he J-6362/U 24-volt ve-
hicular cable, NSN 5940-01-
427-9395, lets you operate
the PP-8444 battery charger
from a vehicle’s NATO slave
receptacle.
But sometimes you plug the
cable up and get nothing.
Before you trash the cable,
check the AC and DC power
switches on the charger. Make
sure the AC power switch is
OFF and the DC switch ON.
If the DC is on and you’re still not getting power, turn the switch on and off
several times to help clean the contacts.
Still nothing? If you have compressed air, like the canned air used for cleaning
keyboards, use it to clean the contacts.
Still
nothing? Make sure both ends of the cable are clean by removing them,
cleaning away any debris and wiping off the contacts. Then reseat them.
If you’re still not getting 24 volts of power to your charger, troubleshoot the
charger to find out if the cable or the charger is the problem. Troubleshooting
procedures are in Para 4-2 of TM 11-6130-489-13&P.

Rechargeable Batteries . . .
quipment that uses more than one lithium-sulfur dioxide (LiSO
2
) battery, like
the AN/PRC-104 radio, and the AN/PSN-10 GPS receiver, needs to have those
batteries replaced in matched sets.
To be considered a matched set, LiSO
2
batteries must be made by the same
manufacturer and must have the same contract number and date code.
If you follow the first in, first out rule when drawing batteries from your
supply, you should be getting matched sets.
Lithium-Sulfur Dioxide Batteries . . .
Replacing both batteries of a set and using matched sets ensures the same
approximate state of charge for both batteries. That minimizes problems during
use.
Replacing one battery at a time or using non-matched sets means one battery
will be discharged before the other. This could cause voltage reversal and a
ruptured battery. It could damage your equipment and even injure you.
Also, never mix LiSO
2
batteries or other non-rechargeable batteries with their
rechargeable equivalents.
we have the
same
manufacturer
,
the same
contract
number
, and the same
date code
.
sigh.
we're a
matched
set
.
wait!
i'm
still
good
!
it's the
same old story
, he
forgot to
check the
ac
and
dc power
switches
