Yes, electrons weigh something. However, when charging a battery, one does NOT add electrons to the battery. They are moved from the low energy side of the battery to the high energy side of the battery. During discharge, the charge leaves one side of the battery, moves around in the external circuit and comes back to the battery where it is stored in the low energy side. Net change in weight is exactly zero.

Nicely said. 😃
A charged battery weighs slightly more than a depleted battery, due to its higher internal energy state. By m=E/c2 m = E / c 2
i was almost expecting a few grams lighter after charged
The short answer is no, no it doesn't
That's the short answer. 🙂
I had to laugh at this. There will be zero change.
