Enables an infusion pump battery capacity management and battery charge alert system and method including an infusion pump with rechargeable batteries, a controller, a computer and a user interface. The infusion pump accepts a programmed infusion and selects a battery capacity assessment option to determine one or more recharge options of the batteries, and may optionally select a program delay option to execute an infusion delay and later select the battery capacity assessment option. During the battery capacity assessment option, the infusion pump calculates an anticipated power capacity requirement to execute the programmed infusion, calculates a remaining battery power capacity, compares the calculated anticipated power capacity requirement to the calculated remaining battery power capacity, and determines whether the infusion pump is able to fully execute the programmed infusion based only on the remaining battery power capacity or whether a recharge is required.
