All APC batteries should last three to five years. Below are some guidelines to ensure optimum life expectancy:
1. Make sure that the APC UPS
battery is kept in a cool, dry location with plenty of ventilation.
Ideally, the temperature where a UPS is kept should not exceed 75° F
(24° C). Also, for ventilation purposes, leave roughly one to two inches
on each side for proper airflow.
2. Only perform runtime
calibrations on the UPS one or two times a year, if necessary. Some of
our customers want to check their systems to verify that their runtime
is sufficient. However, consistently performing these calibrations can
significantly decrease the life expectancy of your APC battery. Click here for more information on runtime calibration.
3. Do not store APC batteries
for extended periods of time. New batteries can be stored for 6 to 12
months. After this period, the battery should be used or it will lose a
great deal of its charge. It is not advisable to store batteries that
have already been in use.
4. Do not exceed 80 percent of
a UPS unit’s rated capacity due to the reduction in run time. When
loads increase, runtime lessens. In the event of a power failure, a UPS
loaded to full capacity will drain and discharge its battery quickly and
will lessen the life expectancy.
