Antigravity Batteries YTX12 20-Cell 600CA Lithium Battery

This is the 20-cell version that comes in the OEM YTX12 Case format. It has a massive 600 Cranking Amps and is a direct replacement for the standard YTX12 Lead/Acid battery. It offers more than twice the cranking power over the lead/acid version of the battery while being about 5 pounds lighter! If you have any modifications or desire more power and more capacity you should leave the old technology behind and chose Antigravity.

Technical Specs:

  • 600 CA- Cranking Amps at 32°
  • 16 Ah- Amp Hours
  • Size: 5 7/8" long x 3 7/16" deep x 5 1/8" high
  • Weight: 5 lbs 


  • Available with a right-side or left-side positive terminal (shown)
  • Direct replacement that offers less weight and much more starting power
  • Ultra-lightweight and high-power Lithium Nano-Phosphate motor-sport battery
  • Can hold a charge up to a year provided there are no parasitic drains
  • Built with high quality standards with unbreakable brass terminal design
  • Excellent for every day use in bikes up to 2000cc
  • Factory activated
  • Made in the USA

Thomas V: I don't think so. I did not have to do anything to my ZX-14's charging system. Although the bike engine isn't stock, the charging system still is. Btw- the battery has NO problem turning over my high compression 1464 cc motor! Sep 18, 2014
