1. An implantable device containing a plurality of batteries, the plurality of batteries comprising:
at least one first non-rechargeable battery;
at least one second rechargeable battery;
an Implantable Cardioverter Defibrillator (ICD) unit;
a Cardiac Contractility Modulation unit; and
a controller,
wherein the controller is configured to:
provide power for life-saving function operation by a first, non-rechargeable battery;
provide power for non-life-saving function operation by a second, rechargeable battery;
measure an electric power level of the rechargeable battery; and
compare the rechargeable battery level to a first threshold;
if the electric power level of the rechargeable battery is less than the first threshold, then sustain ICD module operation using electric current from the rechargeable battery and not sustain Cardiac Contractility Modulation operation; and
compare the rechargeable battery level to a second threshold, wherein if the electric power level of the rechargeable battery is less than the second threshold then sustain the ICD module operation using electric current from the non-rechargeable battery.
