Have 2 red tops. One is dead, other is holding on.

One that works is in a 92 GMC safari. Had it since 2005. Had one in my 69 Charger. Bought that one in 2003. It lasted all of 4 years, it was on a battery disconnect, always tendered. Once you somehow drain a red top, there is no bringing it back to life. I tried the brake light over both poles to "excite" the battery...its now a door stop in the garage. I bought an AC Delco. 700CCA (versus the 960CCA of the optima) I dont have a problem with it. It kicks over my 440 every time with that mini-starter.
