Product Description

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!!!


1. Full function of the tester RFNT3:



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



Constant current discharge for double loaders.



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



-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



Battery information can be monitored via three windows.



Battery Manager can control machine completely. Right-click menu on the battery bar includes the related commands.



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
