  Make sure the battery is fully 
charged before use.
  Clean the battery and terminals with 
a clean, soft, dry cloth.
  The battery may be warm during use 
or recharging. This is normal.
  When storing the battery for an extended 
period, be sure that it is not completely 
charged, nor completely discharged. 
The ideal level is a 40% charge. This is 
approximate; the closer the battery is to 
this level, the better it will hold its charge 
during storage. The battery should be stored 
in a cool, dry place. The recommended 
temperature for storage is 59°F (15°C). You 
may store a battery in a refrigerator. Do not 
store batteries in a freezer.
  Remove the battery from your equipment 
when not in use. Some electronic equipment 
will draw current even when the switch is off.
  When operation time has noticeably 
shortened, the battery may need to be 
replaced.
