It sounds like a pitch on the television show “Shark Tank.”
Lisa Rinaldo and her father John Ebbinghaus started the business Prohm-tect, which makes a paste that can be put on batteries and power cells to make them last longer.
Ebbinghaus came up with the idea when he was working for a company that made parts for U.S. Navy ships. His company didn’t want to produce his paste, so he held onto his idea for 20 years.
