Anti-Gravity AG-AT12-BS-HD-RS Battery

This is my 2nd antigravity battery. These batteries are great, had absolutely no problems with the first one. Read the instructions maintain them who has instructed and you will have no problems, they are a little pricey but well worth it.

Costs more but got tired of having battery issues for my vstar , lots of power, everyone said great things about reliability

Being an avid rider for over 30 years, I have gone through some batteries. And most of the time, when they go dead-dead is when you get one of those really nice days coming out of winter and want to go for a short scoot. Now you find yourself going to the motorcycle shop to buy a new battery. And I have had maintainers galore connected, but those have their issues.Now, I did research on these lithium batteries, and the more I read, the more I became convinced to get one. This one, in particular, is a step above most, for it has a built-in cut-off switch. When the battery gets to a certain level, it will cut off all power to the bike. But all is not lost! As simple as getting your cover off (seat, fairing, etc., there's this little button that you press, and the battery will give you enough charge to get the motor started. How do I know this? My friend wanted to hear my bike, so he gave it a start and did the child things as a non-rider does, but when he went to shut it off, he hit the kill switch and didn't turn off the key. Well, the next morning, I went to start it, and no go! Calling him every name I could think of while taking my seat off, I hit the button, and it started right up, back on the road.I also have the Bluetooth adapter that I can check the voltage, cranking, and charging system. It also sends me notifications of the level of the battery. When I checked it at the above particular time, it was at about 15%; by the time I got home which was about an hour ride, it was at 100%. And as for a maintainer, I don't need one, if I can't get out on a ride to charge the battery, it will shut off, and I just need to press the restart button.You may look at the price and say too much for my budget, but I recommend investing the extra money and having peace of mind that you will never be stranded by a dead battery. And trust me; we have all left the key in the on position at some point.I will tell you to ensure your charging system is good; these batteries need that to recharge. I am so happy with this system that I bought a second battery and adapter for my other bike.The other nice thing about this battery is its weight, it only weighs 3 pounds!

use in my '13 diavel. leave negative off during storage in unit with no power. holds charge so i can start it every week no problem

Failed after only two months use, when I went to check the warranty I saw you had to of registered the battery after purchase to qualify for a replacement. After seeing this I opened the battery and found that of the 8 mosfets on the bms 5 of them had failed. I wanted to replace them but these mosfets are no name units and anti gravity provides no schematics for repair.After seeing the lack of quality inside this battery I don't even want a replacement unit I want a return because I won't risk putting this battery in anything I care about.
