Yeah maybe for things like phone batteries. Grid batteries are a whole different beast. A significant amount of KVARs is necessary to run a grid. Batteries don't scale 1:1 when comparing small Lithium batteries to ones that provide power to a grid.
In other words, the inverter necessary to store the energy from AC to DC uses power, and the same vice versa for supplying power. I'm not thinking of hydrogen, just the application of batteries on a grid.
