Business account service · Hybrid 12V auxiliary battery
Bromsgrove 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.

We invoice monthly with full PDF breakdown per vehicle — clean for accounts to file, VAT-compliant, no per-job card fiddling.
Recent job nearby: a hybrid in Bromsgrove 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 M5 J4/J4A that had been declared "needs recovery" by another provider. Powered up on the manufacturer jump points in under five minutes.
Hybrids and EVs are increasingly common on market-town centres around Bromsgrove, and 12V auxiliary failures now make up a growing share of our callouts.
Locally that means Bromsgrove itself plus the neighbourhoods that feed into it, with access via M5 J4/J4A and M42 J1 and a practical radius reaching Barnt Green (~3 mi) and Catshill (~2 mi).
Yes. Bromsgrove is inside our routine coverage from Oldbury via M5 J4/J4A, roughly 13 miles from Birmingham. We also cover the surrounding neighbourhoods on the same run.
One phone call and a fleet list. First job on account can go the same day; formal terms confirmed by email overnight.
Yes — we tag your account against your fleet's registered numbers so drivers don't need to authorise every call, and admin still sees one invoice.
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.
Hybrid and EV owners across Bromsgrove whose car will not go to "ready".
Domestically, market-town centres and 1930s semis dominate around here, which shapes how these jobs are accessed and worked.
One call, one fleet list, account live the same day for first callouts.
Driver quotes the fleet reference; no card payment, no per-job admin.
Account jobs go ahead of retail callouts, typical arrival 30–45 minutes.
AGM is standard for most hybrid auxiliaries and is fitted with the correct venting arrangement where the battery sits inside the cabin or boot.
As a district hub, Bromsgrove is covered alongside its surrounding neighbourhoods, so a hybrid 12v auxiliary battery call from any of them routes to the same engineer.
That is the 12V auxiliary. On-site testing and replacement across Bromsgrove, without touching the high-voltage system. We route in via M5 J4/J4A, roughly 13 miles out from Birmingham.
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. Either way you get the readings, the reasoning and a working vehicle before we leave.
