Warning and Safety Notes Warning and Safety Notes
Have you selected the appropriate program for the battery type you are
charging?
Have you set up adequate current for charging or discharging?
Have you checked the battery voltage? Please note that Lithium battery
packs can be wired in parallel or in series, i.e. a 2 cell pack can be 3.7V
(in parallel) or 7.4V (in series)
Have you checked that all connections are firm and secure?
Make sure there are no intermittent contacts at any point in the circuit.
Charging
During charge process, a specific quantity of electrical energy will be fed
into the battery, which is calculated by multiplying charge current. The
maximum permissible charge current differs on different types of battery
and its performance, which can also be found in the information by the
battery manufacturer. Only batteries to be capable of quick-charge are
allowed to be charged at higher rates than the standard charge current.
Connect the battery to the charger terminal, red is positive while black is
negative. Due to the different resistance between cable and connector,
the charger can not detect the battery pack's resistance. To work
properly for a charger, it's essential for its charge lead to be of adequate
conductor cross-section, and high quality gold-plated connectors must
be fitted to both ends.
Please always refer to the manual by battery manufacturer about
recommended ways of charging, charging current and time, especially
for a Lithium battery, which must be charged according to the instruction
strictly.
Special attention must be paid to the Lithium battery connection.
Never attempt to disassemble the battery pack arbitrarily.
Always remember: Lithium battery can be wired in parallel or in series.
In parallel connection, the battery capacity is calculated by multiplying
each individual battery cell capacity with total voltage staying the same.
Voltage imbalance may cause fire or explosion. Lithium battery is highly
recommended to charge in series.
Discharging
The main purpose of discharging is to clean residual battery capacity, or
to discharge the battery to a defined level of voltage. Final discharge
voltage must be set correctly to avoid over-discharging. Lithium battery
can not be discharged to be lower than its required minimum voltage, or
it will cause a rapid loss of capacity or a total failure. Please pay
attention to the minimum voltage of Lithium battery to protect it.
Some rechargeable batteries have memory effect. If they are partly used
and recharged before whole charging is accomplished, they will
remember this and only use that part of capacity next time. Above is
called memory effect. It is said that both NiMH and NiCd batteries suffer
from memory effect, NiCd, however, suffers more.
