What happens when Ni-MH batteries are used in cold weather?
Since the chemical reactions inside the battery become weaker when the temperatures are extremely low, the batteries will not be able to provide their usual performance. (This is a common characteristic of all batteries.) When using the Ni-MH batteries at temperatures below + 14F (-10C), we recommend charging the batteries for 3-8 minutes to provide the catalyst to activate the chemical process. This will allow the batteries to provide their normal performance levels.
