Systems and methods for runtime update of battery coefficients are described. In an illustrative, non-limiting embodiments, an Information Handling System (IHS), may include: a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive a battery configuration policy from a remote server; and transmit at least a portion of the policy to a battery management unit (BMU) at runtime, where the policy comprises one or more battery coefficients.
