That is a very good and often overlooked point. So in average on a flight one has to calculate maybe with 60% weight of kerosene, while the battery keeps 100% of its weight during the entire flight.

It gets worse with lithium air batteries that actually gain weight as they discharge because of the formation of solid oxides from the air. Argonne are reporting 1200Wh/kg in the lab though so still worth it.
