Lithium ion Battery


3.7 Volt - Secondary / Rechargeable Battery


Lithium-ion (Li-ion) batteries are a type of rechargeable battery commonly used in portable electronic devices and power tools. They are favored for their high energy density, low self-discharge, and long cycle life.



 Main Features 

  • High energy density: Li-ion batteries have a high energy density. They can store a large amount of energy in a small size.
  • Low self-discharge: Li-ion batteries have a low self-discharge rate. They can retain a significant portion of their charge even when not in use.
  • Long cycle life: Li-ion batteries have a long cycle life.  They can be recharged and discharged over 500 cycles.
  • Stable voltage: Li-ion batteries have a stable voltage output throughout their discharge cycle, making them well-suited for use in applications that require a consistent power output.
  • Lightweight: Li-ion batteries are lighter than other rechargeable battery technologies, making them ideal for portable devices and small electronics.
  • No memory effect: Li-ion batteries do not have a memory effect. They do not need to be completely discharged before recharging.
  • These features make Li-ion batteries a popular choice for a variety of applications, including laptops, smartphones, and electric vehicles.
