That gets guaranteed from the technology it gets made from, to be exact, lithium-ion technology, which is a different form of battery-powered delivery.
A battery with a lithium-ion has a different core, so it performs a big hit of power upfront, is small and surprising light.
The installation on this is pretty easy since this thing gets made to factory stock battery dimensions, so it bolts right in.
With all of these pros, there are still some things you need to keep in mind if you are thinking of purchasing an Antigravity battery.

They are the cheapest batteries out there, but it comes with the negative sides.
First of all, they will not last as long as any other lithium battery, and you will need to check and fill levels frequently. Standard is a one-year warranty, but during this time, the battery will 100% get the job done.
