Phase
4 [4112] 4=trickle charge until fully charged (battery was
unable to generate a capacity of 5% with fast-charge);
1=discharge; 12=proceed back to phase 2.
Exit Phase
[09] O=no cycle; 1=done, trickle charge.
Self-discharge test
After the battery has aged or has performed over 1000
charge-discharge
cycles, the self-discharge of the
rechargeable battery increases. Typically, a NiCd
battery loses 10% of the original capacity over a 24-
hour storage period. At higher storage temperatures,
the self-discharge is higher.
When performing the self-discharge test, we compare
the battery capacity reading that was obtained right
after charge and compare it with the reading that is
taken after the user-selected rest period. A practical rest
period may be 12 or 24 hours.

Program
The battery is first charged, then discharged to measure
the full capacity. The battery is then recharged and put
on a rest period. After that time, the battery is
discharged to measure the remaining capacity. The
comparison between the second last reading (Full
Capacity) and the last reading (capacity after rest)
reveals how much capacity was lost due to self-
discharge.
