Lithium-ion batteries is almost everywhere nowadays, in your phone, in your laptop. According to the link below,
The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
Please notice that 300 to 500 charge cycles or 2 to 3 years are not the maximum life of a lithium-ion battery. There are many factors which could prolong the life of your lithium-ion batteries. (I have a Compaq laptop bought in 2005, right now the battery is still working, though I did not pay a particular attention to how to prolong its battery life. Depending on the makers, my Lenovo laptop’s battery died in 3 years).
If you don’t use your lithium-battery, a shelf life, which could be called, will be at least 10-12 years. (I have recorded the daily voltage drop of a lithium-ion for more than 10 years, there is not much drop from the initial voltage).

The following conclusions are based on links above:
- Partial charge better than a full charge
- Operate in SoC (state of charge) between 30-80%
- Deep discharge wears the battery down
- Store in cool place partially charged
- Do not charge below freezing
- Do not charge above 50°C (122°F)
- Rapid charge in 3 hours is recommended
- Fast charge in 1 hours is avoided
