“The main message is quite simple: batteries are just as badly affected by the cold as they are by the heat”
We were delighted to partner with Mike McDonagh, Best Mags Technical Editor, to write this excellent piece on how temperatures affect batteries.
As temperatures reduce everything moves more slowly, including the chemical reactions necessary for batteries to charge and discharge. As ions slow down more energy is required to get them moving again.
BEST’s technical editor, Dr Mike McDonagh, takes a look at the effect of low temperature on lead-acid battery operation and charging and explains how to compensate for changes in operating temperature.
