There is nothing else on the market like Antigravity Batteries! If you are looking to get more cranking amps, shave weight, run bigger winches, audio, or lights upgrading your battery is going to be the place to start. Instead of traditional lead-acid of sealed batteries Antigravity uses lithium, which means more power and less weight, plus since lithium batteries last longer than traditional batteries this may be the last battery you ever have to buy for your ATV or Sxs!
