Good Battery tester
I like this variable constant electronic load. It is an all in one unit. It really does not test anything from 1.5 VDC or less. However, it is great when testing 2 or more batteries 1.2 V and 1.5 V cells
I have had the unit for a number of months, and have made the unfortunate error of reversing the voltages, which I am not sure that may have also impacted the heat sensing circuitry. The fan must be in operation for this unit to work properly. With too much of a current load the unit will shut down dramatically, turns off.
This unit needs 9 VDC to operate. I did my own supply to the onboard fan.
I have like this little marvel, and may even purchase another one.

Easy to use, accurate
This is the simplest battery current tester I have used. It only does one thing - provide a constant current load for testing the capacity of various cell/battery types: NiMh, Nicad, etc. I have used it with a 18V 2.2 AH Dewalt Nicad, and a couple of AA size cells. It will not test fewer than 2 cells as the minimum low voltage set point is 1.5V.
The voltage and current display on this unit compared within 1% of a Fluke DVM.
The device current load was not given in the data sheet. Using a 9VDC supply the idle current was about 40mA, and went to 140mA with the fan on.
