FAQ:

Q: Do lithium ion batteries go bad?

A: Lithium Ion batteries “go bad” when they are stored in discharged state. It is all about battery voltage. If voltage is too low – undesireable chemical reactions will happen and battery will degrade. If battery is not empty and not used for long time – it will be fine.

Q: What does rechargeable lithium ion battery mean?

A: A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.

Q: Why are lithium batteries rechargeable?

A: Second, lithium is much lighter than other metals used in batteries, such as lead, which is important for small objects such as phones but also for cars that require many batteries. Third, lithium-ion batteries are rechargeable, because lithium ions and electrons move easily back into negative electrodes.

Q: What are the advantages of lithium batteries?

A: High Energy Density: One of the biggest advantages of a lithium-ion battery is its high energy density. To put it straight, lithium-ion batteries can last way longer between charges all the while maintaining a high current output. That makes it the perfect battery for most modern needs.
