A car that will not turn over is a symptom, not a diagnosis. We test the battery, the alternator and the drain before anybody spends money, which is why we sell fewer batteries than we are asked for.

A battery can read 12.6 volts and still fail the moment it is asked for any current at all.
We load test rather than just measure, which is the difference between knowing a battery is charged and knowing it is healthy. Plenty of the batteries we are called out to pass that test and get put back in.
If the battery is fine, the next question is why it went flat. Usually that is the alternator not charging properly, or a parasitic drain from something that is not switching off - a boot light, an aftermarket alarm, a dashcam wired badly.
Short journeys are the third cause and the one nobody likes hearing. A car doing ten minutes twice a day never fully recharges, and no new battery will fix that on its own.
The test that actually tells you anything.
AlwaysMeasured running, under load.
CheckedFor repeat offenders.
Where neededRegistered to the car where the maker requires it.
IncludedTaken away and recycled properly.
IncludedIf it is fine, we say so and charge for the test only.
No upsellSlow crank, no crank, or flat every few days.
Under real current, not just a voltage reading.
Alternator output measured with the engine running.
If it keeps going flat, we find what is drawing.
And the old one taken away for recycling.
Registration and postcode. We will tell you what the car is, which service it is due on its own mileage, what that costs and when a van can get to you.

Prices are what the job starts at for a car this size; anything the van finds is quoted before it is done. Vehicle and mileage information comes from the DVSA record. Contains public sector information licensed under the Open Government Licence v3.0.
Yes, wherever it is. Most no-starts are resolved on the spot, and if it needs recovery you get told straight away rather than after an hour.
On many modern cars, yes. Fitting a new battery without registering it means the charging system keeps treating it as the old one. We do it as standard where the maker requires it.
Three usual answers: the alternator is not charging, something is drawing current with the car asleep, or the journeys are too short to replace what starting uses. We test for all three.
It goes back in the van and to a licensed recycler. It never gets left with you.
A flat battery is the one job that rarely waits, and it is short enough to slot into gaps in the day's run.
