Plug in and switch on the charger after it is connected to the battery.

This is another OEM tester for batteries. This charger is a $3000+ device that not only tests batteries, it also has the ability to recondition and charges the battery automatically. When charging batteries, they should be charged on a waveform, never a constant charge. Of course this is very expensive technology and therefore most chargers you will see available for sale only charge at a constant rate. FYI – We currently are waiting for the newest version of this, the GRX-3000!
