Battery Keeps Going Flat in Cradley Heath? Drain Testing & Van Jumpstart
Flat again in Cradley Heath? 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.
A dead Transit, Sprinter, Vivaro or Crafter on a B64 driveway usually isn't a garage job. A proper mobile jumpstart with a 2000A+ pack gets you running in minutes without a recovery truck.
Around Cradley Heath the common jobs are morning no-starts on the yard, lunch-break dead batteries at customer sites, and end-of-day flatlines after tail-lift or refrigeration use.
Who this page is for
Owners in Cradley Heath on their second or third battery for the same vehicle.
Domestically, chainmaker-era terraces and canal-side workshops dominate around here, which shapes how these jobs are accessed and worked.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Cradley Heath — a 10-minute trip never replaces the charge that starting consumed, so the battery slowly sinks regardless of health.
Locally that means Cradley Heath itself plus the neighbourhoods that feed into it, with access via A459 and A4100 and a practical radius reaching Old Hill (~1 mi) and Blackheath (~1 mi).
Drain faults found nearby
Recent job nearby: a car in Cradley Heath 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 A459 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.
- Heavy-duty 2000A+ lithium jump pack rated for diesel commercials up to 7.5t
- On a van jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.

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.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 Cradley Heath and the B64 area for this?
Yes. Cradley Heath is inside our routine coverage from Oldbury via A459, roughly 2 miles from Halesowen. We also cover the surrounding neighbourhoods on the same run.
Q.What if the van battery keeps going flat every week?
That's parasitic drain — usually a dashcam, tracker or aftermarket electrics wired to permanent live. We do a milliamp draw test and identify the circuit.
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 van jumpstart.

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.
