Battery Keeps Going Flat in Attleborough? Drain Testing & Battery Replacement
Flat again in Attleborough? We measure quiescent current and alternator output before selling anyone another battery. Mobile Battery Replacement, 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.
Mobile battery replacement across Attleborough and the CV11 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.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Attleborough — a 10-minute trip never replaces the charge that starting consumed, so the battery slowly sinks regardless of health.
Locally that means the streets between Attleborough and Nuneaton, with access via M6 J3 and A5 and a practical radius reaching Nuneaton (~1 mi) and Bedworth (~4 mi).
Drain faults found nearby
Recent job nearby: a car in Attleborough 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
- 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.
- Correct chemistry every time: flooded / EFB / AGM matched to what the manufacturer specified
- On a battery replacement the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.

Repeat flat battery questions
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 Attleborough and the CV11 area for this?
Yes. Attleborough is inside our routine coverage from Oldbury via M6 J3, roughly 1 miles from Nuneaton. We cover it alongside Nuneaton and the surrounding streets.
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.
Q.What's the difference between AGM and EFB?
AGM is a fully sealed absorbed-glass-mat battery for premium and stop-start; EFB is an enhanced flooded battery for entry-level stop-start. Fitting the wrong one is a warranty-void job.
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.
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.
- Fixed prices agreed before dispatch — no callout fee just to open the bonnet in CV11.
Stop buying batteries. Find the drain.
Proper quiescent current testing in Attleborough, 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.

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 Attleborough and the real fault usually appears within the hour. If you would rather plan it than react to it, a battery replacement can be booked for a time that suits.
