Is it grammatically/techinically correct to say "energy restitution"?

Question

Isn't the convention of stating that is "coefficient of restitution"?

Answer 1

1. energy restitution is the same as energy replenishment or return to a certain specified level like in the case of batteries or raising the weights on the gradfather clock.

2. Coefficient of restitution could apply to the efficiency of recharging as a ratio of energy accumulated to energy supplied. The coefficient will be less then 1 due to losses.
