I was excited to try a high powered, light-weight lithium battery for my 2001 Ducati 996 and decided to go with Antigravity (https://antigravitybatteries.com/). 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 Motostrano 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.

The compact size and ability to install this battery is unlike any other. The power that this battery is like lightning in a box.

Installed the 16 cell small battery and so
far it has worked very well. The battery looks
and feels like a very high quality unit.
I like the fact that it is so small that my
1998 Honda VFR800 has lost 8 pounds.
The CCA of 410 is amazing!
Expensive but well worth it.

we have tried most of the top brand lightweight batteries out there and ANTI gravity is by far the best .
