  We study the charging process of open quantum batteries mediated by a common
dissipative environment in two different scenarios. In the first case, we
consider a quantum charger-battery model in the presence of a non-Markovian
environment. Where the battery can be properly charged in a strong coupling
regime, without any external power and any direct interaction with the charger,
i.e., a wireless-like charging happens. The environment plays a major role in
the charging of the battery, while this does not happen in a weak coupling
regime. In the second scenario, we show the effect of individual and collective
spontaneous emission rates on the charging process of quantum batteries by
considering a two-qubit system in the presence of Markovian dynamics. Our
results demonstrate that open batteries can be satisfactorily charged in
Markovian dynamics by employing an underdamped regime and/or strong external
fields. We also present a robust battery by taking into account subradiant
states and an intermediate regime. Moreover, we propose an experimental setup
to explore the ergotropy in the first scenario.
