Why Your Battery Keeps Dying — Van Jumpstart, Tile Hill
New battery still going flat in Tile Hill? 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 Tile Hill? 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.
We cover the CV4 area regularly for trade customers running Ford Transits, Mercedes Sprinters, VW Transporters, Vauxhall Vivaros, Renault Trafics and Peugeot Boxers.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Tile Hill — 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 Tile Hill and Coventry, with access via M6 J2/J3 and M69 and a practical radius reaching Coventry (~4 mi) and Nuneaton (~9 mi).

Stop buying batteries. Find the drain.
Proper quiescent current testing in Tile Hill, with the offending circuit identified rather than guessed. Tell us the vehicle and the symptom and you will get a firm price before anyone sets off.
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.
Repeat flat battery questions
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 Tile Hill and the CV4 area for this?
Yes. Tile Hill is inside our routine coverage from Oldbury via M6 J2/J3, roughly 4 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
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.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.
Drain faults found nearby
Recent job nearby: a car in Tile Hill 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 J2/J3 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
Where we test
Working out from CV4, the practical radius for a van jumpstart takes in Coventry, Nuneaton, Bedworth and Rugby — all within a few minutes of M6 J2/J3.
Why this is safe to book
- We will not sell a battery to a car whose battery is not the fault.
- Fixed prices agreed before dispatch — no callout fee just to open the bonnet in CV4.
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
On-site test
Voltage, load, alternator output at 2000 rpm, parasitic draw. Real numbers, not guesses.
- 4
How a drain is actually traced
Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.

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 Tile Hill and the real fault usually appears within the hour. If you would rather plan it than react to it, a van jumpstart can be booked for a time that suits.
