Antigravity lightweight batteries is famous for light, powerful batteries. In addition to batteries that can be installed in place of the heavy lead-acid units that come in popular ATVs and UTVs, Antigravity makes tiny little jump-start units that are slightly bigger than a cell phone but will jump start an ATV, UTV or even your truck! The Micro-Start line-up has been redesigned, and the new models will start your vehicle or charge 12-volt machines, 19-volt laptops or two USB devices. We love Micro-Starts and use them all the time. The new Micro-Starts will be available in April. Check out www.antigravitybatteries.com.
