Refreshing (Charge Refresh); Testing (Charge Test); Quick Testing (Quick Test) - VOLTCRAFT P9-4 Notice D'emploi

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 significantly 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.
