Discharging
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 deepdischarged, set the final discharge voltage correctly. Lithium
batteries should not be deepdischarged 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 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.
