    Purchased one of these back in May of 2013. Didn't have any issues til early this year. Great battery, held up great after 2-3 years... Quite surprised due to the type of battery it is (AGM). I did have similar issue as stated above (Jeremy's review) that battery will drop voltage to 9v and stay there... Not having enough juice to crank over my SR20DET. Currently having the staff at FRsport helping me out to see if by any chance battery has any kind of warranty. So far everything is well informed and done on time.
