How do I check if my Vauxhall Grandland's battery is working properly?

I've been having some issues with starting my car lately and I'm worried that it might be due to a faulty battery. How can I test my battery to make sure it's still in good condition and not causing any problems with my car's performance?

First, you can use a multimeter to measure the voltage of your battery. A healthy battery should have a voltage between 12.4 to 12.7 volts. If your battery's voltage is significantly lower, it might be time to replace it.

Another way to check your battery is to perform a load test. This involves using a battery load tester to apply a load to your battery and see if it can hold its charge. If your battery fails this test, it's a clear sign that it needs to be replaced.

You can also visually inspect your battery for any signs of corrosion or damage. Make sure to clean off any build-up of corrosion on the battery terminals and cables. This can greatly improve the performance of your battery.
