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 the discharge process is being
used, the procedure must be monitored for the duration of the process. In order to avoid
the battery becoming deep-discharged, set the final discharge voltage correctly. Lithium
batteries should not be deep-discharged, so please set the final discharge voltage
manually. If this is not done, it will lead to a rapid loss of capacity or a total failure.
Generally, you do not need to discharge Lithium batteries 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, the battery will 'remember' this
and the next time the battery is charged it will only use that part of it’s 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.
Lithium batteries prefer a partial discharge rather than a full discharge. Frequent full
discharges should be avoided if possible. Instead, please charge the battery more often
or use a larger battery.
A brand-new NiCd battery pack is partially useful with its capacity until it has been
subjected to 10 or more charge cycles. The cyclic process of charge and discharge will
optimise the capacity of battery pack.
These warnings and safety notes are very important.
Please follow the instructions
accurately for maximum safety. If these safety notes are not adhered to, the battery can
be severely damaged. There is also a risk of combustion and fire when the charger is
not used responsibly.
