I did a search and could not find a answer but i am sure its in here somewhere.

I was wondering what is a good way to know how much amps can you pull off your battery before you run the risk of ruining your alternator?

I have a 08 Jeep wrangler I don't know the amp's the alternator puts out. I tried searching for it online with no luck. a few third party replacements were around 100-120Amp alternators. Thanks
