Rechargeable battery Xtar R6 / AA 1,5V Li-ion 2000mAh with protection

These include:

• higher rated voltage - 1.5V (Ni-MH has only 1.2V)
  
  Some devices, e.g. blood pressure monitors, unfortunately work much shorter on Ni-MH batteries due to lower voltage. On alkaline batteries, on the other hand, they last much longer.
  
  
• constant voltage at all times
  
  The voltage on this battery from the very beginning to the end will be 1.5V. Thanks to this, e.g. in flashlights, we will be able to enjoy the full power of lighting all the time.
• a large number of cycles - more than 1000!
  
  Xtar used the highest quality cell along with a protection system that allowed to obtain a large number of charge / discharge cycles with minimal battery degradation effect.
  
  

• no memory effect
  
  Li-ion batteries are completely devoid of the memory effect. This allows them to be charged at any time.
  
  
• no self-discharge effect
  
  Unlike some Ni-MH batteries, the Xtara battery can last a long time unused - without losing its capacity/energy charge.
  
  
• high current efficiency
  
  The Xtar battery is able to give off a current of up to 2A!
