Battery Keeps Going Flat in Shirley? Drain Testing & Fleet & Business Jumpstart
New battery still going flat in Shirley? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus fleet jumpstart on-site.
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.
Running a fleet out of Shirley? A dead battery in one van costs a full day of missed drops, angry customers and a driver stood around. We keep West Midlands fleets moving with priority callout and account billing.
aerospace, airport services, professional services operators in Shirley are our regulars — we build a vehicle list against your account so future calls are one text: reg + address.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Shirley — a 10-minute trip never replaces the charge that starting consumed, so the battery slowly sinks regardless of health.
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
- 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.
- On-site fleet audits available — we check the whole yard once a quarter and flag ageing batteries before they fail
- Every fleet jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.

Stop buying batteries. Find the drain.
Proper quiescent current testing in Shirley, with the offending circuit identified rather than guessed. We route in via M42 J4/J5, roughly 2 miles out from Solihull.
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
- Findings are written down with the actual current draw in milliamps, so any follow-up work starts from evidence.
- Fixed prices agreed before dispatch — no callout fee just to open the bonnet in B90.
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.
Where we test
Working out from B90, the practical radius for a fleet jumpstart takes in Solihull, Shirley, Olton and Knowle — all within a few minutes of M42 J4/J5.
Repeat flat battery questions
Q.Do you do preventative fleet audits?
Yes — quarterly on-site checks: voltage, load test, alternator output, terminal condition on every vehicle. Reports emailed to your fleet manager.
Q.What if a driver is stranded outside our depot?
That's what account customers get priority for — one call from the driver, we handle it and bill your account, no card payment at the roadside.
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 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.

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. Either way you get the readings, the reasoning and a working vehicle before we leave.
