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 ...
When power is extracted continuously voltage decreases in a smooth curve, but the recovery effect can result in the voltage partially increasing if the current is interrupted. [2] 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.
Also it is possible to lower the memory effect by discharging the battery completely about once a month. [citation needed] This way apparently the battery does not "remember" the point in its charge cycle. An effect with similar symptoms to the memory effect is the so-called voltage depression or lazy battery effect. This results from repeated ...
Turns out, being lazy can be a good thing. Although it may feel counterintuitive to slow down and take a step back from your usual grind, science shows there are many physical, mental and ...
For example, consider a battery with a capacity of 200 Ah at the C 20 rate (C 20 means the 20-hour rate – i.e. the rate that will fully discharge the battery in 20 hours – which in this case is 10 A). If this battery is discharged at 10 A, it will last 20 hours, giving the rated capacity of 200 Ah.

Conditions in the trackbed (roadbed) which create stray electrical signals, such as muddy ballast (which can generate a "battery effect") or parasitic electrical currents from nearby power transmission lines. Parasitic oscillations in the equipment that controls the track circuits. [4]
