Antigravity Batteries YTX12 12-Cell 360CA Lithium Battery

This is the 12-cell version that comes in the OEM YTX12 Case format. It has 360 Cranking Amps and is a direct replacement for the standard YTX12 Lead/Acid battery. This battery is about 70% lighter than the stock Lead/Acid YTX12 while providing about 100 more 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 chose Antigravity.

  • 12 Ah- Amp Hours
  • Size: 5 7/8" long x 3 7/16" deep x 5 1/8" high

  • Available with a right-side or left-side positive terminal (shown)
  • Direct replacement that offers 70% less weight and much more starting power
  • Ultra-lightweight and high-power Lithium Nano-Phosphate motor-sport battery
