Can you test a car battery and alternator with this?

Hi! Yes, this is an excellent multi-meter with which you can do that. A fully-charged auto battery will read between 12.5 and 12.8 VDC. You can check your vehicle's alternator by attaching the multi-meter's black and red leads to the black and red battery posts while the engine is at idle. With no accessories on (radio off, etc) you should read 13.7 to 13.9 VDC. IF the vehicle has an AGM type battery in it, then the voltage reading, no load, should be around 13.5 VDC. You can now check the alternator voltage output with a load on it. Turn on some accessories in the vehicle, like the A/C, the radio and the headlights - the alternator's voltage output shouldn't vary more than a 0.1 of a volt from the no-load reading. If the voltage reading drops significantly, then the voltage regulator inside the alternator has failed. These are simple tests that you can make in your driveway with your multi-meter. If you want more sophisticated testing of your battery or alternator, you'll have to take your vehicle to an auto repair shop.........I hope that this helps you a little.

Fully covers my needs and really well built for a very low price. But this is coming from a hobby user so can't say anything for professional use. Would personally say this is a perfect entry level multimeter primarely because it does exactly what it needs to do for a rather small investment. The instructions are sadly entirely in German though but it hardly matters since multimeters all use about the same symbols so a quick google search and you can find perfect English guides that applies to this product.

This has turned out to be an excellent tool for my audio restoration efforts. It seems to be quite accurate, easy to use, easy to read and offers nearly all the functions I could want or need. Great value for the money.

It uses cheap AA batteries. Other multimeters use more expensive 9V batteries.
