Safe use of the battery

The  battery  may  be  charged  with  USB  port  in  the  computer  or  laptop.
Nevertheless, it is not a recommended form of charging an operating device due
to  the  low  charging  current  offered  by  the  USB  -  even  though  the  device  is
connected  to  a  power  source  battery  can  still  get  discharged.  If  you  wish  to
charge your device this way turn off the device. If the battery level is low, recharge
it to continue the use of the device. If you wish to prolong the battery life span,
discharge the battery beneath 20% of the battery capacity and charge it back to
100%. If not used, unplug the charger from the device. Excessive charging might
cause shortened battery life. The temperature of the battery has an impact on
its  charging  cycle.  Prior  to  the  charging  process,  cool  the  battery  or  raise  its
temperature  so  that  it  is  similar  to  the  room  temperature.  If  the  battery
temperature  exceeds  40°C  the  battery  must  not  be  charged!  Do  not  use
a damaged battery! The battery life span can be shortened, if it has been exposed
to very low or very high temperatures - this causes interference to the device,
even when the battery has been properly charged.
