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 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.
