Hey guys ive been having problems with my car battery and my capacitor isn't helping much either. i heard this battery equals out to 100 capacitors and solves all the battery problems! i don't know how to find the size of the battery and not sure if this would fit in my z or not. i heard the + - were switched or something. here is the link to the battery, help would be appreciated, thank you.
