5. Discharging
During discharge, the voltage of a charged Li-on cell will steadily drop from an
initial 4.2V once loaded. It is for this reason that a voltage sensing protection
circuit is fitted to prevent over discharge of any one cell.
6. Storage
When the battery is not in use unplug the seven wire plug from the main
Guardian Board.
The battery should be kept in storage in a clean, dry and ventilated area; it
should be avoided to touch with any corrosive substance and should be away
from excessive heat and open flames.
Storage of cells between 32°F and 85°F is recommended although short periods
of storage (<24Hrs) at temperatures up to +85°F will not cause any long term
negative effects. Where possible, cells should be stored in an open circuit
condition in a dry environment close to room temperature. Li-on cells exhibit
excellent charge retention over a wide temperature range. When stored at room
temperature, a fully charged cell will only loose around 5% of its original capacity
in the first month and this loss will drop to around 3% for subsequent months.
7. Battery Cycle
When charged and discharged cycles degrade the capacity of the battery.
