ATTENTION!
This product contains a rechargeable Lithium-ion battery pack. Lithium-ion batteries
have a much longer life and a higher capacity compared to regular NiCad batteries.
However, care must be taken when storing and using Lithium-ion batteries and all
products containing Lithium-ion batteries. For prolonged storage periods, a
temperature of around 25°C or below 80°F is recommended. In addition, the batteries
should be stored at a charged level of around
60%
of capacity. Always keep battery
and drill controller away from wet and/or heated surfaces.
Over-discharging Lithium-ion batteries will result in permanent battery damage.
If you need to stock Pro-40K units for a prolonged period of time, we
recommend that the Pro-40K controller be charged at least once every 6
months to prevent permanent damage to the Lithium-ion battery pack.
