    Same here. Battery is always on a charger.

    Glad to hear it. How many times have you had to use the restart button?

    If you have a full interior getting to the restart button behind the trim is a pain. But sounds like others who have the higher capacity lithiums like them.

    The battery I have is basically the size of a motorcycle battery.

    If its a track car or dont have much electronic options then the CSL/Mini battery is a good ligherweight option (H5 i believe)

    Beyond that is the lithium options which are big money and a pain in the butt for a weekend street car, but worth it for a track car.

    I own an antigravity battery and I don't mind it for a track car I know I would hate it on a street car.

    Thanks guys, I appreciate it. Too bad those antigravity batteries are on backorder.

    It came with the car so wasn't my choice. Model is ATX-20 so 20aH.

    Hi-Power lightweight ATX20-RS lithium motorcycle/powersports battery with RE-START Technology (built-in jump-starting). Replace YTX-20, more. 680 CA.


    It has the restart button in the trunk. Which is annoying if you get in the car and it turned itself off. Get one with a remote button if you can.

    Great for motorsport (4lbs!) but if the car sits for longer than a day or two it will shut itself off.

    I installed an Antigravity lithium battery in the race car and so far, so good.

    Antigravity H6/Group-48 Hi-Power lightweight Lithium Automotive Battery with RESTART Technology. Replace lead/acid battery in Hi-Performance Cars.

    OPTIMA 35 REDTOP Battery for BMWs - 31.7 LBS (bimmerworld.com)

    I picked this up around 2 years ago for under $200 at a local autozone. I became friends with the manager there bc he loves e46s and he told me to bring it back before the warranty ends and he'll replace it for me

    I made my own bracket and it fits perfectly. 31lbs and 720cca.
