• To avoid short-circuits between the charge lead, always connect the charge
cable to the unit first and only then to the battery to be charged or discharged.
Reverse the hsequence when disconnecting.
• Do not attempt to disassemble the battery pack arbitrarily. You have to pay
attention to verify the capacity and the voltage of the Lithium battery pack. It may
be composed of parallel and series connection mixed. In parallel link the
capacity of the battery pack is multiplied by the number of cells but the voltage
remains same. That kind of voltage imbalance causes a 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 also have to pay attention on the process 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‘remem-
ber’ 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 selfdischarge during storage. NiMH batteries have less
memory effect than NiCd.
• The Lithium battery prefers a 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.
• The brand-new NiCd battery pack is partially useful with its capacity until it has
beeen subjected to 10 or more charge cycles in any case. The cyclic process of
charge and discharge will lead to optimise the capacity of battery pack.
Those warnings and safety notes are particularly important. Please
follow the instructions for a maximum safety; otherwise the charger and
the battery can be damaged violently. And also it can cause a fire to injure
a human body or to lose the property.
