It may also prevent completely draining ("deep discharging") a battery, or perform controlled discharges, depending on the battery technology, to protect battery life. [ 3 ] [ 4 ] The terms "charge controller" or "charge regulator" may refer to either a stand-alone device, or to control circuitry integrated within a battery pack, battery ...
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 Huawei MateBook series is a range of laptops produced by Huawei. They were originally released on the eve of the opening of the Mobile World Congress on 21 February 2016.

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.
Dan Seifert from "The Verge" praised the laptop's display, performance and design saying "Huawei’s new MateBook X Pro is the best laptop right now." Seifert also compares the keyboard of the Matebook X Pro to Apple's MacBook Pro saying "The keyboard has low travel (1.22mm), but it’s not as low profile or annoying to type on as the keyboard ...
By 1990, Taiwanese companies manufactured 11% of the world's laptops. That percentage grew to 32% in 1996, 50% in 2000, 80% in 2007 and 94% in 2011. [7] [8] The Taiwanese ODMs have since lost some market share to Chinese ODMs, but still manufactured 82.3% of the world's laptops in Q2 of 2019, according to IDC. [9] Major relationships include: [10]
Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment caused by factory or design defects, excessive gas generation, or physical damage to the battery.
