Ive tested the battery several times and it outperforms its CCA rating and the battery terminals dont look too terrible but ive cleaned them anyway.
The pattern I see is that it cranks worse If I try to start it back up right away as opposed to letting it sit for an hour or so.

Also it cranks just fine with a battery charger attached.

Thanks

Sounds like our notoriously crappy cable ends not getting a good connection on the posts since you said you load tested the battery. Should be one of those two.
