Battery Keeps Going Flat in Stourbridge? Drain Testing & Van Jumpstart
Flat again in Stourbridge? We measure quiescent current and alternator output before selling anyone another battery. Mobile Van 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 work van is stone dead around Stourbridge, don't book recovery yet. Most van no-starts near the A491 corridor are cured with a mobile jump and a proper alternator/battery health check on the driveway.
We cover the DY7, DY8, DY9 area regularly for trade customers running Ford Transits, Mercedes Sprinters, VW Transporters, Vauxhall Vivaros, Renault Trafics and Peugeot Boxers.
Drain faults found nearby
Recent job nearby: a car in Stourbridge 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 A491 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
How a drain is actually traced
- Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.
- 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.
- Battery registration/coding done on the OBD for vans that need it (Sprinter, Crafter, T6, Custom)
- Every van jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.
Usage patterns that flatten good batteries
Cars left standing on Georgian townhouses for a week or more between uses are the other common case in DY7.
Locally that means Stourbridge itself plus the neighbourhoods that feed into it, with access via A491 and A458 and a practical radius reaching Wollaston (~1 mi) and Amblecote (~1 mi).
Repeat flat battery questions
Q.Do you cover Stourbridge and the DY7 area for this?
Yes. Stourbridge is inside our routine coverage from Oldbury via A491, roughly 5 miles from Dudley. We also cover the surrounding neighbourhoods on the same run.
Q.Do I need to register a new van battery to the ECU?
On Sprinters, Crafters, T6 Transporters and newer Custom Transits — yes. We carry the OBD tool and code it as part of the fit.
Q.Can you invoice a fleet directly?
Yes — 30-day account terms and single monthly invoice for multi-vehicle operators. Just send us the fleet list.
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.
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, Georgian townhouses and glassworks-era terraces dominate around here, which shapes how these jobs are accessed and worked.

Price agreed before we set off. Includes callout, jumpstart and full electrical health check.
- 3
On-site test
Voltage, load, alternator output at 2000 rpm, parasitic draw. Real numbers, not guesses.
- 4
How a drain is actually traced
Alternator output is checked under electrical load with headlights, blower and heated screen on, not just at idle.
Where we test
Stourbridge sits about 5 miles from Dudley, and the same van covers Wollaston (~1 mi), Amblecote (~1 mi) and Wordsley (~2 mi) on the same run.
Flat again?
Third battery in two years is a diagnosis problem. We measure the draw and the charging output before anything is replaced. Tell us the vehicle and the symptom and you will get a firm price before anyone sets off.

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.
