CAUTION:
A battery can present a risk of electrical shock and high short circuit current. Battery replacement should only
beperformedbyqualiedservicepersonnelfamiliarwithbatterysystems.Allsafetyprecautionsoutlinedatthe
beginning of this section must be observed when servicing, maintaining or replacing batteries
Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries (Includes Type S and Type G 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. Coupled with the diagnostic and self-testing capabilities of the LSN system,
these batteries provide one of the most reliable and carefree inverter systems available today. It is recommended,
however,thatsomesimplestepsbetakentoincreasesystemlifeandmaximizereliability:
• Ifsystemisinstalledinaremoteareawherethesystem'salarmsmaynotbeheard,itisrecommendedthatthe
system be checked weekly for alarm conditions,
• 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 terminals, regardless how slight, are to be
cleaned and retightened at once to prevent failure of the entire battery bank.
• Onceayear,allbatteryconnectionsshouldbecheckedfortightnessandre-torquedifnecessary.Torque
specicationscanbefoundonthebatterylabel.
Nickel-Cadmium Batteries
Used in harsher environments, the wet nickel cadmium battery is designed for a 25-year life. When properly
maintaineditwillgiveyearsofreliableperformance.Caremusttobetakentomaintainadequateelectrolytelevels
andterminalcleanliness.Useonlydistilledwaterwhennecessary.Neveruseanykindofacidtorellthebattery,
seriousdamageandinjurymayoccur.
Thesamefrequencyandproceduresaslistedaboveforthelead-calciumbatteriesshouldbefollowed.
Ifyouhaveanyquestions,contactDualLite'sTechnicalSupportCenterat1-800-848-6439.
Please dispose of all batteries properly.
Battery Replacement Procedure
WARNING: Always use the same quantity and type of battery as replacements.
SubstitutingbatteriesnotsuppliedbyDual-LitewillvoidtheULlistingofthesystemandmaycauseequipmentfailure.
To ensure the superior performance of your LSN inverter system and to maintain proper charger operation, replace
spent batteries only with Dual-Lite cells having the same part number, voltage and ampere-hour rating as the original
batteries.
1. Follow the proper shut down procedure as described in Section 300.1.
2. Remove battery cabinet fuses and test them for continuity. Faulty fuses will prevent batteries from charging and
render the battery bank useless during a power outage.
3. Break down the battery bank beginning with the intercell connectors. These cables tie the batteries installed on
the same shelf together.
4. Next remove the inter-tier cables. These cables connect the batteries located on different shelves together.
