How do I check my Vauxhall Astra's battery health?

My Vauxhall Astra has been having trouble starting lately. How can I check the health of my battery to see if that's the problem?

You can use a multimeter to check the voltage of your battery. The optimal voltage should be between 12.4-12.7 volts.

Another option is to take your car to a mechanic or auto parts store and have them do a battery load test. This will give you a more accurate reading of your battery's health.

If your battery is low, check for any corrosion on the terminals and clean them if necessary. Also, make sure your battery connections are tight.
