Bounce denotes battery health

Written by Charlie Quigg for Chemistry World

Inspired by a YouTube video, scientists in the US have confirmed that a simple bounce test can be used as a technique to indicate charge in a battery.

Alkaline AA batteries are one of the most common battery types and there are a range of approaches to assess the charge in these batteries, often entailing electronic indicators. Now, a team led by Daniel Steingart of Princeton University have correlated the coefficient of restitution (COR), a measure of bounce, with batteries at various charges and determined their charge to a similar degree of accuracy as in situ energy-dispersive x-ray diffraction (EDXRD).
