1. A method of causing a first battery to exit a battery storage mode, the method comprising:
receiving, while the first battery is in the battery storage mode, a wake up signal indicating a power up event;
generating an exit signal in response to the wake up signal, to cause the first battery to supply power to a first processing circuitry;
waiting a predetermined time period following a predetermined edge of the exit signal;
determining, after expiration of the predetermined time period, whether the first battery is supplying power to the first processing circuitry; and
generating a second exit signal in response to determining that the first battery is not supplying power to the first processing circuitry;
wherein, in the battery storage mode, a second battery provides power to second processing circuitry to perform the method of causing the first battery to exit the battery storage mode.
