Keep battery pack charged
he internal battery pack of
your uninterruptible power
supply (UPS), NSN 6130-01-
430-2887 or NSN 6130-01-
421-7678, is supposed to give
you time to shut down your
attached equipment during a
power failure.
But how much time you get,
if any, depends on the condition of the two 12-volt lead-acid batteries in the
battery pack, NSN 6130-01-436-3328.
And the condition of your batteries depends mostly on how they are stored.
So always fully charge the batteries before long-term storage by operating the
UPS for at least 24 hours at temperatures between 0–70
°
F.
You also need to charge batteries for 24 hours every three months during long
term storage. After charging, check for swelling.
Swelling means the battery should be replaced.
If batteries are stored some place hot, they need to be charged more often or
they can be damaged. Try to store batteries in a cool place.

atteries come and batteries go. But
you are not letting go of some that
should have gone! That’s because
you’re not paying attention to safety-
of-use messages (SOUM). The batter-
ies listed in these SOUMs could cause
severe injury or destroy equipment if
not handled properly.
Three messages that some of you are
ignoring are:
