WARNINGS AND SAFETY NOTES
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.
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. Gen-
erally, 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 partially 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
optimize the capacity of battery pack.
