Operators
Check the batteries weekly. Take off the
battery caps and make sure the electrolyte
is
1
∕
4
inch below the filler neck or ledge. Add
distilled water if necessary.
If corrosion has formed around the ter-
minals, clean it off with the wire brush in
your tool kit or a scouring pad. Neutralize
any corrosion on top of the batteries with a
mixture of
1

pound of baking soda to 1

I
f you don't respect your Avenger's batter-
ies at PMCS time, don't expect to do much
firing.
To do their job, Avenger batteries
must be in peak condition.
Keeping Avenger batteries strong takes
the efforts of both repairmen and operators.
Repairmen
Repairmen, check the batteries with the
hand-held battery load tester, NSN 6130-
01-447-7294. It will tell you the battery's
state of charge or if it's bad. To charge a bat-
tery, start the HMMWV and run it for 20
minutes at 1,200-1,500 rpm. Then test the
battery again and charge longer if neces-
sary. If a battery is badly discharged, it will
be easier to charge it with a battery charger.
If you add distilled water to a battery,
charge the battery before you test it. That
mixes the water and electrolyte so that you
get a good reading.
Once the Avengers are properly charged,
have the operators charge the batteries for
20 minutes during weekly services.
Every 6 months, test the HMMWV
charging system to make sure the electrical
system's working. Para 2-29 in TM 9-2320-
280-20-1 has the instructions.
