Xtar R03 / AAA 1.5V Li-ion 680mAh battery with protection (BOX) - 4 pieces

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 light all the time.
  
  
• a large number of cycles - over 1200!
  
  Xtar used the highest quality cell with a protection circuit, which allowed for a large number of charge/discharge cycles with minimal battery degradation effect.
  
  

• no memory effect
  
  Li-ion batteries are completely devoid of memory effect. This allows you to charge them at any time.
  
  
• no self-discharge effect
  
  Unlike some Ni-MH batteries, the Xtar's battery can sit unused for a long time without losing its capacity/energy charge. 
  
  
• high current efficiency
  
  The Xtar battery is able to give off up to 1.5A of current!
