Why do batteries feel lighter when dead?
Dead alkaline batteries do bounce more than fresh batteries , though; this is due to changes in the “texture” of the zinc anode material as the battery is discharged. It’s possible that this change in “bounciness” (technically, coefficient of restitution) could be perceived as a change in weight.
Why do batteries bounce when they are dead?
Electricity is generated by a chemical reaction inside the batteries as zinc changes to zinc oxide. Initially, a layer of zinc surrounds a brass core in the battery like a donut around a hole. As the battery discharges, the zinc donut gradually changes to zinc oxide. That is what gives the battery its bounce. ”
What happens if you drop batteries?
