Hey all.

I have no idea about all this power stuff.

Been looking at power supplies and I know what I want to get but I want to ask about the Amps, specifically how many hours I can get out of a scope. This is only to power a scope, nothing else.

- 900 Amp, 12V, 17Ah (is what I am looking at)
- 500 Amp, 12V, 9Ah (is what I am considering since I found one for $45).

So how many hours can I get out of these two different powers in one night?

Also can someone clarify what the different between the Amp value and Ah value and what they contribute to so I know for future reference.

Thanks guys!
