An apparatus and method for allowing an operator of a portable infusion device continue to operate the device after the primary battery source becomes depleted. The invention contemplates providing a secondary, rechargeable battery in addition to the primary battery, to allow the infusion device to operate even in the instance of a sudden drop in primary battery voltage. The apparatus includes a housing accommodating a syringe, where the syringe contains a liquid to be infused. Also included is a motor, a drive system operatively connected to the motor, where the drive system advances a piston of the syringe in order to expel the liquid from a barrel of the syringe. A power source is in electrical contact with and supplies power to the motor. The power source includes a primary battery module, and a rechargeable battery module, wherein the primary battery source supplies power to the rechargeable battery module. The result is a fail-safe system of alerting the user of low or critical battery conditions.
