Lucent Technologies Round Cell Batteries
7 - 14 Operation and Maintenance Issue 3 December 1999
Check Battery Connections, continued
Corrosion Corrosion from electrolyte is usually caused by careless handling of the
hydrometer syringe when measuring specific gravity. Green or blue
copper sulfate on a part, usually an intercell connector or a terminal
detail, indicates that electrolyte has penetrated its lead coating and is
reacting with the copper. Any such part other than a post should be
replaced and all associated surfaces treated.
Opening Battery
Connections
Use the following insulated tools for making connections and discharge
all static electricity from your body before performing any work on or
around the Round Cell batteries:
• Torque wrench capable of measuring 150 inch-pounds
• 1/2-inch box wrench
Torque connections to 150 inch-pounds maximum.
DANGER
An explosion could occur when sparks are created near the battery
string.
Caution
Over-tightening of the connections could break lead posts and
connector bolts or strip the bolt and/or nut threads, resulting in loose
connections.
