The disclosure is directed to transmitting power source usage information regarding a power source of an implantable medical device (IMD) to a remote networking device via a network. The IMD operates on power supplied by a power source, such as a battery, within the housing of the IMD. The use of the power source may be monitored remotely in order to maintain therapy. Power source usage information may include power source recharge patterns such as frequency of recharging events, length of recharging events, period between recharging events, discharge state of the power source, and degree of coupling between primary and secondary coils during recharging. The IMD, or an external device used with the IMD, may generate, store, and transmit the power source usage information to the remote networking device. Action requests may be transmitted from the remote networking device via the network based upon the power source usage information.
