House Batteries 6volt deep cycle

We had 4 Costco Interstate 6 volt prior to installing a residential refrigerator, at that time we added 2 more (6 total replaced all at the same time) still CostCo Interstate. Over the last 20 years we have had 4 different units with various batteries and are very happy with the performance of these Interstate batteries. As a practical matter I do lean toward one of the prior postings, in that, all batteries are manufactured by 2 or 3 makers and as such in many ways there is little difference. Proper use age and care play a major role in both battery life and efficiency.
