Charged NICAD batteries discharge during storage.
The rate of
discharge varies with storage temperature.
You must verify the
storage time and charging interval at the time of issue. No battery
should be issued that has been charged and stored for more than 10
days. Where storage temperatures are above 70€ F (21€ C) or below
32€ F (0€ C), batteries should not be issued that have been charged
and stored for more than 5 days. If a battery has been unused or in
storage for 6 months or more, charge as per TM 11-6130-392-12.

Testing and Troubleshooting the LD/R.
The LD/R test procedure provides a systematic checkout of the LD/R using the
The LD/R test
consists of 12 tests (including the initial test setup), which provide a
complete system checkout. Appendix B, an extract from TM 9-1260-477-34-2,

test, followed by the appropriate troubleshooting tables.
illustrates the testing and troubleshooting format used for the G/VLLD. TM
9-1260-477-34-2 provides similar testing and troubleshooting procedures for
each of the 12 tests.
The test procedures locate faults within the unit under test. Perform the
steps listed in the appropriate troubleshooting table only after you see the
troubleshooting only when directed by a test failure.)
If a retest shows
that the troubleshooting procedure has not fixed the fault, send the G/VLLD
to depot for repair.
If the G/VLLD was referred to direct support due to a suspected
optical misalignment, perform the operator boresight test as per TM
9-1260-477-12. If the G/VLLD fails the boresight test, send it to
depot for repair/ disposition. If the G/VLLD passes the boresight
test, perform the LD/R test procedures.
