1. A method for controlling a battery, comprising:

  • training parameters for a battery capacity prediction model based on usage pattern information that correlates usage of similar batteries with capacity information for the respective similar batteries, wherein the model characterizes a capacity decay rate in accordance with a present value of the battery capacity;

    predicting future battery capacity for a battery under control based on the battery capacity prediction model and a present value of the battery capacity; and

    controlling one or more operational parameters of the battery under control based on the predicted future battery capacity to extend the battery'"'"'s usable lifetime.
