Please note that we only sell the upgraded AG-24R-30-RS full size battery.

After over a year of testing, we are proud to introduce one of the single most effective weight saving modifications you can buy. This race battery kit weighs just 14lbs while delivering over 1200 cranking amps of starting power! That’s a weight savings of over 27lbs 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.

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.
