Are the Blues much different from the Yellow Tops?
I've been running Yellows in my Jeep due to the heavy electrical load from the winch--I've nearly drained the battery a few times having to winch myself out with the motor off--without issue.
From a quick glance, they seem to be the same construction?
It's been a long while since I looked at the differences. I know the red top are typical car use for starting with high surge loads. these are not recommended for deep drain usage.
There are 2 blue tops, and just realized the one I linked previosly is not the same version (dark gray) as the one I have being the light gray.
Essentially, the differences are in use cases. Lots of short but heavy loads vs long sustained loads. Looks like the blue tops are still Optima's best "drain to 0 frequently" type of battery where the yellows look like an occassional drain to 0 is survivable but not the recommended use case. I had forgotten the differences after making the decision years ago. Just looked them up again for a quick refresher
