Overcharging may occur when a Li-Ion rechargeable battery is charged in regular or quick charging rate
after it has been fully charged, but there is no risk of overcharging while charged in trickle charging rate.
A battery left to charge for several weeks may appear to have minimal capacity. This type of failure can be
remedied by temporarily depleting the battery of its power and recharging it to rejuvenate it. This condition
can be prevented by avoiding overcharging for long period of time or always using PT063D to charge the
batteries of terminal. The PT063D starts the charging process in quick charging rate and switches to trickle
charging rate when it detects the battery is fully charged.
2.5 Storage and Safety Precautions
Batteries should be stored in an open environment condition and placed where there is no risk of
accidental shorting or other damage. Although charged Li-Ion batteries may be left unused for several
months, their capacity may be reduced due to back up and internal resistance. If this happens, they will
require recharging prior to use. Li-Ion batteries may be stored at temperatures between -4
°
F and 158
°
F
(-20
°
C to 70
°
C).
