Battery Keeps Going Flat in Nuneaton? Drain Testing & Van Jumpstart
Flat again in Nuneaton? We measure quiescent current and alternator output before selling anyone another battery. Mobile Van Jumpstart, 24/7.
Buying a second battery for the same car in a year is the clearest sign the first one was never the problem. Something is either draining charge while the car sleeps, or failing to put it back while the car runs.
A dead Transit, Sprinter, Vivaro or Crafter on a CV10 driveway usually isn't a garage job. A proper mobile jumpstart with a 2000A+ pack gets you running in minutes without a recovery truck.
Around Nuneaton the common jobs are morning no-starts on the yard, lunch-break dead batteries at customer sites, and end-of-day flatlines after tail-lift or refrigeration use.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Nuneaton — a 10-minute trip never replaces the charge that starting consumed, so the battery slowly sinks regardless of health.
Locally that means Nuneaton itself plus the neighbourhoods that feed into it, with access via M6 J3 and A5 and a practical radius reaching Bedworth (~4 mi) and Bulkington (~4 mi).
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, Victorian terraces and post-war estates dominate around here, which shapes how these jobs are accessed and worked.

How a drain is actually traced
- Alternator output is checked under electrical load with headlights, blower and heated screen on, not just at idle.
- Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.
- Battery voltage and cold-cranking amps measured with a proper Midtronics-style tester, not a cheap voltmeter
- Van 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 Nuneaton and the CV10 area for this?
Yes. Nuneaton is inside our routine coverage from Oldbury via M6 J3, roughly 9 miles from Coventry. We also cover the surrounding neighbourhoods on the same run.
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.Can you jumpstart a large diesel van?
Yes — our packs are rated for LCVs and small trucks up to around 7.5 tonnes. A booster designed for petrol cars won't do it; ours will.
Drain faults found nearby
Recent job nearby: a car in Nuneaton 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 J3 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
Where we test
Nuneaton sits about 9 miles from Coventry, and the same van covers Bedworth (~4 mi), Bulkington (~4 mi) and Attleborough (~1 mi) on the same run.

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. If you would rather plan it than react to it, a van jumpstart can be booked for a time that suits.
