Hi All, Antigravity Batteries http://antigravitybatteries.com has evolved to the next generation in our development of our ultra powerful lightweight Lithium Powersports Batteries. As always we are offering our 10% discount code "adventure" to all the inmates... just punch it in at check out. We are super excited to post about our new line of Direct OEM replacement batteries but with LITHIUM inside.. These batteries are Direct OEM replacement size for most all modern bikes yet offer substantially higher cranking amps than lead/acid or other Lithium batteries and have wieght savings of up to 80% over lead/acid...These new models come in the most popular OEM case sizes used in modern bikes... AND as always we also have our Ultra Compact Small Case models that are the most powerful, smallest and lightest format of any battery available.... So now you have the choice of either direct OEM sizes for a drop in fit or the ultra small format to save space in the battery tray... So what set Antigravity apart from the other Lithium Batteries on the market??? I'm glad you asked.... Lets compare Antigravity to one of the Lithium companies that markets A LOT more than we do and starts with an "S" 1) We are made in America... Los Angeles actually. 2) We offer a 3 year warranty as compared to a 2 year warranty and don't have warranty voiding issue like if you get salt on the terminal your warranty is void. Read the warranties....our competitor also voids the warranty if you allow the battery to drop below 12.6v( thats pretty wierd at some point a battery will go below that)... Our batteries do NOT have little issue like this that void the warranty because they are built better and stronger with large brass terminals to flow the power and handle abuse. 3) Our batteries offer much higher cranking amps which maintain much higher voltage on start up and a faster motor spin on start up which aids in starting.... For example in roughly the same size battery their puts out a Max of 270 Cranking Amps, yet the Antigravity can put out 360 Cranking Amps or you can get the higher power model that puts out 480 Cranking amps... yet is the same size as our competitor with close to twice the power. 4) We are waterproof... our competitor is NOT.... If you dump the bike in a water crossing you can see some serious damage with theirs... not with ours... water tight seal... Yep, that's pretty important in an off road bike. There is an Adventure Rider thread http://advrider.com/forums/showthread.php?t=770364 that some may be intersted in to learn more about Lithium batteries. One of your resident inmatesis doing some testing on Lithium batteries,actually beating the hell our of these batteries....Antigravity doesn't come into the picture until around page 7 or 8....but he beats our battery up too...and check the results we do great. Here are some pics of our stuff... Small Case models 4- cell and 8-Cell... also available in 12-Cell and 16-Cell models... New OEM SIZES YTZ7-S with Lithium found in all Euro and Japanese Enduros... 240 Cranking Amps! Twice that of Lead.YTZ10-S same as YTZ12 and YTZ14 found in most larger KTMs YTX12 and YT12-BS Case format found in many Euro and Japanes bikes used in BMWs from 360 to 720 cranking amps.
