Repeat Flat Batteries — Tile Hill fleet jumpstart & Diagnosis
Flat again in Tile Hill? We measure quiescent current and alternator output before selling anyone another battery. Mobile Fleet & Business Jumpstart, 24/7.
A healthy vehicle should draw around 20–50 milliamps once everything has gone to sleep. A faulty module, an aftermarket alarm or a stuck relay can pull ten times that, which flattens a good battery in two or three days.
Business account jumpstart and battery replacement across Tile Hill — priority response, single monthly invoice, no per-job admin, no chasing drivers for card payments.
automotive R&D, higher education, logistics operators in Tile Hill are our regulars — we build a vehicle list against your account so future calls are one text: reg + address.
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.
- Priority dispatch for account customers — fleet jobs jump the domestic queue
- On a fleet jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
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.
How the visit runs

Priority dispatch
Account jobs go ahead of retail callouts, typical arrival 30–45 minutes.
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).
Where we test
Working out from CV4, the practical radius for a fleet jumpstart takes in Coventry, Nuneaton, Bedworth and Rugby — all within a few minutes of M6 J2/J3.
Who this page is for
Owners in Tile Hill on their second or third battery for the same vehicle.
Domestically, post-war estates and modern infill dominate around here, which shapes how these jobs are accessed and worked.
Repeat flat battery questions
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.Can you supply and fit batteries at trade price?
Yes — Yuasa, Varta, Bosch and Exide at proper trade rates for account customers, fitted on your yard with OBD coding included.
Q.What if a driver is stranded outside our depot?
That's what account customers get priority for — one call from the driver, we handle it and bill your account, no card payment at the roadside.
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.
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.

Flat again?
Third battery in two years is a diagnosis problem. We measure the draw and the charging output before anything is replaced. Fleet & Business Jumpstart covers post-war estates and modern infill and trade vehicles alike, all from the same van.
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. Either way you get the readings, the reasoning and a working vehicle before we leave.
