Methods and apparatuses, including computer program code are disclosed herein that provide adaptive battery protection. A method includes disabling a timer, when a current drawn by a battery-powered device from a battery is less than or equal to a lower current threshold. When the timer is disabled, the battery may remain connected to the battery-powered device. The method further includes enabling the timer when the current drawn from the battery is greater than the lower current threshold and less than an extended current threshold. When the timer is enabled, the timer may allow the battery to remain connected to the battery-powered device until the timer expires. The method further includes disconnecting the battery when the timer expires or when the current drawn from the battery exceeds the extended current threshold.

Adaptive battery protection

An apparatus comprises a transformer coupled to a mains power, a backup power source comprising a first battery, a first power supply line switch configured to switch the power source between the backup power source and the mains power, a connecting interface coupling the power source to an external electronic device comprising a second battery which is rechargeable and a second power supply line switch which is configured such that the external electronic device is able to be powered by either the power source or a second battery, and a charging detector configured to detect the availability of the mains power, wherein the first power supply line switch is further configured to couple the backup power source to the external electronic device via the connecting interface when the mains power is not available such that the first battery is able to deliver power to the external electronic device.
