Troubleshooting and Maintenance

Table 1 Troubleshooting

Category

Symptom

Possible Cause

Remedy

Performance

Reduced operating time

Normal life cycle

Replace battery bank when (or before) capacity

drops to unacceptable levels.

Defective cells

Test and replace battery as necessary.

Excessive voltage drop upon

applying load

Excessively cold battery

Carefully warm up the battery.

Undersized cabling

Increase cable ampacity to match loads.

Loose or dirty cable

connections

Check and clean all connections. Physical

damage on terminals may require the battery

to be replaced. Replace hardware as necessary.

Undersized battery bank

Add additional batteries to match loads.

Defective cells

Test and replace battery as necessary.

External

Inspection

Swollen or deformed battery

casing; “rotten-egg” or

sulfurous odor; battery is hot

Thermal runaway

NOTE

: A modest amount of

swelling (or concavity) on

the battery case is normal.

NOTE:

Thermal runaway is a hazardous

condition. Treat the battery with caution.

Allow the battery to cool before approaching.

Disconnect and replace battery as necessary.

Address the conditions that may have led to

thermal runaway (see page 14).

Damaged battery casing

Physical abuse

Replace battery as necessary.

Heat damage or melted

grease at terminals

Loose or dirty cable

connections

Check and clean all connections. Physical

damage on terminals may require the battery

to be replaced. Replace hardware as necessary.

Voltage

testing

Fully-charged battery

displays low voltage

High temperature

Carefully cool the battery. An overheated

battery may contribute to thermal runaway.

Fully-charged battery
displays high voltage

Low temperature

Carefully warm up the battery.

Individual battery charging

voltage will not exceed

13.3 Vdc; high float current;

failure to support load

Shorted cell

Test and replace battery as necessary.

A shorted cell may contribute to thermal

runaway.

Individual battery float

voltage exceeds 14.5 Vdc;
failure to support load

Open cell

Test and replace battery as necessary.
