Charging Consideration
It is important to consider the surrounding temperature whenever you are charging the Li-Ion battery pack.
The process is the most efficient in the normal room temperature or slightly cooler. It is essential for you to
charge battery within the stated range of 32°F to 113°F (0°C to 45°C). Charging battery outside of the
specified range could damage batteries and shorten its life cycle.
Effects of Overcharging Batteries
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 a long period of time or always using the cradle to charge the
batteries of terminal. The cradle starts the charge process in the quick charge 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).
