Thursday Tip: Doing A Battery and Alternator Test with an Electronic Battery and Alternator Tester

Car Battery inspection and test at Oliver's Car Services in Gorey

In the last post we looked at how to test your battery with a multimeter. In this post we look at how to check your battery with an electronic battery and altenator tester and what the results show you.

How many volts should a car battery have?

A good healthy car battery should register about 12.6 volts. Due to the way batteries discharge it’s important that you test the battery after it’s been sitting for at least an hour to get what’s called the ‘resting voltage’. Leave the car overnight and test before you start the car in the morning to get a really accurate gauge of the health of your battery.

If you’ve recently been for a drive, as long as the charging system is working correctly, the battery is likely to give a higher reading than the resting voltage, and so could be misleading.

How Frequent Are Bad Battery Results?

Recent research from aftermarket parts suppliers, Euro Car Parts suggests that 1 in 3 batteries tested will have some kind of issue or fault. Problems that faulty batteries can lead to include loss of power, inability to start the car, loss of lights, loss of braking, in fact the list is almost endless as a quarter of all breakdowns are caused by a faulty battery.

Pro Tip: Before you disconnect your battery make sure you know the anti-theft code for your stereo – You may find it won’t work when you reconnect it otherwise!
