What is memory effect
This effect exists in NiCad batteries and lesser extend in NiMH batteries and also known as "lazy battery effect"
It means if a battery repeatedly charged after it has been partially discharged the battery forgets that it has the capacity to discharge all the way, resulting in loss of capacity beyond 25% discharge point
In simpler terms, if u regularly fully charge the battery and then only use 50 %of its capacity before the next recharge eventually be battery will forget about the next 50%
How to avoid
Is to fully charge and then fully discharge the battery at least once a month
How to fix the problem
Modern lithium batteries work differently do not have memory effect

How to avoid

How to fix the problem
- Discharge the battery to 1volt per cell and then fully recharge the battery
- Repeat several times until capacity improves or regain original capacity
