May 9, 2025 | HSM CEX7S / 4769 | Update to Battery Replacement Information
The useful life of the batteries mounted in an IBM 4769 that is continuously powered on is nearly the same as the useful shelf life of the batteries. The actual life of the batteries is anticipated to be in excess of seven years. IBM recommends changing the coprocessor batteries as a planned maintenance activity every three years. However, if the coprocessor is left unpowered for long periods of time, battery refresh should be done sooner than three years. Before changing batteries, ensure that the replacement batteries measure 3.0V or higher and have not been in inventory for a long period of time.
