Without getting into a lengthy discussion like on a previous thread the 100+ year old Edison Battery used in the first electric cars has a life span of 100 years, can be fully discharged or highly overcharged without damage and with a top off of some distilled water away you go.
Unfortunately after a new method to increase energy density was developed Exide purchased the patent for that process and then shut down production. You can still buy the older technology though. Seems Exide did not want any competition from a 100+ year lifespan battery.
Too bad for Tesla it is a nice looking car and the motor is very well designed but like all electric vehicles the batteries suck and Super Caps are not the answer.
Could you please post the thread title or a link to that thread?
Can you give us a link or a clue of the name of the thread for those who missed it?
