Please note that although we feel that the AG-ATX30-RS battery works well for this application, we now offer an upgraded AG-24R-30-RS full size battery as an option (the full size battery does not have a Restart feature).
After over a year of testing, we are proud to introduce one of the single most effective weight saving modifications you can buy. Our new race battery kit, consisting of the Antigravity ATX-30RS battery, our custom powder coated battery mount & hardware, and protective gold heat shielding weighs just 6.4lbs while delivering over 800 cranking amps of starting power! That’s a weight savings of over 35lbs over a stock Lexus ISF battery, and best of all, the weight savings is up front where it affects handling and weight distribution the most. Weight savings is the key to extracting the most performance from your Lexus, especially when it comes to cornering, acceleration, and braking.
Up until recently, the only option to save weight was to use a lightweight 10lb AGM lead-acid race battery. Problem is, they have very poor cycle life and most of these batteries last about six months under normal operating conditions. One of the most notable features of the Anti-Gravity battery is the "Restart" feature. Anytime the battery loses charge below a certain voltage level, it simply turns itself off instead of depleting. This means that you are NEVER stranded in need of a jump start. You simply open the hood, hit the "restart" button and drive away!
Please note: This battery is intended for vehicles used primarily for high performance and race applications. This battery is not appropriate for cars with additional parasitic draw from accessories such as, but not limited to, high power stereo systems and air bag/lift pumps. We recommend using a lithium specific charger for maintaining batteries for cars that are stored for more than a few days at a time. Lithium-ion batteries require lithium-specific chargers. We recommend the CTEK charger we sell as an option with this product. Please refer to installation instructions for proper maintenance and charging of this battery.
