An implantable neurostimulation (INS) device includes a non-rechargeable battery, a rechargeable battery, an antenna, an inductive coil, a neurostimulation module and a telemetry module. The neurostimulation module produces neurostimulation signals for delivery to target neural tissue, and the telemetry module wirelessly communicates with a non-implantable device using at least one of the antenna and the inductive coil. The non-rechargeable battery provides power to the neurostimulation module, and the rechargeable battery provides power to the telemetry module. The INS device also includes a charge module that charges the rechargeable battery in dependence on signals received from a non-implantable device via the inductive coil. Additional modules, such a sensor module, can be powered by the rechargeable battery. Additionally modules, such as controller, can be powered by the non-rechargeable battery. The rechargeable battery can power components normally powered by the non-rechargeable battery, when a capacity of the non-chargeable battery falls below a threshold.
