200.4 Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries
Lead-Calcium cells are the most common type of battery used today in standby equipment. By design
it is as maintenance free as a battery can be. It is recommended, however, that some simple steps be
taken to increase system life and maximize reliability:
A) A quarterly visual check of the batteries should be conducted to look for deformities in the
cases and terminal corrosion. Any defective batteries should be replaced. All corroded ter-
minals, regardless how slight, are to be cleaned and retightened at once to prevent failure
of the entire battery bank.
B) Once a year, all battery connections should be checked for tightness and re-tightened if
necessary.
200.5 Battery Replacement Procedure
WARNING:
Always use the same quantity and type of battery as replacements.
Substituting batteries not supplied by the Manufacturer will void the UL listing of the system and may
cause equipment failure. To ensure the superior performance of your
VST
inverter system and to
maintain proper charger operation, replace spent batteries only with cells having the same part num-
ber, voltage and ampere-hour rating as the original batteries.
1.
Follow the proper shut down procedure as described in
Section 200.1
.
2.
Disconnect the battery string beginning with the white inter-cell connectors followed by the red
(B+) and black (B-) connectors.
3.
Remove the batteries from the cabinet.
4.
Install new batteries following the instructions outlined in
Section 106.2
.
200.6 Battery Disposal
WARNINGS:
• Do not dispose of batteries in a fire, the batteries could explode.
• Do not open or mutilate batteries.
• Released electrolyte is highly toxic and harmful to the skin and eyes.
CAUTION: Batteries contain lead. Many state and local governments have regulations
about used battery disposal. Please dispose of the batteries properly.
