CAUTION
When removing and carrying batteries, be careful not to hit the battery
against the sides of the vehicle or other structures. The battery
casing can be cracked if struck by or against other objects.
(c) Set battery down carefully on a board or wooden platform.
b. Corrosion Inspection. Aside from a careful, general inspection of the condition
of the battery, battery cables, battery box, hold down supports, and fasteners, a
through inspection of the battery cables, terminal and fasteners should be made
to detect the presence of corrosion.
(1) Effects of corrosion. As acid eats away terminals, terminal posts and
exposed cable, corrosion builds up on these surfaces. This corrosion
creates a resistance to current flow and restricts proper flow of current to
the starter and the equipment electrical circuit. On equipment having
voltage regulators, resistance caused by corrosion prevents the battery from
receiving a sufficient charging current. After repeated battery use, this
results in an undercharged, sulfated battery.
(2) Battery System Inspection. Inspect battery system for corrosion as follows:
(a) Inspect cable ends for corrosion and general condition. Check for worm
insulation, breaks and buckling. Replace all unserviceable cables.
Clean as required.
(b) Inspect battery terminal posts for corrosion and overall general
condition. Clean as Required. After cleaning, check that cleaned cable
terminals fit properly on the cleaned battery posts.
(c) Inspect battery, battery box, hold downs, clamps, supports, fasteners,
adjacent equipment, etc. for corrosion and general serviceable
condition. Clean, repair and/or replace as required.
