Storage and safety notice
Although charged Lithium-Ion batteries may be left unused for several months, their
capacity may be depleted due to build up of internal resistance. If this happens they
will require recharging prior to use. Lithium-Ion batteries may be stored at tempera-
tures between-20°C to 60°C, however they may be depleted more rapidly at the high
end of this range. It is recommended to store batteries within normal room tempera-
ture ranges.
