How to Prolong the Battery Life 
Battery Use:
1. For the most effective battery use, it is recommended that you wait until the battery 
    is completely drained before recharging it.  This way, you can get the longest life and a
    complete current supply from your battery.
2. New batteries must go through a few cycles of being completely charged and drained
    before getting the maximum results.  In other words, the battery should be allowed to
    experience the full range between maximum and minimum voltage.
3. The first time you charge the battery, you should charge it 100%.  It must be charged 3-4
    hours. 
   
Battery Hot Swap
In order to ensure that your current data is safely stored, we remind you that you must 
follow the steps below when changing the battery.
1.  Unplug all external devices.
2.  Set the system on Standby.
3.  Remove the battery.
4.  Replace it with a fully charged battery.
5.  Press the On/Off button and restore the system to operating mode.
     The above procedure is the quick-change battery hot swap and should be completed
     in under five minutes (otherwise, data may be lost).
1. Touching either end of the battery with anything metallic can result in a short circuit.
2. Do not hit the battery, put it anywhere warm, or let it get wet or fall.
3. Charging the battery for too long can shorten its life.  Please do not charge it for
    more than 24 hours.
