Why UPS’s batteries gets damaged over the time?
In: Technology
A lead acid battery (in most UPS’s) store electrical energy as a chemical potential. As in, chemical reaction inside the battery creates free electrons (electricity) which you then use. When we want to store electricity, we reverse the process (add electrons) and the battery regenerates a certain amount of chemical potential again.
This process isn’t perfect, the chemical reaction in both direction has losses (inefficiencies) and degradation of the chemicals themselves.
Over time, this cycling reduces the battery to an ineffective state and requires replacement.
