The Antigravity Batteries AG1201 is an extremely versitile high power and lightweight Lithium Motorcycle/Motorsports battery. I has the capability for large weight reduction in the most compact size in lithium batteries in its class. It has 360 Cranking Amps yet is only 4.50" Length x 3.25" Depth and 4.25" hieght (to the top of the terminals). This battery is a great choice for those seeking very high power in a compact battery. It can replace the typical 12 Ah Lead/Acid battery with a weight saving of up to 7 pounds while offering much more cranking power. This battery is best used for applications where extreme weight loss and ultra compact size are desired.

best battery ever, power to weight ratio helps too! cutting 10 pounds off a bike always helps.

What can I say? It must be a small atomic plant in it. Starts my Sportster 1200 with no problem

Battery was great till it just stopped. Warranty not honored because it was used in a jet ski. The box has a picture of a jet ski on it and they make recommendations for jet ski applications...

To early to give you a complete review but I am very excited about the weight and size. I am in the middle of a little customization. I am very glad it is made in the USA....thanks

Since day 1 my 2009 Aprilia SXV cranked slow and had a hard start problem...especially in the cold. I installed a 12 cell AnitBravity battery and the problem is solved. Cranks faster and starts reliably.
Now I dont fear getting stranded.

I am building a L/S bike (long/skinny) using parts I've had for years. The front end is a Harman 15" over girder that I used on a 39 knuck in 1974. Using that front end as a starting point an building a copy of that bike but thus time I am using an Evo engine. Order a teardrop oil tank that was supposed to allow the use of a stock SoftTail battery. No way but the tank maker sold Antigravity batteries. I ordered direct from Antigravity, not wanting to deal with oil tank maker. Got the battery it fit and starts the 8o" Evo easily. Very happy with product. If you can afford one buy it thanks, The Grandimagineer P S. I am a 70 year biker and Mustang Person. That has been building bikes and Mustangs for many a year
