Hello Glenn,

I am also skeptical. Couldn't find out what the CT-400 is or who wrote
it or why, but the idea that someone would make a high-capacity Group 31
battery and then recommend it only for frequent charging use sounds
almost counter-intuitive.

After a very quick check of Exide's battery application guide, it
appears that their only Group 31, 925 cca battery carries a 24-month
warranty! Talk about disposable.

They have other Group 31's with lower cca ratings carrying the same
warranty, and they also have Group 31's with lower cca ratings carrying
six and seven year warranties.

But it is probably a true statement that all of the Exide Group 31's
rated at 925 cca will not last long, for whatever reason.

A similar statement could not be made about ALL of the Exide Group 31's
with lower 925 cca ratings.

Make sense? Sounds like it might be coincidence.

Here is the service bulletin they got from their chassis supplier:
