The expensive Midtronics factor in temp. The cheaper ones don't. And there may be more than just that but it's one thing I am aware of.Reviving an old tread.
I have the Solar one, it was very inexpensive, looking for something a little better quality, particularly sine it’s reporting a brand ne east penn Duracell (fully charged) as bad and only 330 CCA (590 rated)
Midtronnics? Seems that the dealership go to.
Will the 100 do or do I need to get a 200/300?
