WARNING AND SAFETY NOTES
!
Discharging
10
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.
The main purpose of discharging is to clean residual capacity of the battery, or to reduce the
battery’s 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 reached 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.
