ew mechanics and not-so-new mechanics, one extra twist to the wing nuts on the
holddowns for the sealed lead-acid battery (SLAB), NSN 6140-01-286-6294, and
you might hear a crack. That’s the sound of the battery snapping.
Hand tight on the wing nut is tight enough. The battery tabs are not that sturdy, so
they crack easily when the wing nut is tightened too much.
If you’ve already heard that sound,
it means you’ve broken another battery
locking tab. That makes the SLAB
unserviceable.
Pay attention and follow the instructions
on the battery’s caution label. Don’t work
up a sweat when tightening the wing nuts.
If you break a tab, you’ll be replacing the
SLAB battery at $690 a pop.
Remember,
for
an
unserviceable
battery there is no ‘wing and a prayer’
solution—just replace it.
