Battery Notice 
 
1.  To guarantee optimal performance, it is recommended that rechargeable 
batteries be replaced every year, or after 500 charging cycles are 
completed. It is normal for the battery to balloon or expand after one 
year or 500 cycles. Although it does not cause damage, it cannot be 
used again and must be disposed of according to the location's safe 
battery disposal procedures. 
2.  If a battery performance decreases more than 20%, the battery is at the 
end of its life cycle. Stop use and ensure the battery is disposed of 
properly. 
3.  The length of time that a battery lasts depends on the battery type and 
how the device is used. Conserve the battery life by doing the following: 
  Avoid fully uncharging the battery because this places additional 
strain on it. Several partial uncharges with frequent charges are better 
than a fully uncharged battery. Charging a partially charged battery 
does not cause harm to the unit. 
  Keep the battery cool. Avoid hot vehicles. For prolonged               
storage, keep the battery at a 40% charge level. 
  Do not leave the battery uncharged and unused for an extended 
period of time, the battery will wear out and the longevity of the 
battery will be at least half of one with frequent charges. 
4.  Protect battery life by not over or under charging the battery. 
5.  Please do not leave battery unused for long time without charging it. 
Despite unitech’s safety precautions, the battery pack may begin to 
change shape. If so, stop using it immediately. Please check to see if 
you are using a proper power adapter to charge the battery or contact 
your service provider for service. 
6.  If you cannot charge the battery after it has been idle for an extended 
period of time and it begins to heat up, please do not try to charge it. It 
may not be functional anymore. 
7.  Please only use the original battery from unitech. Using a third party 
battery can damage our products. Please note that when such damage 
occurs, it is not covered by unitech’s warranty policy.
