Is anyone able to speak to the quality and longevity differences, if any, between Group 49 and Group 93 batteries? Both are a perfect fit and suitable for my cars, but Group 49 is OEM.

The reason I ask is that, next time I get a battery, I'm going to go with an Interstate "blem." But apparently the Group 93s are much more likely to be in stock.

Thanks.
