Can't say enough about reconditioned batteries from Interstate. Bought one for $50 in 2015 for the 91. Lasted 6.5 years. Still worked, car started without difficulty, but only putting out 550 CCA. So replaced it with another one for the same price....so much for inflation!

Learned that they sell reconditioned AGMs for $70....so when the time comes for the CDI that's what I'll do.
