> Donotexposerechargeablebatteriestore,asthereisariskofexplosion!
> KeeprechargeableLiPobatteriesawayfromchildren.Storerechargeablebatteriesin
adry,coolplace.
> Ifarechargeablebatteryisdeformedordamagedduringacrash,itmustnolongerbe
used.Thesameappliesfor“swollen”rechargeablebatteries,orrechargeablebatteries
with other visible deformation or leaks. Do not attempt to charge such rechargeable
batteries!Dangerofreandexplosion!
> Disposeofsuchrechargeablebatteriesinanecologicallysoundfashion.
> The general hazard notices for handling batteries and rechargeable batteries also
applytorechargeableLiPobatteries.
15.5.2.2 Total discharge
> Since discharging below 3.0 V per cell would lead to permanent damage of the
rechargeablebatterypack,thistotaldischargingistobepreventedasfaraspossible.
> Forsafetyreasons,programmablecruisecontrols/ightcontrolsystemsshouldbeset
insuchawaythattheundervoltagedetectionhasalreadyrespondedbeforeavoltage
of3.0Vpercellisreached(e.g.3.2V).Alternatively,opticalundervoltagedisplaysare
also recommended.
15.5.2.3 Correct dimensioning
> Asthecurrentdrawnrises,thebatterypackwarmsandtheusablecapacityislowered.
The ideal operating temperature during discharge is between
+20 and +40 °C and must
notexceed +60 °C evenunderextremeload.
> Themaximumshort-timedischargecurrentisstatedinthetechnicaldatasheetsorcan
bereaddirectlyfromthebatterypack.Thevalue“C”alwaysreferstothecapacityvalue
oftherespectivebatterypack.
Example:
A battery pack with a capacity of 2100 mAh and ”20 C” can be dis-
charged with 2100 mA x 20 = 42 A maximum.
> However,themaximumpermissiblecontinuouscurrentisclearlylower.Ifthereareno
precisemanufacturer’sspecications,thebatterypackshouldnotbedischargedwith
morethanapprox.50%ofthemaximumpermissiblesurgecurrentoveralongterm.
15.6 Miscellaneous
> Consultanexpertwhenindoubtaboutoperation,safetyorconnectionofthedevice.
> Maintenance,modicationsandrepairsaretobeperformedexclusivelybyanexpert
orataqualiedshop.
