  We demonstrate an asymmetry between the beneficial effects one can obtain
using non-local operations and non-local states to mitigate the detrimental
effects of environmental noise in the work extraction from quantum battery
models. Specifically, we show that using non-local recovery operations after
the noise action can in general increase the amount of work one can recover
from the battery even with separable (i.e. non entangled) input states. On the
contrary, employing entangled input states with local recovery operations will
not generally improve the battery performances.
