    Got my battery in the mail, and I put it right in. Just so happens that my neighbor with the V-Barf, happened to be there( sorry don’t usually dog anyone’s choice of ride, but this guy is always talking about Harley’s reliability) anyway, I knew he was there to watch me fail. With my new Antigravity battery installed, I flicked the switch and my Sportster fired right up! Better and quicker than ever! Shut him right up! Everything went well, on the install, my only suggestion for future batteries is too move the terminals down on the face, for this application. Just took a few more minutes to get them to mount up top. Otherwise, I totally love your batteries! I would recommend these to anyone! And it weighs about 4 pounds less than the lead battery! It won’t leak!, and it’s way more cranking amps than that crappy factory battery! If you haven’t tried one you should! Best of all, 3 year warranty people! Nobody does that unless they back their product! Quick service and all questions answered promptly and with a great care.
