How It Works

1

Battery Load Test

We don’t just guess. We use a digital tester to check the health, cold-cranking amps, and voltage of your battery.


2

Alternator Test

We run the engine with the headlights and heaters on to ensure the alternator is pumping out a healthy 14+ volts.


3

Parasitic Drain Check

If the parts are fine, we test the wiring to see if a faulty radio or module is draining the battery while you sleep.


4

Fit & Code

If you need a new battery, we fit a premium replacement and program it to the car’s computer so it charges correctly.

Warning Signs

Red Battery Light

If this illuminates while driving, your alternator has failed. You are running on battery power and will break down very soon.

Click, Click, Click

You turn the key and hear a rapid clicking noise, but the engine won't turn over. Classic flat battery.

Dimming Headlights

Your headlights get noticeably dimmer when you are idling, and brighten up when you rev the engine.

Whining Noise

A loud, high-pitched whine from the engine bay that rises with engine speed often means the alternator bearings are dying.

As well as a service I had asked for a tyre replacement & agreed the extra work to overcome misplacement of my locking wheel nut key. VRS later found my key (in a hidden compartment ) + advised the tyre replacement was unnecessary, saving me between £200 & £300 for which I am most grateful.

FAQs

Why do I need an expensive 'AGM' battery? +
If your car has a Start-Stop system, it requires a heavy-duty AGM or EFB battery. Putting a standard cheap battery in will cause it to fail within months.
My battery is new, why does it keep dying? +
If the battery is definitely good, you either have an alternator that isn't charging it, or a 'parasitic drain'—something electrical staying on when the car is locked.
Can you just replace the alternator belt? +
Yes! Sometimes the alternator is perfectly fine, but the rubber auxiliary belt driving it has snapped or stretched. We check this first.

Let us know what happens when you turn the key, and we'll tell you if it sounds like a battery, starter, or alternator.
