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. [2] [3] In general, number of cycles for a rechargeable battery (the cycle life) indicates how many times it can undergo the process of complete charging ...
While the state of charge is usually expressed using percentage points (0 % = empty; 100 % = full), depth of discharge is either expressed using units of Ah (e.g. for a 50 Ah battery, 0 Ah is full and 50 Ah is empty) or percentage points (100 % is empty and 0 % is full). The capacity of a battery may also be higher than its nominal rating.
A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate.
In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready.

How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. [2] Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lower self-discharge rates than older types of secondary cells.

This battery pack features an expected range of over 400 kilometres (250 mi), 4C fast charging capability, the ability to be discharged at −40 °C (−40 °F), and no difference to the driving experience at −20 °C (−4 °F). By 2025, around 30 different hybrid vehicle models are expected to be equipped with this pack. [81]
