I just got back from Walmart. I measured the EverStart Maxx group 24 and group 24F across the base or bottom. Both measured 10” (254 mm). The BCI chart length values are different (260 mm for the 24 and 273 mm for the 24F) but they are the same across the bottom. They will both fit within the holding brackets. Noticed terminals were reversed between the 24 and 24F with the 24 having the correct configuration for my Kubota L3400DT. So guess I will go with the EverStart Maxx group 24. It will drop right in without having to mess with cables or rotating battery 180 degrees. Like the fact that the 24F has 750 cca while 24 only has 700 but don’t think the extra 50 cca is worth having to deal with the terminals being reversed. Spinning battery 180 degrees might be a problem because that would place the metal hold down bracket very close (maybe to close) to the battery terminals which would short out the battery if it touched both simultaneously.
