• To avoid short-circuit between the charge leads, always connect the charge cable to
the unit first and only then to the battery. Reverse this sequence when disconnecting.
Short-circuiting either the battery or charger can cause permanent damage.
• It is important to verify the capacity and the voltage of the Lithium battery pack. It
may be composed of parallel and series connection of cells. For parallel connection
the capacity of the battery pack is multiplied by the number of cells but the voltage
remains same. A voltage imbalance between cells caused by mixed connection of
cells can cause fire or explosion during charge process. We recommend you compose
the Lithium battery pack in series only.
DISCHARGE
• The typical purpose of discharge is to determine the residual capacity of the battery, or
to lower the voltage of battery to a defined level. When you discharge the battery you
must pay attention to the process the same as charging. To avoid the battery becoming
deep-discharged, set the final discharge voltage correctly. Lithium batteries should not
be deep-discharged to lower than the minimum voltage, as this leads to a rapid loss
of capacity or a total failure. Generally, you do not need to discharge Lithium battery
voluntarily.
• Some rechargeable batteries are said to have a memory effect. If they are partly used
and recharged before the whole charge is drawn out, they ‘remember’ this and next
time will only use that part of their capacity. This is a ‘memory effect’. NiCd and NiMH
batteries are said to suffer from memory effect; they prefer complete cycles. Fully
charge then use until empty, do not recharge before storage - allow them to self-
discharge during storage, NiMH batteries have less memory effect than NiCd.
• The Lithium battery prefer partial rather than a full discharge. Frequent full discharges
should be avoided if possible. Instead, charge the battery more often or use a larger
battery.
• A brand-new NiCd battery pack only uses part of its capacity until it has been
subjected to 10 or more charge cycles. The cyclic process of charge and discharge
will lead to optimised capacity of your battery pack.
These warnings and safety notes are extremely important.
Please follow instructions for maximum safety; otherwise the
charger and the battery can be damaged permanently. Improper
use may cause fires and injury to yourself and your property.
