Other common battery cell types can last significantly longer or shorter periods, such as the smaller CR2016 which will generally last about 40% less time than CR2032. Higher temperatures and longer power-off time will shorten battery cell life. When replacing the battery cell, the system time and CMOS BIOS settings may revert to default values.
In personal computers, Ni-Cd batteries first saw use in the mid-1980s as a cheaper alternative to lithium batteries for powering real-time clocks and preserving BIOS settings. Nickel–cadmium batteries were also briefly used in laptop battery packs, until the advent of commercially viable nickel–metal hydride batteries in the early 1990s. [9]
Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge". A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] Each battery is affected differently by charge cycles ...

It's also reasonable to expect a battery to last longer than that. Tesla's Impact Report for 2022, for example, states that its battery packs only have 12% degradation at 200,000 miles.
The shelf-life of electric vehicle (EV) batteries may be as much as 40 percent greater than previously assumed, a new study has found. Stanford University scientists uncovered this possibility by ...
A lithium-ion battery from a laptop computer . Batteries gradually self-discharge even if not connected and delivering current. Li-ion rechargeable batteries have a self-discharge rate typically stated by manufacturers to be 1.5–2% per month. [70] [71] The rate increases with temperature and state of charge.
