Strange. Never heard of a lithium battery for regular (non-electric) cars. Lithium isn't capable of high current. That's why power tools used NiMh.
My new battery is physically smaller than my OEM BMW battery, so density is higher. The correlation of that is if it were the same physical dimensions, it would be lighter. Energy density is increasing so batteries are getting lighter, per volume.
