• Do not expose the battery to temperatures below 0°C (32°F) or above 46°C (115°F). This may adversely affect the battery
pack.
• While the battery may not provide 100% capacity at temperature extremes, its capacity is restored when the battery tem-
perature return to a normal range, around 20°C (68°F).

that the battery LED will indicate that the charge has stopped; However, this does not necessarily mean that your battery
is fully charged.
