Digital Multimeter question

Will this relatively cheap and basic digital multimeter be able to check for voltage and parasitic amp draw on a car battery?

Digital Multimeter DT 830D | eBay

I know I can use this multimeter on small things like AA, AAA, 9V, button batteries etc., but will this be safe to use on say a car battery? (of course with everything turned off).

I've never owned a multimeter before so this would be my first time.

A car battery is only 12 volts, no matter if the car is running or not. High voltage is in the coil & spark plugs. If you have a particular problem with the car, you might want to ask that question instead.

Yes you can use on car battery's. Car battery volts are 12 and charging volts usually around 14. Should not even hurt meter even if you happen to forget and leave meter set for ac volts. It will not give right readings but will not hurt it.

I used to have a cheapo multimeter that I fried on my 12v truck battery. Was testing a variety of things... voltage then resistance... forgot to switch it to the correct setting before going back to the battery and smoked the wires. Now I have a decent one that's protected from dumb mistakes like that.
