Abstract
Systems and methods that may be implemented for time-based management of storage memory controller (e.g., RAID controller) backup battery life in information handling systems by limiting the backup battery system operation time in order to save energy, reduce the impact of leakage current, and prolong memory controller backup battery shelf life while at the same time meeting requirements of back-up time for storage/server applications. The disclosed systems and methods may be implemented, for example, by providing a battery system controller that implements a pre-set memory controller backup battery operation time, in combination with a hardware-controlled mechanism that extends backup battery system operation time by disabling one or more current leakage paths within the storage memory controller circuitry.
