Battery Keeps Going Flat in Olton? Drain Testing & Battery Replacement
New battery still going flat in Olton? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus battery replacement on-site.
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.
A cheap battery from a chain retailer in Olton, fitted without OBD registration, will fail early on any car built after 2012. We fit tier-1 batteries and register them to your car properly.
The wrong battery in a stop-start car will show a warning light within days and drain itself trying to charge to spec. We fit the OEM chemistry every time.
Usage patterns that flatten good batteries
Cars left standing on Edwardian semis for a week or more between uses are the other common case in B92.
Locally that means the streets between Olton and Solihull, with access via M42 J4/J5 and A34 Stratford Road and a practical radius reaching Solihull (~2 mi) and Shirley (~2 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.
- Old battery taken away for proper lead-acid recycling — no charge, no landfill, DVSA-compliant paperwork
- Every battery replacement finishes with a charging-system reading, so the same fault does not reappear next week.
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 Solihull Metropolitan Borough Council.

Low-mileage drivers whose cars sit for days between short journeys.
Domestically, Edwardian semis and converted flats dominate around here, which shapes how these jobs are accessed and worked.
Drain faults found nearby
Recent job nearby: a car in Olton 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 M42 J4/J5 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
How the visit runs

Vehicle lookup
By reg on the phone — we confirm the exact OEM battery spec before quoting.
- 2
Fixed all-in price
Battery, fitting, coding, recycling, warranty — one number on the phone.

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.

Driveway fit
Memory saver in, old battery out, new one in and terminals torqued to spec.
Repeat flat battery questions
Q.Do you cover Olton and the B92 area for this?
Yes. Olton is inside our routine coverage from Oldbury via M42 J4/J5, roughly 2 miles from Solihull. We cover it alongside Solihull and the surrounding streets.
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.

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. Locally this is handled alongside Solihull and Shirley, so the van is rarely far away.
