Battery
When batteries are stored over a year, battery cell manufacturers advise that some irreversible deterioration in
overall battery quality may occur. To minimize this loss, they recommend storing batteries half charged in a dry,
cool place between 41° and 77°F (5° and 25°C), the cooler the better, and removed from the equipment to prevent
the loss of capacity. Batteries should be charged to half capacity at least once a year. In order to charge a battery
to half capacity, take a fully discharged battery and charge it for 2 hours. If an electrolyte leakage is observed, avoid
any contact with the affected area and properly dispose of the battery.
Cradles
•
Although the cradles are water and dust resistant, do not expose them to rain or moisture for an extended
period of time. In general, treat the cradles as you would a pocket calculator or other electronic instrument.
•
Do not drop the cradles or subject them to strong impact.
•
Protect the cradles from temperature extremes. Do not leave them in a car on a hot day, and keep them
away from heat sources.
•
Do not store or use the cradles in any location that is extremely dusty, damp, or wet.
•
Use a soft cloth dampened with a 50/50 solution of isopropyl alcohol and water.
• Do not allow the solution to form a pool of liquid anywhere in the cradle.
• Do not use a large amount of solution to cause the cradles to remain wet.
