Xtar R03 / AAA 1.5V Li-ion 750mAh Battery with Protection (BOX) - 4 pieces

These include:

• higher nominal voltage - 1.5V (Ni-MH only has 1.2V)
  
  Some devices, such as blood pressure monitors, unfortunately work much shorter on Ni-MH batteries due to the lower voltage. On alkaline batteries, however, they work much longer.
  
  
• constant voltage throughout
  
  The voltage on this battery will be 1.5V from the very beginning to the end. Thanks to this, for example, in flashlights, we will be able to enjoy full brightness all the time.
  
  
• large number of cycles - over 1200!
  
  Xtar used a high-quality cell along with a protection system, which allowed for a large number of charge/discharge cycles with minimal battery degradation effect.
  
  

• no memory effect
  
  Li-ion batteries are completely free of memory effect. This means they can be charged at any time.
  
  
• no self-discharge effect
  
  Unlike some Ni-MH batteries, the Xtar battery can be left unused for a long time - without losing capacity / energy charge. 
  
  
• high current efficiency
  
  The Xtar battery can deliver a current of up to 1.5A!
