Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [ 1 ] [ 2 ] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after ...
The KiBaM battery model [3] describes the recovery effect for lead-acid batteries and is also a good approximation to the observed effects in Li-ion batteries. [1] [4] In some batteries, the gains from the recovery life can extend battery life by up to 45% by alternating discharging and inactive periods rather than constantly discharging. [5]
They can result from improper clock sources [3] and buffer size. Also, clicks can be caused by electric devices near the computer or by faulty audio or mains cables. [4] In sample recording, digital clicks occur when the signal levels of two adjacent audio sections do not match. The abrupt change in gain can be perceived as a click. [5]
In fact, once the load is removed, the battery voltage will recover, [3] and more energy can again be drawn out of the battery. This is because the law applies specifically to batteries discharged at constant current down to the cut-off voltage. The battery will no longer be able to deliver that current without falling below the cut-off voltage ...
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.

Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
