David is a forklift dealer. Every year he spent thousands of euros buying new cells and batteries to replace in his rental machines, usually due to inadequate maintenance by his customers. Since he began doing the MACBATEC maintenance regeneration, he no longer has to replace so many batteries, which has drastically cut down his costs. His customers are much happier now because they realised that batteries last longer and trucks are less likely to need repairs due to electrical damages caused by low and uneven voltages. Not only has David increased his profits, he has also lowered his prices, thus benefitting his customers as well.
