Antigravity Battery

[Evan]

In browsing through a motorcycle catalogue, I saw listings for "antigravity lithium small case format" batteries. Checked out their website at http://antigravitybatteries.com/ytx12-20/ for a Venture Royale. While very expensive, it does look like a very powerful (600 cranking amp) light weight and long life battery. Does anyone know about these batteries for our 1st gen bikes? Wonder how do these compare in performance to a Deka battery, which costs much less?

3 year warranty on a $360 battery?

Yes, but look at all the money you'll save on tires by using an anti-gravity battery.

The big downer to me is that it is not recommended for under 50*F.

That's 3/4 of the year......

That is just where the riding is starting to get good.

 

The other issue with lithium batteries, and they mention it repeatedly, is that if you ever run it down to under 10.5V it is junk, and they are very clear that this is NOT covered under warranty. Just one time leaving something turned on and $360 is gone.

I believe these are " Lithium " type batteries.

 

About 2 years ago I talked to a parts counter guy at a Yama dealer. He told me the first year or so they came out they were failing big time. -----------But -- they had been fixed, as he said.

 

The dirt bike racer guys really like them due to the ---- large weight reduction !! ---- But for our bikes, it seems to really be a waste of money.

Weight reduction for Small displacement raceing bikes is a Big Deal !!! Keep that in mind.

 

I believe the technology in these things is the same type of bats, that are catching fire, in airplanes, and electric cars. I'm sure you all have heard the news reports concerning the fires.

 

Last week saw the report of a Radar Detector, left on a car windshield, in the hot sun somplace, and the battery Exploded, completly destroying the car dash board !

 

Also, a few reports of Cell Phones, catching fire due to these batteries.

 

Anyway, I would stick with the AGM Type batteries. They don't EXPLODE !! ---

 

I am useing them in 3 bikes now, and my Ham Radio Installation in my 08 Chev Trailblazer.

AGM's cost More, then Lead Acid, but much less then the new Lithium Ion types.

 

Check out the DEKA brand AGM types, Also of note, Harley dealers are now selling AGM's under their own brand name.

I wouldn't buy a second one for nobody. It charged up fine and cranked her over like a powerhouse, but no matter how hard I jump on the seat I can't get the tires to hit the ground... kinda makes the centerstand redundant as well.

Got a buddy that runs them in all his bikes, he has a lot more spare $$ than I do...
