Giving 2 stars because the guy that installed the batteries each time was professional and very courteous. The issue is I've purchased two batteries within the last two years and the first one was dead at the 17 month mark, and more recently the battery only lasted 8 months. I was given every excuse why I couldn't get a refund, so I tried using them again, and like I stated earlier, the battery is dead at 8 months. I'll try again for a replacement battery, but if I get the run around again I'll never use them again. I don't believe these are new batteries as advertised.
