Why Your Battery Keeps Dying — Van Jumpstart, Kings Heath
New battery still going flat in Kings Heath? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus van jumpstart on-site.
Repeat flat batteries are a diagnostic job, not a parts job. The measurement takes longer than the fix usually does.
Van won't turn over in Kings Heath? Nine times out of ten it isn't the starter — it's a tired leisure or main battery that can't hold cranking amps on a cold morning. We come out with a heavy-duty booster rated for diesel commercials.
Around Kings 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.
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.
- Alternator output tested at idle and at 2000 rpm before we leave, so we know the recharge will actually work
- On a van jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Kings Heath — 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 Kings Heath and Birmingham, with access via M6 J6 (Spaghetti Junction) and A38(M) Aston Expressway and a practical radius reaching Birmingham (~4 mi) and Smethwick (~3 mi).
Drain faults found nearby
Recent job nearby: a car in Kings 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 M6 J6 (Spaghetti Junction) flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
Flat again?
Third battery in two years is a diagnosis problem. We measure the draw and the charging output before anything is replaced. Ask for a van jumpstart and quote your postcode — B14 is a routine run for us.

Repeat flat battery questions
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.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.
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 Kings Heath and the B14 area for this?
Yes. Kings Heath is inside our routine coverage from Oldbury via M6 J6 (Spaghetti Junction), roughly 4 miles from Birmingham. We cover it alongside Birmingham and the surrounding streets.
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
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.
- 3
Fixed quote
Price agreed before we set off. Includes callout, jumpstart and full electrical health check.
- 4
On-site test
Voltage, load, alternator output at 2000 rpm, parasitic draw. Real numbers, not guesses.
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 B14.
Where we test
Working out from B14, the practical radius for a van jumpstart takes in Birmingham, Smethwick, Sutton Coldfield and West Bromwich — all within a few minutes of M6 J6 (Spaghetti Junction).

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 Kings Heath 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)
