According to a recent Buzzfeed article, there is a new method to test the strength of batteries. By observing the bounce of batteries, you may be able to tell how much life is left in them.
“If you want to test that theory, you need to, you know one try will not do it,” physics professor University of South Florida’s Dr. Sarath Witanachchi said. “You’ve got to try maybe twenty times and see is there a pattern.”
USF engineering student Alex Tremper believes that such an experiment has already taken place and conclusions have already drawn.
“Princeton researchers have demonstrated that this can only tell you whether batteries are fresh, not whether they are charged enough to allow a device to function,” said Tremper.
Knowing whether or not batteries are fresh, can be useful in preparation for storms with potential, to cause power outages, like Hurricane Hermine. Battery-powered appliances can alleviate some of the inconveniences power outages bring.
“We had lots of flashlights, we actually had a battery-powered TV, radios, hand-held video games, things like that,” Tampa Bay Area resident Spencer Adkinson said.
Tremper and Dr. Witanachchi claim that a more reliable way to test a battery is with a voltmeter, which measures the voltage across the terminals of the battery. If the voltage drops below the amount the device requires, then the device will not function.
“This decrease typically happens slowly throughout the life of the battery with a dramatic decrease towards the end of the battery’s life,” Tremper stated.
