Универсальный инструмент для ремонта аккумулятора ноутбука/тестер ноутбука тестирование

Suitable for 95% laptop batteries in the market, can test laptop batteries' capacity, voltage, current etc, with charge and discharge function, can connect computer to display details data!!!

Full function of the tester RFNT3:

Charge

Active, pre-charge, constant current and constant voltage are the stages of charging mode. The

initial charging mode depends on the battery voltage, so active and pre-charge don't happen to

every batteries

Discharge  

Constant current discharge for double loads

Test

Testing time is 30 seconds and the purpose is to check both the charging and discharging

 performances

Capacity Correction  

The battery capacity value in the battery management chip will different from the actual capacity

after a battery goes through many recycling cycles. It will affect the use of the battery when the

difference reaches a certain degree. Capacity correction is to deep discharge a battery and then

fully charge, which will correct the capacity value in the battery management chip.

50% Capacity

CD50%: charge firstly, and then discharge to 50% capacity

DC50%: discharge firstly, and then charge to 50% capacity

Online Functions

Tester can be connected with master machine via a USB port. Users can monitor, control and set

parameters via Battery Manager software in the master machine

Monitoring

Battery information can be monitored via three windows

Control

Battery Manager can control slave machine completely. Right-click menu on the battery bar

includes the related commands.

Pre-charge:

Tester goes into pre-charge status when voltage of single cell < 3000mV.

Constant current:

Tester goes into fast charge status when voltage of single cell > 3000mA & < 4200mA. Fast charge current relates to the battery nominal capacity.

At the end of charge:

The current intensity begins to decrease when tester goes into constant voltage charge status. It stops charging when the capacity reaches 100% and the current intensity less than 1A or the current intensity reduce to the end charge current.

Charging current

There is a connection between current intensity and charge mode. The details as below:

The max charge current is 2.5A.

Nominal capacity Pre-charge current Fast charge current End charge current

≥6000                400mA            2500mA              300mA

≥3500                400mA            2000mA              200mA

Else                  200mA            1000mA              100mA
