Do Batteries Gain Weight After Charging? The Truth About Battery …
Batteries don''t weigh more when charged because mass is an intrinsic property that doesn''t change, while weight is affected by gravity. Charging a battery adds electrical energy, not mass. Despite the notion, the mass is conserved according to the law of conservation of mass, and energy is conserved according to the law of conservation of...

electricity
Once the battery is fully charged it will not accept any more energy (current) from the charger, since all the energy levels that were depleted when empty are now at their highest level. For example in a Lithium ion battery when all the ions have arrived at the proper electrode the resistance to more current becomes very large, but not infinite ...
Settle an argument. Do batteries get heavier when charged?
However, objects do become heavier when they have more energy (based on E = mc 2 or m = E/c 2), so a 100 kWh battery gains 4 millionths of a gram when it''s full. In reality you''ll have a bigger change in mass from rubber wearing off of your tires and dirt from your shoes getting on the floor mats.
