Battery Keeps Going Flat in Moxley? Drain Testing & Battery Replacement
Flat again in Moxley? 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.
Battery gone in Moxley? Rather than driving to a fitting bay and queuing, we come to the vehicle — driveway, workplace car park, or roadside on the M6 J9 corridor.
Stock on the van covers every popular fitment: standard flooded 063/096/075/100, EFB start-stop, and AGM 019/017 for premium and stop-start applications.
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.
- OBD battery registration for BMW, Audi, VW, Mercedes, Ford, Vauxhall, Peugeot, Citroen — included in the fit price
- Battery Replacement work here is judged against the vehicle's own specification rather than a generic pass mark.
Drain faults found nearby
Recent job nearby: a car in Moxley 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 J9 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.

Usage patterns that flatten good batteries
Cars left standing on terraced streets for a week or more between uses are the other common case in WS10.
Locally that means the streets between Moxley and Wednesbury, with access via M6 J9 and A461 and a practical radius reaching Wednesbury (~1 mi) and Darlaston (~2 mi).
Where we test
Working out from WS10, the practical radius for a battery replacement takes in Wednesbury, Darlaston, Tipton and Great Bridge — all within a few minutes of M6 J9.
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, terraced streets and modern estates dominate around here, which shapes how these jobs are accessed and worked.
Flat again?
Third battery in two years is a diagnosis problem. We measure the draw and the charging output before anything is replaced. Same fixed pricing whether it is a battery replacement at 9am or 3am, anywhere in Sandwell Metropolitan Borough Council.

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 Moxley and the WS10 area for this?
Yes. Moxley is inside our routine coverage from Oldbury via M6 J9, roughly 1 miles from Wednesbury. We cover it alongside Wednesbury and the surrounding streets.
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.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
A battery that keeps dying is telling you about the car, not about itself. Measure the sleep draw and the charging voltage in Moxley 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.
