Batterypacksdorequireroutinemaintenanceandcaretomaximizetheirusefullifeand
maintainwarrantycoverage.Readandfollowtheguidelinesinthismanualtosafelyuse

Lithium-Ion Battery Maintenance Guidelines
Accordingtoleadingcellmanufacturers(LG,Samsung,Panasonic),theestimatedlifeofa
lithium-ionbatteryis500chargecycles.Whenstatingapproximateusefullifeofabattery
inunitsof“chargecycles,”cellmanufacturersdenethisasthepointwherethebattery
capacity(Ah)isreducedto80%oforiginal.Thismeansbatteryisnot“dead”after500
chargecycles,butruntimeissignicantlyreduced,andreplacementshouldbeconsidered.
Partialdischargeoflithium-ionbatteriesisne.Thereisno“memoryeect”andthebattery
doesnotneedperiodicfulldischargecyclestoprolonglife.
Overview
Storage
Whenstoring,removebatterypacksfromfanandstoreinadryandcoollocation.Avoid
extremetemperatures.
• RecommendedStorageTemperature:5
o
C to 20
o
C(41
o
Fto68
o
F)
• Maximumrelativehumidityduringstorage:90%RH
NOTE:allbatteriesself-dischargeduringstorage.Highertemperature(>20
o
C or 68
o
F)reduce
thebatterystoragelife.
Lithium-ionbatteriesshouldbestoredinachargedstate,ideallyaround30%stateof
charge(SoC).See“Storage/TransportMode”sectionofthismanualforeasydischarging
stepstofollowbeforestoringbatterypacks.
Long-term(>6months)storageofbatterypacksisnotrecommended.Whenabatterypack
hasbeenunusedfor6months,checkthechargestatusandeitherchargeordisposeofthe
batteryasappropriate.
Recommendations
• Batterypackswilllastsignicantlylongerwhenruninpairs(twobatterypacksperfan)
asthereis50%lessdischargecurrentperpack.
• Aswithanyequipment,batterieswillwearoutfasterwithheavyuse.Depthof
Discharge(DoD)determinesthecyclecountofthebattery.Thesmallerthedischarge
(lowDoD),thelessstressisenactedonthechemistryofthebatteryandthelongerthe
batterywillultimatelylast.Ideally,operatorsshouldavoidfulldischargesandcharge
thebatteryaftereveryuse.
Maintenance and Disposal
• DONOTdisassembletheventilatorformaintenancereasons.
• DonotloosenscrewsoncontrolboxwithoutcontactingEuramcocustomerservice.
Theyaretorquedtoasettingtoachievewatertightness.
• Completelyunravelpowercordandplaceunitonaat,stablesurface.Cleanventilator
periodicallytoremoveaccumulateddustorparticlesfromventilatorguards,impeller
bladeandheatsinkinrearofcontroller(ribbed).Useonlybiodegradabledetergents.If
powerwashing,avoidcontrollerhousingespeciallygasketsandcontrolpanel.
• Contactfactoryforreplacementpartsandinstallationinstructions.Toorderspare
partscallEuramcoGroup+1.619.670.9590 or theteam@euramco.com
• Alwaysdisposeofyourbatterypackaccordingtofederal,stateandlocalregulations.
• Evendischargedbatteriescontainsomeenergy.Beforedisposingof,useelectricaltape
tocovertheterminalstopreventthebatterypackfromshortcircuit.
• Properlydisposeofbatterypackswhennecessary.Contactyourlocalhazardous
materialse-wastecollectiondepartmentfordetailsorproperdisposalofrechargeable
batteries.
