I have no problems with Interstate. Good warranty and network if its needed. But as I get money saved up, and batteries wear out, I'm replacing all mine with these.

They are not cheap by any means. But if you take basic care of them, they seem to last forever.
I got real tired of replacing battery boxes in my truck.
Despite acid neutralizing mats, and frequently cleaning, my driving style caused corrosion with regular batteries.
These batteries do not leak. At all. Plus they actually do what the Optimas used to do, and do it better than they ever did.
The only way to kill one of these things, short of a .30-06 bullet......Not me, a friend. Shot his own truck.
Got the deer though, swore it was worth it......
Anyway, never let one discharge all the way. If you run it down it may not recover if you let it sit under a load while dead for a long time.
Overcharging would do it too, but the same could be said of any battery.
Like I say, the price is not for the faint of heart, but you get what you pay for......
