c) Refreshing (CHARGE REFRESH)

• The rechargeable battery is charged and discharged 3 times to optimize its performance.

• Usethis programto restore old rechargeablebatteries and rechargeablebatteries which

have not been used for a long time to their original capacity.

• Dependingonthesetchargingcurrentandtherechargeablebattery,thisprocesscantake

between 10 hours and several days.

• Afterthedischargeprocess,theentiredischargedcapacityin"mAh"isdisplayed.

• Duringthechargingprocess,the“mAh”displayedreferstothechargedcapacityreached

following the previous discharge process.

d) Testing (CHARGE TEST)

• This program checks the current capacity of the rechargeable battery.

• The maximum capacity is determined by discharging the rechargeable battery after it has

been fully charged.

• Ifthemaximumcapacityissignicantlybelowthenominalcapacity,therechargeablebattery

has nearly reached the end of its service life.

e) Quick testing (QUICK TEST)

• This program analyses the dynamic internal resistance of the battery.

• Within10seconds,therechargeablebatteryresistanceappearsinmilliohm.

• The internal resistance of fully functioning rechargeable batteries is between approx. 100 -

300 milliohm.

• Iftheinternalresistanceisabove1000milliohm,therechargeablebatteryinquestioncan

nolongersupplyahighcurrentsuchasisneededforoperatingamultimeter,forexample.

• Inthecaseoffullydischargedrechargeablebatteries,itisnotpossibletodetermineacorrect

result.

• The measured value is strongly dependent on the quality of the contacts. If you test the same

rechargeablebatteryagain,adeviationof10-20%mayoccur.Thisisnormalandisnota

malfunction.

 Assoonastherechargeablebatteryhasbeenfullychargedtotheendofaprogram,

the display shows the indicator “FuLL”. The device automatically switches to trickle

charging (only with NiMH and NiCd rechargeable batteries). The trickle charge

ensures protection against overloading and compensates for self-discharge.
