A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

[6] [7] The higher the required discharge rate of a battery, the better matched the cells should be, both in the type of cell and state of charge, in order to reduce the chances of cell reversal. In some situations, such as when correcting NiCd batteries that have been previously overcharged, [8] it may be desirable to fully discharge a battery ...
Lead–acid batteries should never be discharged to below 20% of their capacity, [67] because internal resistance will cause heat and damage when they are recharged. Deep-cycle lead–acid systems often use a low-charge warning light or a low-charge power cut-off switch to prevent the type of damage that will shorten the battery's life. [68]
Louisville [b] is the most populous city in the Commonwealth of Kentucky, sixth-most populous city in the Southeast, and the 28th-most-populous city in the United States. [a] [11] By land area, it is the country's 24th-largest city, although by population density, it is the 265th most dense city.
The Simon was commercially unsuccessful, particularly due to its bulky form factor and limited battery life, [12] using NiCad batteries rather than the nickel–metal hydride batteries commonly used in mobile phones in the 1990s, or lithium-ion batteries used in modern smartphones.
