Slickest of all, the Re-Start should never go dead, and you should never, ever need a jump.
It's warranted for five years, with the first three full replacement and the last two prorated. It all helps to extend battery life, and Antigravity says the Re-Start should last seven to nine years, depending on climate. BMS prevents overcharging and overdischarging, and its thermal management system balances cell use to optimize operating temperature. The tricks, after the lithium chemistry, start with a chip-controlled Battery Management System. They're available in many automotive group sizes, with multiple choices in cranking amps and reserve power. The Antigravity Re-Starts aren't cheap, but they're exceptionally light (all under 20 pounds) and loaded with high-tech features. Antigravity was a pioneer in lithium technology for portable jump starters and energy storage, and it has expanded into powersports and automotive batteries with its Re-Start series.
