I've now had my INT 650 for 6 months. It holds a charge of 12.75 v and almost immediately goes "green" when I put it on my battery tender.I have a cheapo battery analyzer that seems to work on my cars, but shows only 50 cca for the INT. Any thoughts on this? What is the cca rating for the original battery? A nit-pick: getting to the battery is kind of a pain. Oh, well.
