Why Your Battery Keeps Dying — Battery Replacement, Bedworth
Flat again in Bedworth? We measure quiescent current and alternator output before selling anyone another battery. Mobile Battery Replacement, 24/7.
Repeat flat batteries are a diagnostic job, not a parts job. The measurement takes longer than the fix usually does.
Mobile battery replacement across Bedworth and the CV12 area, with the correct AGM, EFB or standard flooded chemistry fitted the first time — not whatever's on the shelf.
A properly registered AGM battery in a BMW, Audi or VW will last 6–8 years. A flooded battery dropped in without coding, in the same car, will fail in under 2.
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.
- Tier-1 batteries only — Yuasa, Varta, Bosch, Exide — with a real 2–4 year warranty and traceable batch codes
- On a battery replacement the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
Drain faults found nearby
Recent job nearby: a car in Bedworth 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.

Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Bedworth — a 10-minute trip never replaces the charge that starting consumed, so the battery slowly sinks regardless of health.
Locally that means Bedworth itself plus the neighbourhoods that feed into it, with access via M6 J3 and A444 and a practical radius reaching Nuneaton (~4 mi) and Exhall (~1 mi).
Stop buying batteries. Find the drain.
Proper quiescent current testing in Bedworth, 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.
Where we test
Working out from CV12, the practical radius for a battery replacement takes in Nuneaton, Exhall and Bulkington — all within a few minutes of M6 J3.
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, ex-mining terraces and 1960s estates dominate around here, which shapes how these jobs are accessed and worked.

Repeat flat battery questions
Q.What do you do with my old battery?
It goes back to a licensed recycler. Around 99% of a lead-acid battery is recyclable. No landfill, and we don't charge for disposal.
Q.Do I really need OBD coding when the new battery goes in?
On post-2012 BMW, Audi, VW, Ford, Vauxhall, Peugeot and Citroen — yes. Without coding, the alternator will overcharge the new battery and kill it in under a year.
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 Bedworth and the CV12 area for this?
Yes. Bedworth is inside our routine coverage from Oldbury via M6 J3, roughly 5 miles from Coventry. We also cover the surrounding neighbourhoods on the same run.
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.
- Old batteries removed and recycled on every battery replacement.

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 battery replacement can be booked for a time that suits.
