Stop-Start Not Working — Shirley emergency jumpstart & Coding
AGM and EFB batteries in Shirley cannot be swapped like an old lead-acid unit. We fit, code and verify on-site. 24/7 Emergency Jumpstart, 24/7 across B90.
AGM and EFB batteries handle far more charge cycles than a standard flooded unit, which is why manufacturers use them — and why they cost more and need proper handling when they fail.
Late shift, night out, early flight — batteries pick the worst moments to die. If you're stranded anywhere from B90 to the M42 J4/J5 we're on it round the clock.
Emergency calls are logged, timestamped and priced up-front. What you pay at 4am is what you'd pay at 4pm — no exploitation.

How start-stop failure shows up first
Newer vehicles are common on 1930s semis around Shirley, so a decent share of our work here involves coding rather than just lifting a battery in and out.
Locally that means the streets between Shirley and Solihull, with access via M42 J4/J5 and A34 Stratford Road and a practical radius reaching Solihull (~2 mi) and Shirley (~2 mi).
Coding, sensors and correct chemistry
- AGM units are tested with an AGM-specific profile, because testing one as flooded lead-acid gives a falsely low reading.
- Memory is maintained during the swap where the vehicle needs it, so radio codes, seat positions and steering angle calibration survive.
- Roadside safety kit on board — high-viz, warning triangles, torches, portable jump pack
- Every emergency jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.
How the visit runs
- 1
Answer + triage
Real person on the phone within seconds, priority given to unsafe situations.
- 2
Coding, sensors and correct chemistry
Where the vehicle uses an intelligent battery sensor on the negative terminal, the sensor is transferred and re-seated correctly rather than forced.
- 3
Confirm + dispatch
Fixed price agreed, van dispatched, live ETA sent by text.
- 4
On-site fix
Jumpstart or replacement carried out on the spot — you're not being told 'come back tomorrow'.
Vehicles and owners affected
Owners of vehicles from roughly 2012 onward across Shirley — the vast majority now run start-stop.
Domestically, 1930s semis and retail-park units dominate around here, which shapes how these jobs are accessed and worked.
Why this is safe to book
- AGM and EFB stock is carried on the van rather than ordered in, so the job finishes on the first visit.
- Old batteries removed and recycled on every emergency jumpstart.
AGM jobs completed nearby
Recent job nearby: a family SUV in Shirley with stop-start inactive for a month. AGM tested at 58% state of health, replaced and registered — stop-start active again on the test drive.
Recent job nearby: a car near M42 J4/J5 on its second battery in 14 months. The previous unit had never been coded, which explained the early failure.
Nearby areas covered
Working out from B90, the practical radius for a emergency jumpstart takes in Solihull, Shirley, Olton and Knowle — all within a few minutes of M42 J4/J5.
AGM and start-stop questions
Q.Do you really answer at 3am?
Yes — a real person answers, not an out-of-hours message service. If we're on a job we call back within minutes.
Q.Why has my stop-start stopped working?
The battery management system disables it when charge acceptance drops. It is a protective measure, and normally the earliest warning of an AGM battery reaching the end of its life.
Q.Can I fit a normal battery instead of an AGM one?
Not on a vehicle designed for AGM. The charging voltage and cycling regime will destroy a standard flooded battery quickly, and stop-start will stay disabled.
Q.Do you code the battery on-site during a emergency jumpstart?
Yes — registration is done in the van with the diagnostic tool before we leave, and we confirm the new profile has taken.
Q.Do you cover Shirley and the B90 area for this?
Yes. Shirley is inside our routine coverage from Oldbury via M42 J4/J5, roughly 2 miles from Solihull. We cover it alongside Solihull and the surrounding streets.
Q.Will you come out in bad weather?
Yes — snow, ice, heavy rain, we still go. Batteries fail more often in bad weather, not less.

Stop-start gone quiet?
That warning is worth acting on. We test with an AGM profile and carry matched stock on the van. 24/7 Emergency Jumpstart covers 1930s semis and retail-park units and trade vehicles alike, all from the same van.
The short version
AGM failure announces itself early through a disabled stop-start function. Testing with the correct profile and coding the replacement is the difference between four years of service and fourteen months. For emergency jumpstart specifically, that means lone-driver phone support: we stay on the line until you're safe or we're on-site
