The worst battery I have ever had is an optima red top. Purchased 8/25/20 and I just replaced it for the third time. Most batteries give me 7-8 years in daily drivers, thought the optima would be better, parts store said they are not what they used to be, lots of issues. Interstate batteries were always junk for me also.
Something with your situation is strange, or your supplier has old product. That is not a normal problem.
