A system for increasing the life of a battery cell by limiting the charging of the battery to less than full charge in response to a predicted electricity draw of a connected device being less than the full capacity of the battery before a predicted recharge will occur. The current draw of the connected device may be affected by the amount of time before a next recharge and environmental factors. The system may further comprise one or more sensors to gather data pertaining to environmental conditions that may be used in the calculation of a charge termination value. The charge termination value is an amount of charge to power the device for a duration of time at least until a predicted recharge begins.
