Lead Acid Batteries are on their way out at a slow pace. There are several reasons the Lead Acid Batteries should be phased out. Lead mining is very dangerous and some plants are being closed without new ones being reopened (mostly health reasons). Most companies are polluting the water supplies with contaminates that are washed from the tops of the Lead Acid Batteries and the worst is the Lead contamination to the human health when working on Lead acid batteries. OSHA (part of the American Government) monitors the safety of battery repair shops. The lead from the drill work has been known to enter the body and creates many problems to the internal organs. Hepa vacuums must be used during repairs. Lead Paint has been a recent problem with toys from China. Lead is just not healthy and the governments of all countries have been easy on the lead acid battery laws for a long time because there is no other infrastructure for powering electric trucks at this time. Hydrogen Fuel Cell is the way to go in the near future and complete ultra-capacitors (maxwell) after that.
