Charging

During charge process, a specific quantity of electrical energy is fed into the battery. The
charge quantity is calculated by multiplying charge current by charge time. The maximum
permissible charge current varies depending on the battery type or its performance, and
can be found in the information by the battery manufacturer. Only batteries that are
expressly stated to be capable of quick-charge are allowed to be charged at rates higher
than the standard charge current.

Connect the battery to the terminal of the charger: red is positive and black is negative.
Due to the difference between resistance of cable and connector, the charger can not
detect resistance of the battery pack, the essential requirement for the charger to work
properly is that the charge lead should be of adequate conductor cross-section, and high
quality connectors which are normally gold-plated should be fitted to both ends.

Always refer to the manual by the battery manufacturer pertaining to charging methods.
Operate according to their recommended charging current and charging time. lithium
batteries, in particular, should be charged strictly according to the manufacturer’s
instruction.

Close attention should be paid to the connection of lithium batteries.

Do not attempt to disassemble the battery pack arbitrarily.

Please get highlighted that lithium battery packs can be wired in parallel and in series. In
the parallel connection, the battery's capacity is calculated by multiplying single the
battery's capacity by the number of cells, bearing in mind that total voltage stays the
same. If the voltage is imbalanced, it may cause a fire or explosion. Lithium batteries are
recommended to charge in series.

Discharging

The main purpose of discharging is to clean the residual capacity of the battery, or to
reduce the battery' voltage to a defined level. The same attention should be paid to the
discharging process as the charging process. The final discharge voltage should be set up
correctly to avoid deep discharging. Lithium batteries cannot be discharged to lower than
the minimum voltage, or it will cause a rapid loss of capacity or a total failure. Generally,
lithium batteries don't need to be discharged. Please pay attention to the minimum voltage
of lithium batteries to protect them.

Some rechargeable batteries have a memory effect. If they are partly used and recharged
before the whole charge is accomplished, they remember this and will only use that part of
their capacity next time. This is a 'memory effect' It is said that NiMH and NiCd batteries
are suffering from memory effect. NiCd has more ‘memory effect’ than NiMH.

Lithium batteries are recommended to be discharged partially rather than fully. Frequent
full discharging should be avoided if possible. Instead, charge the battery more often or
use a battery of larger capacity. Full capacity cannot be reached until it has been
subjected to 10 or more charge cycles. The cyclic process of charge and discharge will
optimize the capacity of battery pack.
