Business account service · Hybrid 12V auxiliary battery
Wall Heath hybrid and EV 12V auxiliary battery support. We never touch high-voltage systems — the 12V side is where the fault almost always is.

The safe boundary matters here. Everything we do is on the 12V side; the orange high-voltage system is left strictly alone.
If your yard in Wall Heath sees 3+ battery failures a year, you don't need a garage — you need a mobile partner who prices per job on account and turns up before your morning drops leave.
retail, small business parks, professional services operators in Wall Heath are our regulars — we build a vehicle list against your account so future calls are one text: reg + address.
Recent job nearby: a hybrid in Wall Heath completely unresponsive with a full traction battery. 12V auxiliary read 7.4V — replaced with an AGM unit, ready state confirmed on-site.
Recent job nearby: an EV near A491 that had been declared "needs recovery" by another provider. Powered up on the manufacturer jump points in under five minutes.
Home charging in DY6 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 Wall Heath and Kingswinford, with access via A491 and A4101 and a practical radius reaching Kingswinford (~1 mi) and Wall Heath (~1 mi).
Because the 12V battery powers the computers that close the high-voltage contactors. Without it, the traction battery cannot be connected to anything.
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.
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.
Yes. Wall Heath is inside our routine coverage from Oldbury via A491, roughly 1 miles from Kingswinford. We cover it alongside Kingswinford and the surrounding streets.

As a neighbourhood of Kingswinford, Wall Heath is covered alongside its parent town, so a hybrid 12v auxiliary battery call from any of them routes to the same engineer.
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. Locally this is handled alongside Kingswinford and Wall Heath, so the van is rarely far away.
