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, 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’s capacity by the number of cells with total voltage
stay the same. The voltage’s 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 can not 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 the battery.
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 NiCd and NiMH batteries are suffering from memory effect. NiCd has
more memory effect than NiMH.
Lithium batteries are recommended to be discharged partially rather than fully
discharged. 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 used 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.
