Users of equipment that rely on Ni-Cd, NiMH and Li-Ion rechargeable batteries, including Public Safety First Responders, Fire and Law Enforcement, state/local and federal agencies, will now be able to take advantage of second generation Negative Pulse Technology (Software based) Battery Maintenance Solution System units, a concept product created by AdvanceTec Industries Inc. This new generation software based Negative Pulse Technology allows users to monitor in "real time," by means of a color graph, the charging and conditioning process of the battery. Connected to a PC or a Laptop, the program will show on the monitor the different activity phases (Soft ' Full Charging modes/Topping ' Maintenance modes/Discharging mode ' Capacity Analyzing/Charge complete) specifying battery current, battery voltage, charge voltage, phase time and finally charging and conditioning results after the process is done.
