Abstract
A small micro-controller with other associated circuitry is embedded in the housing of a battery to digitally display a battery's state on its exterior. The measurements computed or displayed can include indications of any state of the battery including, but without limitation, indications of (1) the amount of time remaining until the battery's current charge is exhausted, (2) the amount of power remaining in the battery (3) including for example a percentage remaining, (4) the amount of time until the battery will no longer accept a charge, (5) the amount of shelf life remaining (6) the amount of shelf life remaining until the battery charge depletes to a certain threshold and (7) the current voltage being delivered (8) the amperage available.
