Why Your Battery Keeps Dying — Battery Replacement, Nuneaton
New battery still going flat in Nuneaton? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus battery replacement on-site.
Repeat flat batteries are a diagnostic job, not a parts job. The measurement takes longer than the fix usually does.
If your battery in Nuneaton is more than 4 years old and keeps going flat, you're past jumpstart territory — you need a proper replacement, fitted and coded on your driveway.
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.

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).
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.
- Fixed quoted price including battery, fitting, coding, recycling and warranty registration
- Every battery replacement finishes with a charging-system reading, so the same fault does not reappear next week.

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.
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 battery replacement and quote your postcode — CV10 is a routine run for us.
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.
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.
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
Working out from CV10, the practical radius for a battery replacement takes in Bedworth, Bulkington, Attleborough and Chapel End — all within a few minutes of M6 J3.
Repeat flat battery questions
Q.How do I know my battery needs replacing rather than jumpstarting?
If it's over 4 years old and going flat repeatedly, or the CCA on a load tester reads under 60% of rated, it's replacement time. Jumpstarting will only get you a day or two.
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 I lose my radio code and seat memory?
No — we use a 12V memory saver on the OBD port during the swap, so all adaptations and settings are preserved.

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.
