Checking the Battery Service Date

007-4304-003
1. Remove the front cover from the controller enclosure (Figure 3-1).
2. Check the "Battery Support Information" label (Figure 3-8).
The label on the front of the battery canister has three dates:
• Date of Manufacture: — The date the battery canister was built at the factory.
• Date of Installation: — The date the battery canister was installed in the
controller enclosure.
• Replacement Date: — The date you should replace the battery canister.
Look at the Replacement Date. If it is time to replace the battery, install a new
battery canister, using the same instructions as shown in "Replacing a Failed
Battery Canister" on page 54). Otherwise, go to step 3.
Important: Under normal circumstances, replace the battery canister every two
years. Using the controller enclosure in a hot environment (above 35
lowers the life expectancy of the battery canister. Under these conditions, you may
need to replace the battery more often.
