Based on the previous success of adding ultra-fine carbon-PVA (polyvinyl alcohol) colloid solution to restore the performance of weak batteries, a large scale test programme of practical batteries including those used in forklift, golf cart, taxi cab, truck and bus applications from 150 companies was carried out. More than 95% of the tested batteries exhibited excellent recovery in performance parameters including the specific gravity, voltage and operation time (Ah capacity). The work reported here includes basic research studies to understand better the beneficial action of the carbon-PVA colloid additive.
