Additional Studies on the Degradation of VRLA Batteries and the use of the Catalyst or Alternative Charging Techniques to Reverse Degradation

Allan Williamson

Bruce Dick

For the last two years, we have been informing this august body about our testing and evaluation on the use of internal precious metal catalyst to enhance the performance and life of VRLA (Valve Regulated Lead-Acid) batteries. This year while we will bring everyone up to date with the latest results after two years as a production product. In addition I will report that, as a result of our testing, it is possible to improve many older VRLA product by retrofitting with an internal catalyst. We will also show that it is possible to reverse the negative plate sulfation that has caused performance degradation by boost charging.
