Do not attempt to disassemble the battery pack arbitrarily.
Ÿ
You have to pay attention to verify the capacity and the voltage of the
Ÿ
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 recom-
mend you compose the Lithium battery pack in series only.
Discharge
The typical purpose of discharge is to determine the residual capacity of the
Ÿ
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 menory effect. If they are
Ÿ
partly usedand recharged before the whole charge is drawn out, they
‚remember' this and next time will only use that part of their capacity.
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 prefers a partial rather than a full discharge. Frequent
Ÿ
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
Ÿ
has been 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 c an cause a fire to injure a human
body or to lose the property.
