John,
If you spend $3,000 on a forklift battery with the life expectancy of let's say 3 years, and my system can get you an additional 1 to 3 years out of that battery for say 40% of the cost of a new battery, why not save the 60% and put those savings into purchasing something else. The 30% to 40% cost is for the initial desulphation process. The preventive maintenance done yearly is considerably less expensive. As for battery warranties, they are figured in the favor of battery manufacturers. Let's say you buy a 60 month battery and it lives up to 41 months. The warranty is so pro-rated that when taking the months used against the full retail price of a battery you end up paying about the same money as if you purchased the batter at the sale price. This makes the manufacturer happy. What makes us happy is to help the client exceed the warranty. Let me assure you it can be done with our service and the right maintenance plan for batteries. Also, as the battery gets weaker, the amp hours are reduced and that affects the productivity of the user which is an additional loss of revenue for the client. By our desulphating the battery we help reduce loss of amp hours and keep the clients productivity up. I hope this helps.
