Repeat Flat Batteries — Tile Hill emergency jumpstart & Diagnosis
New battery still going flat in Tile Hill? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus emergency jumpstart on-site.
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.
Stuck at the roadside in Tile Hill at 2am with a dead battery? We run a genuine 24/7 mobile jumpstart service — same price, day or night, no unsociable-hours surcharge.
We're based in Oldbury, minutes from the M5 and M6, so night response into Tile Hill is genuinely quick — no waiting until morning like some breakdown clubs.
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.
- Roadside safety kit on board — high-viz, warning triangles, torches, portable jump pack
- Every emergency jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.
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.
Flat again?
Third battery in two years is a diagnosis problem. We measure the draw and the charging output before anything is replaced. Same fixed pricing whether it is a emergency jumpstart at 9am or 3am, anywhere in Coventry City Council.

Follow-up
We check-in later to confirm the car is still starting and the battery is holding voltage.
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
Tile Hill sits about 4 miles from Coventry, and the same van covers Coventry (~4 mi), Nuneaton (~9 mi) and Bedworth (~5 mi) on the same run.
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, post-war estates and modern infill dominate around here, which shapes how these jobs are accessed and worked.
Repeat flat battery questions
Q.Will you come out in bad weather?
Yes — snow, ice, heavy rain, we still go. Batteries fail more often in bad weather, not less.
Q.Do you really answer at 3am?
Yes — a real person answers, not an out-of-hours message service. If we're on a job we call back within minutes.
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 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.
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.

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. That is the whole job: diagnose it properly, fix it once, and explain what caused it.
