Repeat Flat Batteries — Solihull emergency jumpstart & Diagnosis
Flat again in Solihull? We measure quiescent current and alternator output before selling anyone another battery. Mobile 24/7 Emergency Jumpstart, 24/7.
A healthy vehicle should draw around 20–50 milliamps once everything has gone to sleep. A faulty module, an aftermarket alarm or a stuck relay can pull ten times that, which flattens a good battery in two or three days.
Solihull at night is quieter than most people think — that means faster response times, not slower. Most emergency jobs on the B90/B91/B92/B93/B94 area are done inside 45 minutes of the call.
We're based in Oldbury, minutes from the M5 and M6, so night response into Solihull is genuinely quick — no waiting until morning like some breakdown clubs.
How a drain is actually traced
- Quiescent draw is measured after the vehicle's modules have gone to sleep, which can take 20–40 minutes — measuring too early gives a false high reading.
- Charge acceptance is tested, because a sulphated battery can read 12.6V and still hold almost no usable energy.
- One dispatcher, one van, one price — no third-party contractor markup like breakdown clubs use
- On a emergency jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
Usage patterns that flatten good batteries
Cars left standing on interwar detached houses for a week or more between uses are the other common case in B90.
Locally that means Solihull itself plus the neighbourhoods that feed into it, with access via M42 J4/J5 and A34 Stratford Road and a practical radius reaching Shirley (~2 mi) and Olton (~2 mi).
Who this page is for
Owners in Solihull on their second or third battery for the same vehicle.
Domestically, interwar detached houses and executive new-builds dominate around here, which shapes how these jobs are accessed and worked.
Drain faults found nearby
Recent job nearby: a car in Solihull on its third battery in two years. Drain measured at 480mA, traced to a boot latch microswitch keeping a module awake.
Recent job nearby: a vehicle off M42 J4/J5 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.

Repeat flat battery questions
Q.What if my car is in a locked car park overnight?
Tell us on the call — usually a security guard or manager can let us in. We've done this in NCPs, hospital car parks and industrial estates dozens of times.
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.
Q.Is a parasitic drain always an electrical fault?
No. Sometimes it is an aftermarket dashcam, tracker or alarm wired to a permanent live. Those are the easy wins and we find them first.
Q.How long does drain testing take?
Allow around an hour. Most of that is waiting for the vehicle's modules to sleep — rushing it produces a meaningless number.
Q.Could short journeys alone be the cause?
Yes, and it is more common than people expect. If that is what the readings show, the fix is a conditioning charge and a change in usage, not another battery.
Q.Do you cover Solihull and the B90 area for this?
Yes. Solihull is inside our routine coverage from Oldbury via M42 J4/J5, roughly 8 miles from Birmingham. We also cover the surrounding neighbourhoods on the same run.
Stop buying batteries. Find the drain.
Proper quiescent current testing in Solihull, with the offending circuit identified rather than guessed. 24/7 Emergency Jumpstart covers interwar detached houses and executive new-builds and trade vehicles alike, all from the same van.

The short version
Repeat failures are solved with a meter, not a parts catalogue. Find the drain, fix the cause, and the next battery lasts its full life. For emergency jumpstart specifically, that means roadside safety kit on board — high-viz, warning triangles, torches, portable jump pack
