An implantable cardiac device has a pulse generator configured to generate electric shocks for delivery to a patient's heart. The device has an output capacitor, and connected charging circuitry. A first battery is switchably coupled to the charging circuitry, and has a high current flow rate to rapidly charge the capacitor. A second battery is switchably connected in parallel to the first battery, and is operable to recharge the first battery. A detector coupled to the charging circuitry detects when the recharging current is above a predetermined threshold indicative of abnormal recharging. A controller is programmed to enable the charging circuitry to produce the shocks, and to disable the second battery whenever an abnormal recharging current is detected. The controller may operate to connect the batteries on anti parallel whenever an abnormal recharging current is detected.
