This is the CPU controlled Reverse Pulse Technology Battery Charger from Ultipower.

Reverse pulse charging technology (patented) desulphanates and revives deeply discharged batteries. It will tell you if a battery is recoverable or not. You can see this on the display, on start-up it will go into TEST mode and apply a high charging voltage to the battery, stop and measure the rate of voltage drop. If the rate of drop is excessive it will inform you that the battery is unable to be successfully recovered and will stop charging.
