Non Corroding LA Batteries

[blkrnnr]

Hi,
My OEM panasonic (07 v6) served well for the past 13yrs/~95Kmiles.
It's time to replace.
I am looking at Costco's 27F regular LA (710CCA/165RC) vs 24F AGM(710CCA/120RC).
It will be used as starting battery on mostly highway duty.
I want a battery with higher RC and also want non-corroding terminals.
OEM I have never corroded. It is almost as clean as when I got it back in 2007.

Are current regular LA batteries still prone to corrosion?
What reasonably priced options out there (ie no Northstar/X2Power etc for 300+ dollars) that will not corrode and will have close specs to OEM battery?
Anyone running Costco's 24F AGM? Are you happy with it?

Thanks

You said Costco AGM- Where I am a few hours from you to the east all the batteries at Costco are Interstate brand. Do you actually have Costco branded batteries?
When I replaced the battery in our FJCruiser I bought an AGM at Sam's Club. It has done fine for several years- they are made by Deka and labeled Duracell in the east and Eveready in the west- same battery. No corrosion issues.

No, I think all Costco batteries are made by (Johnson Controls) and branded Interstate.
24F AGM is special order per their website.
So looks like if I want a AGM 27F battery with RC close to OEM, have to pay ~300 dollars.
