The only concern is the weight... removing them and replacing them is a fairly easy task... disconnect negative, then positive... remove the two bolts on each bracket holding the battery in place... and slide out...
I like to put electrical tape on the terminals while handling, to avoid any accidental contact with anything... same with the cables.
Easier said than done because of the weight... plus the dirt in place and lack of handles to pull makes it difficult to slide out... I have seen folks make rubber pulls that they bolt to the terminals (nothing that conducts electricity of course!!!)

When I bought mine, these guys had the best prices at 250.00 shipped... I see now that they are 299.99 and out of stock until 9/20.
