Repeat Flat Batteries — Bilton fleet jumpstart & Diagnosis
Flat again in Bilton? 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 Bilton — priority response, single monthly invoice, no per-job admin, no chasing drivers for card payments.
We invoice monthly with full PDF breakdown per vehicle — clean for accounts to file, VAT-compliant, no per-job card fiddling.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Bilton — 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 Bilton and Rugby, with access via M6 J1 and M45 and a practical radius reaching Rugby (~2 mi) and Bilton (~2 mi).
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.
- Bulk battery pricing — replacement AGM/EFB batteries at trade rates, not retail
- Every fleet jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.
Who this page is for
Owners in Bilton on their second or third battery for the same vehicle.
Domestically, Edwardian villas and modern estates dominate around here, which shapes how these jobs are accessed and worked.
Drain faults found nearby
Recent job nearby: a car in Bilton 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 J1 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.

Repeat flat battery questions
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.How do we open a business account?
One phone call and a fleet list. First job on account can go the same day; formal terms confirmed by email overnight.
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 Bilton and the CV22 area for this?
Yes. Bilton is inside our routine coverage from Oldbury via M6 J1, roughly 2 miles from Rugby. We cover it alongside Rugby and the surrounding streets.
Where we test
Working out from CV22, the practical radius for a fleet jumpstart takes in Rugby, Bilton, Hillmorton and Newbold-on-Avon — all within a few minutes of M6 J1.
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 fleet jumpstart and quote your postcode — CV22 is a routine run for us.
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 CV22.
