1. Introduction
This charger is designed for charging a variety of 12V lead acid
batteries widely used in cars, motorbikes and some other vehicles;
such as WET, GEL, AGM and so on, with a capacity ranging from
1.2Ah to 120 Ah. The specialized design of the device, called “the
three stages charging strategy”, allows the battery to be recharged to
almost 100% capacity, and makes it possible to leave the battery
connected to the charger when not in use, to keep it always in perfect
state without damaging it. Three charging modes are available for
charging different batteries under different ambient temperatures,
which lets the user select best one to charge the battery more
efficiently and safely. Compared with a normal battery charger, this
device offers a special function of rescuing apparently dead batteries,
by which deep discharged batteries can be charged. Full protection
against reverse polarity connection and short circuit ensures safest
charging operation. By the electronic switch embedded inside, the
charger won’t act immediately when a battery connected to it until
either of the charging modes is selected. Sparking, often appearing at
connecting to a battery, is avoided as a result. Furthermore, this
device is controlled by a microcontroller, that makes it smarter and
more reliable. With a protection level of IP65 it can operate safely
even in dusty and humid environment.
