A: Charging the battery before the power runs out completely is suggested. It is best to charge when the remaining power is about 5-10%, and the battery should be charged in a relatively dry place.

A: The ideal preservation method is to charge the battery to about 40% and then put it in a cool and dry place. About 68 degrees Fahrenheit is the ideal preservation temperature.
