Best Battery Replacement Options

[e46mpwrd]

For the Anti-Gravity guys, did y'all have to build your own bracket?

The one I have is direct replacement using stock tray. Weighs ~14lbs .

Edit: I have Antigravity H7/Group-94R Car Battery - 60 Ah

Street car the OE Exide battery IMO, normally get a solid 10 years if looked after. Even when crappy shops do their best to kill it

I usually have the CTEk hooked up. I just had it off for a month with the car sitting. I had to use the restart button today. My trunk interior is pretty much gutted so it is easier to get to.

Same here. Battery is always on a charger.

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

Why would you hate it for a street car?

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 street car with options (radio, heated seats etc) then just go for OEM equiv (H7 i believe).

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.

I have a Antigravity 60AH H6. I love it. Never had an issue.

I have a Antigravity 60AH H7. I love it. Never had an issue.

which battery did you get? their 60AH option seems comparable in capacity to at least the H5 mini battery

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

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.

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.

I recently bought a Champion H7/94R battery. Perfect fitment.
