Awefull quality batteries - does not even last 6 months

Bought a battery in March. The battery is faulty, we took it to Dixon to test. When I wanted to take it back (as they say they have a 24month guarantee), I was told in no uncertain terms that they will not exchange the battery. In the "gentleman's" own words " what are you going to do about it? sue me? He assured me there are so many people that come there and threaten him with lawyers, and he does not care. Horrible people. Terrible service. ********** quality. DO NOT WASTE YOUR MONEY HERE. YOU WILL BE SORRY
