Inspection and Periodic Maintenance
This procedure should be performed annually or whenever batteries need to
be replaced.
1. Place the battery pack in Maintenance Shutdown condition (Para-
graph 4.6.2).
2. Open the front doors of each battery pack and visually inspect the inside
of the cabinet for:
a.
Leaking acid.
b.
Corrosion on frame and electrical parts.
c.
Loose or discolored electrical connections, especially around
the cable connections.
3.
Disconnect all the battery cable connectors.
4.
Each battery tray is held in place by two bolts that fasten it to a slide.
Remove the bolts from one tray at a time and very carefully pull the tray
forward. Care should be taken that the tray doesn't come all the way out.
The tray is heavy weighing as much as 200 pounds (91 kg) or more.
5. Use a lift hand truck to remove the tray completely from its slide.
CAUTION
The battery tray weighs as much as
200 lbs (91 kg). Use lift hand truck to remove it.
6. Inspect each battery post for corrosion or discoloration. If post is
discolored or corroded remove battery cable and clean the post and cable connector
shiny bright. Replace cable, torque cable connector bolt to the battery
manufacturer's recommended torque*, and apply a generous amount of grease
(Dow Corning silicone grease or equal) to the battery posts and connectors.
* Torque specifications may be found on the battery itself or in specifications at the end of this
section.
