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.
A battery pack which consists of different types of cells (including
different manufacturers)
A battery that is already fully charged or just slightly discharged.
Non-rechargeable batteries (Explosion hazard).
Batteries that require a different charge technique from NiCd,
NiMh, LiPo or Gel cell (Pb, Lead acid).
A faulty or damaged battery.
A battery fitted with an integral charge circuit or a protection 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.
Please bear in mind the following points before
commencing charging:
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.
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 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 voltage s
imbalance may cause fire or explosion .Lithium battery is
recommended to charge in series.
Never attempt to charge or discharge the following types
of batteries.
