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 cannot 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 battery manufacturer about charging methods,
recommended charging current and charging time. Especially, the lithium
battery should be charged according the charging instruction provided by the
manufacturer strictly.
Attention should be paid to the connection of lithium battery especially. 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
battery capacity by the number of cells with total voltage stay the same. The
voltages imbalance may cause fire or explosion .Lithium battery is recommended
to charge in Series.
Discharging
The main purpose of discharging is to clean 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 charging. The final discharge voltage should be set
up correctly to avoid deep-discharging. Lithium battery cannot be discharged to
lower than the minimum voltage, or it will cause a rapid loss of capacity or a total
failure.
Generally, lithium battery doesn’t need to be discharged. Please pay attention to
the minimum voltage of lithium battery to protect them.
Lithium batteries are recommended to be discharged partially rather than fully.
Frequent full discharging should be avoided if possible.
