safe to use on optima red top?

I don't see why not. Red tops charge the same way as any other battery you would use in your Jeep.

Not true,AGM batteries are very different from Lead Acid battteries.Look for a charger thats designed to charge them(I beleive the "Battery Tender" is one).
 
if an optima falls below 10v a standard charger will read it as a dead short inside and the charger's internal protection circuits will not allow it to charge. You're reading up on optima's webpage for the info, that's a good place to start. I get customers turning in "bad" red tops all the time as cores, i started saving them and trying to charge them on an AGM charger after reading that info, i've gotten 4 perfectly good red tops out of it.
