BatteryVitamin promises to rejuvenate your old lead acid battery and lengthen its lifespan. It does this by doing some ‘nano’ stuff to help keep the plates fresh by cutting down on the electroplating process. It’s apparently nothing to do with sulfating, which is a well known alternative method. Anyway it seems that it stops the corrosion of the plates in the battery. If it works as advertised it could be useful for the electric vehicle market, eh?
What it all boils down to is that even though battery lead may be about 150,000 times less soluble than electrolytic lead, after about 3-8 years in service, a lead-acid motive power battery will have been exposed to an amount of electroplating at least comparable to the work performed by electrolytic refining and electroplating cells over a period of several hours. Batteryvitamin has a very specific functionality and is thereby able to cut down electroplating and to extend battery life without otherwise significantly affecting battery operation,
