Erdington Hybrid Auxiliary Battery Help | Fleet & Business Jumpstart
Hybrid or EV dead in Erdington with a full traction battery? The 12V auxiliary is the usual culprit. Safe on-site testing and fleet jumpstart.
The safe boundary matters here. Everything we do is on the 12V side; the orange high-voltage system is left strictly alone.
Running a fleet out of Erdington? A dead battery in one van costs a full day of missed drops, angry customers and a driver stood around. We keep West Midlands fleets moving with priority callout and account billing.
We invoice monthly with full PDF breakdown per vehicle — clean for accounts to file, VAT-compliant, no per-job card fiddling.
Recent hybrid and EV jobs

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.
- 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 1930s semis around Erdington, and 12V auxiliary failures now make up a growing share of our callouts.
Locally that means the streets between Erdington and Birmingham, with access via M6 J6 (Spaghetti Junction) and A38(M) Aston Expressway and a practical radius reaching Birmingham (~4 mi) and Smethwick (~3 mi).
Full charge, still dead?
That is the 12V auxiliary. On-site testing and replacement across Erdington, without touching the high-voltage system. Fleet & Business Jumpstart covers 1930s semis and high-street flats and trade vehicles alike, all from the same van.
Hybrid and EV questions
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.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.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 Erdington and the B23 area for this?
Yes. Erdington is inside our routine coverage from Oldbury via M6 J6 (Spaghetti Junction), roughly 4 miles from Birmingham. We cover it alongside Birmingham and the surrounding streets.
