (~1 mi) on the same run.
Owners affected
Hybrid and EV owners across Langley whose car will not go to "ready".
Domestically, Victorian terraces and modern estates dominate around here, which shapes how these jobs are accessed and worked.

Hybrid and EV questions
Q.Do you cover Langley and the B68 area for this?
Yes. Langley is inside our routine coverage from Oldbury via M5 J2, roughly 1 miles from Oldbury. We cover it alongside Oldbury 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.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.
Why this is safe to book
- Correct AGM specification with proper venting for boot and cabin installations.
- 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 Langley 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
