We present our innovative product, which will be useful at any car service station, and for those who want to work with electrified vehicles, it is a must-have – the MS800 battery tester for hybrid and electric vehicles from MSG Equipment!

So in the video, we showed how to work with the tester on the example of a nickel-metal hydride battery from the 2012 Toyota Prius and a lithium-ion battery from the Hyundai Tucson Hybrid.

And you can see:
– how the tester works;
– with what types of batteries;
– how to diagnose batteries correctly;
– and much more.

We offer free technical support and a two-year warranty with our equipments.

And, of course, we have a training course on MS800. There, we explain in detail the features of the batteries, their differences, safety precautions when working with them, and many other details. You can register here:

Finally, we would like to highlight the features of our tester.
So the MS800:
– Diagnoses high-voltage battery modules to determine their capacity.
– Charges series-connected battery cells that have become unbalanced over time.
– Prepares batteries for installation in the vehicle by balancing the voltage of all modules.
– Prepares the modules for storage by charging them to a certain level.
– The tester has 36 independent channels for testing (balancing) Ni-Mh or Li-Ion modules;
– Automatic mode of operation;
– Protection of battery modules from: overcharging/overdischarging; overheating; incorrect connection (reverse polarity).
– Saving of diagnostic results and convenience in viewing and analyzing diagnostic results.
