2. OVERVIEW
2.1 About PITE 3932T
PITE 3932T is a compact unit for daily maintenance of single cell, especially for old cells.
It plays three roles: charger, discharger and activator, which will facilitate your
maintenance for batteries. These three functions could be used individually or
comprehensively. When used comprehensively, lag-out battery will experience low-volt
constant current charging and discharging singly or in multi-circles (1~99). By activating
the disabled active material on battery electrode plate, it amends the battery malfunction
caused by chemical failure and thus boosts the capacity of old battery. Activation curve
and certain parameters (e.g.: voltage and resistance) will display on screen as activation
ends.
Battery activation is very significant for resources utilization and efficiency increasing.
However, it is important to know that not all weak batteries could be activated by PITE
3932T. It can only amend the weak batteries whose bad condition is caused by chemical
malfunction instead of physical failure such as short-circuit of electrode plate.
