Battery Keeps Going Flat in Shirley? Drain Testing & 24/7 Emergency Jumpstart
Flat again in Shirley? We measure quiescent current and alternator output before selling anyone another battery. Mobile 24/7 Emergency Jumpstart, 24/7.
Buying a second battery for the same car in a year is the clearest sign the first one was never the problem. Something is either draining charge while the car sleeps, or failing to put it back while the car runs.
Shirley at night is quieter than most people think — that means faster response times, not slower. Most emergency jobs on the B90 area are done inside 45 minutes of the call.
Long-high-street suburb on the A34 north of Solihull. — at night, that means quiet roads for us and safer waiting for you. We stay on the phone with lone drivers until we arrive.

Usage patterns that flatten good batteries
Cars left standing on 1930s semis for a week or more between uses are the other common case in B90.
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).
How a drain is actually traced
- Charge acceptance is tested, because a sulphated battery can read 12.6V and still hold almost no usable energy.
- Alternator output is checked under electrical load with headlights, blower and heated screen on, not just at idle.
- Priority triage for vulnerable situations: with children, elderly passengers, unsafe locations
- 24/7 Emergency Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.

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.
Who this page is for
Owners in Shirley on their second or third battery for the same vehicle.
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
- We will not sell a battery to a car whose battery is not the fault.
- Old batteries removed and recycled on every emergency jumpstart.
Drain faults found nearby
Recent job nearby: a car in Shirley 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.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 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.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.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.
