Battery Keeps Going Flat in Nuneaton? Drain Testing & 24/7 Emergency Jumpstart
Flat again in Nuneaton? We measure quiescent current and alternator output before selling anyone another battery. Mobile 24/7 Emergency 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.
Late shift, night out, early flight — batteries pick the worst moments to die. If you're stranded anywhere from CV10 to the M6 J3 we're on it round the clock.
We're based in Oldbury, minutes from the M5 and M6, so night response into Nuneaton is genuinely quick — no waiting until morning like some breakdown clubs.
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.
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).
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.
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.
- Genuine 24/7 — nights, weekends, Christmas Day, New Year — same price as daytime
- On a emergency jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.

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.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.Is there a night surcharge?
No. Same price at 3am as at 3pm. We think surcharging people who are already stranded is bad business.
Stop buying batteries. Find the drain.
Proper quiescent current testing in Nuneaton, with the offending circuit identified rather than guessed. Tell us the vehicle and the symptom and you will get a firm price before anyone sets off.
Why this is safe to book
- We will not sell a battery to a car whose battery is not the fault.
- Old batteries removed and recycled on every emergency jumpstart.

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 Nuneaton 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.
