XS Power batteries are absolutely incredible in quality, and performance! I have been using the same XS Power D2400 batteries in my show car since March 2007. That is 6+ years, under extreme loading and performance demands!!! In all of my 23 years in car audio competition, and many years before that building custom cars, no other battery has even come close to performing like the XS Power batteries.
