Please do not point the flashlight directly into people's eyes as this one is very very bright.
Charge the battery before it runs out.
When using for the first time, remove the plastic film from the battery. (Your understanding is greatly appreciated.)
If your flashlights are rarely used, e.g. B. once a month or less, it is recommended to remove the batteries and store them separately. This protects against corrosion and can extend the life of the batteries.
