Special Functions - PowerTech MB3912 Instruction Manual

SPECIAL FUNCTIONS:

0V battery charging.
This feature is used for zero volt batteries; it uses a very small pulse current
to sense the connection of the battery. This function is used in lithium
batteries, as lithium battery pack has Protection Circuit Modules (PCM),the
battery pack output is 0V when the PCM have actioned.
Overheating protection
If the appliance becomes too hot during charging, the power output is
automatically reduced. This protects the appliance from damage.
Trickle charging
Once the battery has been fully charged, the charger automatically changes
to trickle charging. Depending on the measured voltage, the charging is
interrupted or the battery is maintained in a fully charged condition with low
voltage currents (1.3A or 0.9A / 0.08A).
NOTE: a battery can remain permanently connected to the charger without
damage or adverse effect on its performance. The trickle charge can be used
to maintain a battery.
