Mobile van jumpstart · Battery keeps going flat
Why Your Battery Keeps Dying — Van Jumpstart, Friar Park
Flat again in Friar Park? We measure quiescent current and alternator output before selling anyone another battery. Mobile Van Jumpstart, 24/7.
Repeat flat batteries are a diagnostic job, not a parts job. The measurement takes longer than the fix usually does.
If your work van is stone dead around Friar Park, don't book recovery yet. Most van no-starts near the M5 J1 corridor are cured with a mobile jump and a proper alternator/battery health check on the driveway.
Diesel vans need real cranking amps — a jump pack designed for cars won't spin a 2.0 or 2.2 diesel that's been standing cold. Our kit is spec'd for commercials.
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.
- We check tail-lift, refrigeration, dashcam and tracker draw for parasitic drain that kills fleet batteries
- Van Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.
Drain faults found nearby
Recent job nearby: a car in Friar Park 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 M5 J1 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
How the visit runs
- 1
Phone diagnosis
Van make, model, engine size and symptom — we already know if it's a battery, alternator or starter pattern.
- 2
Fixed quote
Price agreed before we set off. Includes callout, jumpstart and full electrical health check.
- 3
How a drain is actually traced
Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.
- 4
On-site test
Voltage, load, alternator output at 2000 rpm, parasitic draw. Real numbers, not guesses.
Usage patterns that flatten good batteries
Cars left standing on post-war estates for a week or more between uses are the other common case in WS10.
Locally that means the streets between Friar Park and West Bromwich, with access via M5 J1 and A41 Expressway and a practical radius reaching West Bromwich (~2 mi) and Oldbury (~2 mi).
Where we test
Working out from WS10, the practical radius for a van jumpstart takes in West Bromwich, Oldbury, Smethwick and Wednesbury — all within a few minutes of M5 J1.

Repeat flat battery questions
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.
Q.Do you cover Friar Park and the WS10 area for this?
Yes. Friar Park is inside our routine coverage from Oldbury via M5 J1, roughly 2 miles from West Bromwich. We cover it alongside West Bromwich and the surrounding streets.

The short version
A battery that keeps dying is telling you about the car, not about itself. Measure the sleep draw and the charging voltage in Friar Park and the real fault usually appears within the hour. For van jumpstart specifically, that means battery registration/coding done on the obd for vans that need it (sprinter, crafter, t6, custom)
