Antigravity Batteries YT12BS 16-Cell 480CA Lithium Battery

This is the 16-cell high-power version that comes in the OEM YT12BS Case format. It has 480 Cranking Amps and is a direct replacement for the standard YT12BS Lead/Acid battery found in most Ducati motorcycles as well as many other models. This battery is about 5 lbs lighter than the stock Lead/Acid battery while providing twice the Cranking Amps for much better starting. If you have any modifications or desire more power and more capacity you should leave the old technology behind and choose Antigravity.

My experience with Antigravity wasn't so good
I was excited to try a high powered, light-weight lithium battery for my 2001 Ducati 996 and decided to go with Antigravity ( They’re made in the US and seemed to have a good warranty. I looked for reviews, but at the time there weren’t many available so I went ahead with my purchase. To summarize, in about 2 years I went through 4 Antigravity batteries and spent about $400.00. Here’s my personal experience for anyone that might be considering them.

12/05/11 - I paid $195 (179.99 + tax)
The original purchase of an Antigravity 8 Cell (YTZ7-8) from M*t*stran* Redwood City, CA.

01/03/12 - I paid $43 upgrade to an Antigravity 12 Cell (YTZ10S-12)
I realized that the 8 Cell battery wasn’t powerful enough to turn over my 996 effectively, so I paid for an upgrade. I understand that this was my fault because I didn’t read the spec’s carefully enough - according to Antigravity the 8 cell battery is “capable of everyday use in bikes up to 600cc”.

10/12/12 - I paid $75.00 for another upgrade, 12 Cell to 16 Cell.
9 months after the upgrade, I noticed that the upgraded 12 Cell battery started to perform poorly and I was having difficulty starting my 996. Shortly thereafter, the 12 Cell battery completely died and wouldn’t hold a charge at all so I returned it to Antigravity for testing. The technician claimed finding no obvious damage and didn’t provide an explanation why it wouldn’t hold a charge. I thought that perhaps even the 12 cell didn’t have enough power to start my bike repeatedly over a long period of time so I paid Antigravity the purchase price difference to upgrade from the 12 to 16 Cell (the YTX12-16, retails for approx $289.00 + Tax)

04/01/14 - I paid an additional $91.00 for a warranty replacement on the 16 Cell.
The 16 cell battery died and wouldn’t hold a charge so I returned it to Antigravity for testing. Again, the results were that there was no verifiable damage and no reason why it didn’t hold a charge. Antigravity didn’t offer to replace the battery at no charge so I paid the fee for a warrantee replacement. In my case I was given a 75% discount as per the 3 year warranty plan (6-12 Months — 75% discount from retail MSRP)

I should note that I ride my bike about 3 times a week for an hour or two under normal road conditions. I live in reasonable weather here in Northern California and I don’t race it. The charging system was tested to be normal around October 2012 by Nichols Sportbikes in Milpitas (who are awesome btw :). Also, I didn’t opt for the $120.00 charger that Antigravity sells and am of the opinion that a battery should last more than a year if you operate it normally - especially at those prices!

Personally, I’m going back to a regular battery after my experiences with Antigravity and Lithium batteries.

Major disappointment
Replaced after 1 year! 17,000 miles. Checked all the charging voltages, in spec before and after installation (January '15. Started with strong cranking of the FJR but faded until two or three attempts were needed (November '15) with the gauges dropping out due to low voltage during cranking. No answer from the manufacturer. Voltage and charging stayed at the same level but the power was not there.
Decided to go with another brand for a retry of a lithium power pack.

5 Rides and now it wont charge
Whats up with this? The most expensive/made in USA brand and I have something that is a DUD. I literally was watching the volts drop from 12 to 8 without starting.

One day it starts just fine and the next day (the next day) it wont turn over the engine.

Smaller size and weight
The smaller size (height) allows space for the extra farkles wiring under the FJR covers, big plus. The weight change is significant, I wasn't sure the battery was in the package when it was delivered, it was so light. The main reason for going for the Antigravity lithium is the cold cranking amps. After cold soaking outside at work at 32F, I had to push the FJR to get it to fire, it's a beast, now no more, soaking at 26F for most of the day, no problem starting.
The unexpected positive feature is the terminal clamps. They are integral with the battery and you are provided with square spacers for the leads, put the bolt through, done. Much easier than messing with a captured nut in a cage that falls out. Made installation easier.
Early days but the life expectancy should pay off. I read the review that was not overwhelming but good information so we'll see how we go. I will have to update as time and miles pass.
Delivery was first class, probably a day early, actually arrived on my birthday, the second day from the Sunday evening order. Well done Revzilla well packaged.

Don't waste money on a lead-acid battery ever again.
Installed the 16 cell battery on my Ducati Diavel. Cranks hard, and as I only ride the bike once per week, it's nice to know it can sit without a battery tender always attached to it. Plus you'll be amazed when you feel how light it really is... I thought the box was empty when I picked it up off my porch.
