Checking the battery service date
Note: Replace the battery whenever it fails to hold a charge or every three years. Using
the controller unit in a hot environment (above 35
º
C or 95
º
F) lowers the battery
life expectancy. Under these conditions, you might need to replace the battery
more often.
To check the battery service date, do the following:
1 Remove the controller unit bezel, as shown in Figure 6 on page 11 .
2 Check the Battery Support Information label, as shown in the following figure.
Figure 14. Checking the battery service date
The Battery Support Information label on the front of the battery has three dates:
• Date of Manufacture – Date the battery was built at the factory
• Date of Installation – Date the battery was installed in the controller unit
• Replacement Date – Date to replace the battery (see the note at the beginning of
this section)
3 Look at the replacement date and do the following:
• If it is time to replace the battery, install a new battery using the procedure
described in
"Replacing a failed battery" on page 35 .
• If it is not time to replace the battery, replace the controller unit bezel, as shown in
Figure 7 on page 11 .
