Did you select the appropriate program suitable for the type of battery you are charging?
Did you set up adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired in parallel and in
series, i.e. a 2 cell pack can be 3.7V (in parallel) or 7.4V (in series).
Have you checked that all connections are firm and secure?
Make sure there are no intermittent contacts at any point in the circuit.
Batteries installed in a device or which are electrically linked to other components.
Batteries that are not expressly stated by the manufacturer to be suitable for the currents the
charger delivers during the charge process.
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.
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 quickcharge 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 goldplated 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.
