Warning & Safety Notes
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 manufac-
turer. 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 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 par-
tially 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 op-
timize the capacity of battery pack.
