1.
Place a good battery in parallel to the dead battery,
positive to positive and negative to negative.
2.
Attach the charger’s jumper cables to the good or the
bad battery, positive to positive and negative to negative.
You can avoid some minor resistance losses by connecting
to the dead battery.
3.
Charge for about
15-20 minutes. That pushes
amperage into the dead
battery, raising the
voltage high enough to be
sensed by the charger.
4.
Remove the good battery.
5.
Now charge the
bad battery as you
would normally.
Dear Half-Mast,
I heard there’s a
way to keep my unit’s
Hawker batteries in
the fight a little longer,
even if it seems like the
batteries are dead. Is
that true?

TARDEC released a video with a trick you
can use that bumps up the battery’s voltage
enough that the charger can do its job.
For more details, have your mechanics watch the battery video on milTube:
The trick starts at about the 2:46 mark.
