TimeKeeper
The NI series of controllers use a combination lithium battery and clock crystal package called a
Timekeeper. Only one Timekeeper unit is installed within a given NI controller. The battery can be
expected to have up to 3 years of usable life under very adverse conditions. Actual life is appreciably
longer under normal operating conditions. This calculation is based on storing the unit without power in
50° C (120° F) temperature until battery levels are no longer acceptable. The part number for a
replacement battery is 57-0032.
