I have have good luck bringing sulfated Optimas to my local Interstate Battery. They’ve brought several back from the dead for me and they went on to last a very long time.
I got a red top optima, put the subaru battery blanket on it. Good down to -10f.
Optima Red Top has been treating me well.
I like AGM batteries. Using optimas now, whenever these finally die I'll try another brand. 4 years in now and I can't notice any loss of capacity yet. They work amazing when it is like 0 degrees F, too.
If you do need one, optima is pretty good but expensive.????
I have a VR6 swap that Sal at S&P did for me and we used an Optima Red Top.
I've had an Optima battery for several years. Still cranks my G20 van as if were brand new.????
Skip the dupmtima battery and save the coin. The extra capacity of a larger battery might not make the battery last longer (+5-7 years), heat kills batteries more than a few seconds of starting, and heat doesn't care if you have a small or large battery.
Optima has been garbage for about a decade now, ever since they were bought out and production moved out of the country. Quality immediately took a huge dive.
I'd be more concerned about the Optima battery - they have been crap quality for years now. Probably better than VW OEM junk though.
