A method for extending the storage lifetime of a rechargeable battery located in a device is disclosed. The battery lifetime extension method includes providing a device that derives its power from a rechargeable battery. When the device is powered off by a user, a computer implemented program utilized by the device automatically powers up the device into a lower power mode upon expiration of a variable duration timer monitored by the computing unit that continuously repeats according to a programed duration cycle. The computer implemented program then evaluates a state of charge of the rechargeable battery, determines whether the state of charge of the rechargeable battery is above or below a variable programed threshold, and causes the rechargeable battery to remain in a low power state until a charge is applied to the rechargeable battery.
