Wrong battery issues?

Has anyone tried using a battery that was'nt specd for your truck and had issues with things like the a/c,idle etc.?

Even a weak battery should not be a problem if the charging system is working properly.

Question:
Did you buy this trailblazer as a sbmerged vehicle?
Have you owned this vehicle since brand new?
Do you see any corrosion on any visible signs on electrical contacts?

Turns out it was the throttle body like someone suggested. I was thinking idle air control but it doesnt have one since its throttle by wire. Once i cleaned the throttle body no prblem.
