Discharging
The main purpose of discharging is to remove the 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 batteries cannot be discharged
to lower than the minimum voltage or it will cause a rapid loss of capacity or total
failure. Generally, Lithium batteries do not need to be discharged. Please pay
attention to the minimum voltage of a Lithium battery to protect the battery life.
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 called “memory effect.” It is
said that NiCd and NiMH batteries suffer from “memory effect.” NiCd has more
“memory effect” than NiMH.
It is recommended that Lithium batteries 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 subject to 10 or more charge cycles. The cyclic process of charge and
discharge will optimize the capacity of the battery pack.
WARNING AND SAFETY NOTES
batteries, in particular, should be charged according to the charging instructions
provided by the manufacturer.
Do not attempt to disassemble the battery pack arbitrarily.
Please note that lithium battery packs can be wired in parallel and in series. In
the parallel connection, the battery’s capacity is calculated by multiplying the
single battery’s capacity by the number of cells when total voltage
stays the same. The voltage’s imbalance may cause a fire or explosion. Lithium
batteries are recommended to charge in series.
