 6. Operation temperature: -20~70°C

 7.Small size, light weight: 

 8. Good performance at high temperature and high temperature resistance

 9. Low self-discharge rate: < 3% monthly


   Battery Remarks:

1.Never completely discharge lion battery ( below 3.0V under load ).                 

2.Charge fully to 4.2V before first use.                                                                           

3.Never use force to install (insert) liion battery.
