Battery Keeps Going Flat in Dudley? Drain Testing & Fleet & Business Jumpstart
Flat again in Dudley? We measure quiescent current and alternator output before selling anyone another battery. Mobile Fleet & Business 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.
If your yard in Dudley sees 3+ battery failures a year, you don't need a garage — you need a mobile partner who prices per job on account and turns up before your morning drops leave.
Fleet vans die from parasitic drain more than anything — trackers, dashcams, tail-lifts, refrigeration. We identify the drain, not just recharge the battery.
Drain faults found nearby
Recent job nearby: a car in Dudley 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 A461 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
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.
- Vehicle register held on file — one call gives us the reg, spec, battery history and yard location
- Fleet & Business Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.
Usage patterns that flatten good batteries
Cars left standing on stone-built terraces for a week or more between uses are the other common case in DY1.
Locally that means Dudley itself plus the neighbourhoods that feed into it, with access via A461 and A4123 Birmingham New Road and a practical radius reaching Tipton (~3 mi) and Sedgley (~3 mi).
Repeat flat battery questions
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 Dudley and the DY1 area for this?
Yes. Dudley is inside our routine coverage from Oldbury via A461, roughly 6 miles from Wolverhampton. We also cover the surrounding neighbourhoods on the same run.
Q.How do we open a business account?
One phone call and a fleet list. First job on account can go the same day; formal terms confirmed by email overnight.
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.
Who this page is for
Owners in Dudley on their second or third battery for the same vehicle.

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. That is the whole job: diagnose it properly, fix it once, and explain what caused it.
