precautionary message (GPM) 99-002 and safety-of-use message (SOUM) 98-
001 for details. Your CECOM LAR or safety office should have copies.
Some of you are taking a fifth option and it’s one you really don’t have. You’re
mixing AA alkaline and AA lithium batteries in the battery holder. Don’t do that!
The battery holder, NSN 6160-01-
385-4358, lets you power your PLGR
with eight AA batteries. It’s easy to
mix together a few alkaline and a few
lithium. But don’t do it. Because the
lithiums last longer than the alkaline,
the mix could lead to leaking or rup-
tured batteries, possibly damaging the
PLGR and causing injuries.
You should also never use the 3.6-
volt AA lithium memory battery, NSN
6135-01-301-8776, in the AA battery
holder. It’s only for use in the memory
battery compartment. If you try to use
it to power the PLGR, you’ll damage
the set!
Check your PLGRs. If you’re using AAs to power them, make sure they are
all
1.5-volt lithium (L91) or
all
alkaline batteries and never a mix.
Generators . . .
A Better Antifreeze
I
f your generator TM calls for ethylene-glycol antifreeze, MIL-A-46153 or
MIL-A-11755, there is now an environmentally safer substitute you can use.
The new antifreeze is propylene-glycol, A-A-52624.
Order a 5-gal can with NSN 6850-01-441-3257 and a 55-gal drum with NSN
Don’t be confused by these NSNs: 6850-01-441-3234; 6850-01-441-3240;
3223.
These NSNs are for ethylene-glycol versions and not the environmentally
safer propylene-glycol. But
all
are covered under the same new standard,
A-A-252624.
Don't use the 3.6V lithium
Battery holder powers
PLGR with AA batteries
hen it comes to powering your AN/PSN-11 precision lightweight
global positioning system receiver (PLGR) for handheld operations, you have
four battery options:
Two types of BA-5800s have been deadlined,
including those manufactured by Ballard under
CECOM contract DAAB07-90-C-C024 and by
boil, boil,
bubble, bubble,
mixing
batteries
will cause
great
trouble
