ARB onboard air: Is an upgraded battery needed?
I just installed my ARB compressor with the air hose option. My locker was also just installed last week. Everything works great but I have a question... I haven't used the compressor yet to air up tires, but I'm concerned!
When I activate the compressor, it really seems to draw alot of power. I turned it on the other night and it runs for a second to charge the small tank. When I did this the lights dimmed quite a bit!! Makes me wonder what would happen if I tried to air up 4 tires!!!
I know at some point I need to upgrade to a new battery like the Optima but will the stock battery get me by for a while? I just dont want to air down somewhere and then kill the jeep trying to air them back up!! ( I would keep the jeep running of course!)
Any advice?!

I had the same problem with all my accessories and dual viair compressors, I switched to a Die Marine battery after the OEM battery died and now the compressors are running full strength and no dimming.
In a year or 2 I'm going to upgrade the alternator to a Mean Green which raises the idleing amperage to 90 instead of 40

You'll be fine with the stock battery. I ran mine with the stock battery. The stock battery lasted 3 years. I then switched to a blue top.
If you are worried, just shut off the A/C, radio, and other electronics when using the compressor.
Upgrade when the stocker dies.

Higher idle?
The AEV Procal has an option to temporarily increase the engine's idle speed to a preset RPM. I don't have any electrical accessories to try it out on but I wonder if this would help?

This most likely is a stupid question but I will ask anyway!
So when using the compressor or winch, as long as I keep the jeep running during use the battery should be able to continue charging, and shouldn't leave me stranded somewhere, right?

I've had no problems airing up 4 Jeeps in-a-row on battery power, using a stock battery.
Having said that, my ARB compressor seems to pump faster when the JK is turned on vs. running off of battery.

+1 I filled up 7+ Jeeps before the compressor overheated. Battery did fine just keep the engine running.

Using the winch is different. It draws an IMMENSE amount of power.
A lot of guys with hand throttles made from a bicycle gear shifter will set it to 2500rpm or so.
If you use your winch on a pull, you will often hear it bog down when the going gets tough. If you press on the gas and give it more juice, it will often times speed back up and have an easier go at it.
That being said, when I'm winching a HARD pull, I usually do it from inside the jeep so I can give it some gas.
The pro-cal feature that does that is pretty cool.
