2. Charger Installation and Operation
This is one of the most powerful battery chargers in the
world. Please observe the warnings & safety precautions
before rushing to install and operate the charger.
Normal Start (Recommended)
1) Clean battery poles for the DC cable and secure the
battery charger in a well ventilated area, make sure
the mounting surface is flat and without soft
covering material or loose paper sheet. Any
ventilation holes must be uncovered.
2) Connect the DC cables to the battery, carefully
noting the polarity of the battery and cables. Ensure
the AC cable is not yet plugged in, and connect the
DC plug to the DC output port and make sure it is
fully pushed in. Double check the battery connection
is well-connected. Connect the thermistor to the
Multiport.
3) The charger will start initialization. If set, turn off the
Autostart feature by holding the pushbutton knob.
4) While the unit is at the “select profile” screen,
connect the AC mains cable to the C20 socket.
5) The unit is ready to be configured and operated
safely.
Battery-less Start
Start from step 1) in the previous procedure and follow the
following steps
2) Connect the AC mains cable to the C20 socket. Press
and hold the pushbutton knob for at least 5 seconds.
3) The unit will startup in batteryless mode and can be
configured normally. Do not attempt to connect a
battery while the unit is operating in this mode, this
can cause damage to the battery and charger.
4) To turn off the unit, unplug the AC cable and start as
per the Normal Start procedure.

Shutdown
1) The charger will enter sleep mode if inactive for 4
hours. The red status LED will flash periodically. Press
the pushbutton knob for 2 seconds to wake the unit.
2) To disconnect the unit, first ensure the unit is not
charging by pressing and holding the pushbutton
knob. Ensure that the green Charging LED is off.
3) Disconnect the AC mains cable and the DC cable in
this order. The unit will turn off.
3. Battery Profile Selection
Incorrect battery charging is the largest
preventable cause of premature battery failure.
Please see the Alchemi website for list of standard
charge algorithms and for more information.
The Alchemi A.I. charge algorithm is divided into
up to 5 phase sequences to put energy into the
battery correctly. Each phase can be terminated
by 1) voltage,2) current, or 3) a fixed duration. Every
phase has a variable timer to prevent “stuck”
phases where the charger does not shutdown.
An example 5-step rapid-charge Lithium profile is
demonstrated below using the Alchemi A.I. charge
algorithm.
