Boldmere Hybrid Auxiliary Battery Help | 24/7 Emergency Jumpstart
Boldmere 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.
Late shift, night out, early flight — batteries pick the worst moments to die. If you're stranded anywhere from B73 to the A38 Bassetts Pole we're on it round the clock.
Village-feel southern Sutton suburb on the edge of Sutton Park. — at night, that means quiet roads for us and safer waiting for you. We stay on the phone with lone drivers until we arrive.

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.
- Lone-driver phone support: we stay on the line until you're safe or we're on-site

Hybrid and EV questions
Q.I'm on my own and don't feel safe — can you stay on the phone?
Yes — we do this all the time. We'll stay on the line until we arrive, and you can share your live location if that helps.
Q.Is there a night surcharge?
No. Same price at 3am as at 3pm. We think surcharging people who are already stranded is bad business.
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 Boldmere and the B73 area for this?
Yes. Boldmere is inside our routine coverage from Oldbury via A38 Bassetts Pole, roughly 1 miles from Sutton Coldfield. We cover it alongside Sutton Coldfield and the surrounding streets.
