I guess it depends on the type of battery, with ol' lead batteries you used density meters (hydrometers) to measure charge level, and to more dense liquid corresponded higher level of charge.
- gpm 3y agoWhat's happening there is sulphur and oxygen is moving out of solution onto the solid lead plates. The mass of the liquid changes, the mass of the battery as a whole stays the same (apart from e=mc^2 as mentioned in a sibling of your comment).
- jaclaz 3y agoSure, just having a little fun on the topic that I don't think is to be taken seriously.
