This Battery Relocation Kit comes with everything you need to replace your incredibly heavy, OEM battery with a lightweight battery and relocate it to the trunk of your B6-B7 S4 or A4. This kit will fit ANY B6 or B7 A4 or S4. Depending on the battery currently in your car (OEM or replacement "brand-x" lead-acid battery with a lower CCA rating than stock), our Lightweight Battery Kit will net you a weight savings of anywhere from 17.5 pounds to 27 pounds. **NOTE: JHM has seen a wide range of batteries on the B6-B7 chassis cars that can weigh anywhere from 45 to 60 lbs. Additionally, relocating your battery to the rear of the car in the spare tire well gives you a better front to rear weight distribution allowing for better handling performance.

You can use the JHM Lightweight Battery Relocation Kit to install almost any battery in the trunk of your car. We selected the Optima Yellow Top battery because it provided the best compromise between weight loss and daily drivability. We have used this kit to run MUCH lighter batteries but if you're not driving on the highway for extended periods of time, these smaller batteries may not accommodate your daily driving needs.

We have the battery located in the spare tire well of the trunk. This puts the weight of the battery as low as possible in the car in order to achieve the most improvement in handling. However, our kit allows for some customization and gives you the ability to mount a lightweight battery almost anywhere in the trunk. Mounting the battery in the spare tire well does eliminate the ability to put a spare tire in your car. Since our JHM Lightweight Battery kit emulates the OEM battery setup of the RS4, we also decided to adopt Audi's OEM spare tire replacement strategy - but at a non-OEM price! We recommend purchasing a "Slime" based emergency tire repair kit
