yeah! your car battery is on (special) relativity steroids! newscientist reports of research conducted on the relationship between special relativity and lead-acid battery performance apparently by 80%. i've not read the paper so i cannot comment. based on the article, this is because lead atoms attract electrons about 60% faster. mass of matter is composed of rest mass which is the mass of it when at rest and relativistic mass which is the mass it induces temporarily when in motion. total mass of matter in motion is the sum of its rest mass and relativistic mass.
