Repeat Flat Batteries — Coundon fleet jumpstart & Diagnosis
New battery still going flat in Coundon? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus fleet 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.
Fleets working out of the CV6 area — courier, plumbing, electrical, HVAC, roofing, letting agents — call us daily. We know your vans, we know your yard, we know when your first drop is.
Account customers get priority slots ahead of retail callouts, so a fleet job on your yard in Coundon won't sit behind three domestic driveway jobs.
Usage patterns that flatten good batteries
Cars left standing on 1930s semis for a week or more between uses are the other common case in CV6.
Locally that means the streets between Coundon and Coventry, with access via M6 J2/J3 and M69 and a practical radius reaching Coventry (~2 mi) and Nuneaton (~9 mi).
Who this page is for
Owners in Coundon on their second or third battery for the same vehicle.
Domestically, 1930s semis and modern estates dominate around here, which shapes how these jobs are accessed and worked.

Stop buying batteries. Find the drain.
Proper quiescent current testing in Coundon, with the offending circuit identified rather than guessed. We route in via M6 J2/J3, roughly 2 miles out from Coventry.
How a drain is actually traced
- Charge acceptance is tested, because a sulphated battery can read 12.6V and still hold almost no usable energy.
- Alternator output is checked under electrical load with headlights, blower and heated screen on, not just at idle.
- Vehicle register held on file — one call gives us the reg, spec, battery history and yard location
- Fleet & Business Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.
Repeat flat battery questions
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 Coundon and the CV6 area for this?
Yes. Coundon is inside our routine coverage from Oldbury via M6 J2/J3, roughly 2 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
Q.Do you do preventative fleet audits?
Yes — quarterly on-site checks: voltage, load test, alternator output, terminal condition on every vehicle. Reports emailed to your fleet manager.
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.
Drain faults found nearby
Recent job nearby: a car in Coundon 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 CV6, the practical radius for a fleet jumpstart takes in Coventry, Nuneaton, Bedworth and Rugby — all within a few minutes of M6 J2/J3.

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.
