hen it comes to the 12-volt, lead-acid batteries that get your 5-KW tactical quiet
generators up and humming, you have several choices.
The cheapest, and the one that requires the most maintenance is 2HN, NSN 6140-
00-057-2553. With this battery you’ll have to keep an eye on the fluid levels, add
fluid when needed, and risk acid leaks and spills.
The current favorite battery, at nearly twice the price is the Optima D51R, NSN
6140-01-529-7226. This is a maintenance free, sealed, spill-proof battery. Its case is
plastic, not rubber like the older battery, and it’s a bit smaller. But when it comes to
eliminating fuss and muss, this battery is your baby.
There is also a maintenance-
free battery for the 10-, 15-, 30-,
and 60-KW TQGs, the Optima
800U, NSN 6140-01-374-2243.
For these batteries to fit right in
the 15-, 30-, and 60-KW TQGs,
you’ll need adapter tray, NSN
With the new Optima D51R for
the 5-KW, the Optima 800U for
the 10-KW, and the Optima 800U
with adapter tray for the 15-, 30-,
and 60-KW TQG, all batteries for
the TQG fleet of generators can
be maintenance free.

AN/PRC-148(V) MBITR…
guys!
guys!
c’mere!
he
really
pulled off
his
finger!
T
he microphone-handset connection on the AN/PRC-148 (V) multiband
inter/intra team radio (MBITR) needs to be fooled if you want to connect
the improved tactical headset (ITH) to it.
The microphone-handset connection has six pins. One pin is in the mid-
dle and five surround it. The pin in the middle has a 5-volt current running
through it. This current lets you connect a powered electret microphone.
However, the Bose Tactical TriPort ITH needs to operate either unpow-
ered or powered by 12 to 24 volts. The low five volts put out by the MBITR
center pin causes the ITH to switch back and forth between powered and
unpowered mode leading to unreliable operation.
So fool the MBITR into thinking it’s connected to a generic handset like
the H-250 by putting a small piece of electrical tape over the center pin on
the microphone-handset connection. When the center pin is covered, getting
good comms with the ITH should be no problem.
hmmm…
The microphone/headset
connector has six pins, so…
…cover middle pin
with electrical tape
