3) Recommendations to batteries
The power of a battery is maximal with normal room temperature, i.e 20° Celsius (68° F).
And it drops with decreasing temperatures more and more.
With approx. -20° Celsius (-4° F) discharging of a block battery comes to the end.
Therefore, it also delivers no more electricity.
Batteries should be stored long-term with low temperature, i.e. 10° Celsius (50° F).
To deliver maximal power, battery must have normal room temperature (see above)
Caution:
Never warm batteries on direct heat sources like radiators etc.!
Batteries, stored below 0° Celsius (below 62° F), which were warmed up on normal room temperature, cannot be stored afterwards in the cold again!
To get maximal power, keep all contacts clean and check whether they firmly touch.
