  2. Trickle charging - Wikipedia

    en.wikipedia.org/wiki/Trickle_charging

    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.

  3. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A smart battery requires a smart charger. Some smart chargers can also charge "dumb" batteries, which lack any internal electronics. The output current of a smart charger depends upon the battery's state. An intelligent charger may monitor the battery's voltage, temperature or charge time to determine the optimum charge current or terminate ...

    en.wikipedia.org/wiki/Compaq_LTE_Elite

    [26]: 182 In particular, Farrance singled out the LTE Elite 4/75CX for its processor and battery life, respectively rating 10 percent faster than other laptops in its class and lasting six-and-a-half hours on a single charge in an average use-case scenario. Farrance quibbled with the display's brightness slider, which failed to dim enough to ...

  5. Laptop - Wikipedia

    en.wikipedia.org/wiki/Laptop

    A laptop's battery is charged using an external power supply, which is plugged into a wall outlet. The power supply outputs a DC voltage typically in the range of 7.2—24 volts. The power supply is usually external and connected to the laptop through a DC connector cable. In most cases, it can charge the battery and power the laptop ...

  6. Memory effect - Wikipedia

    en.wikipedia.org/wiki/Memory_effect

    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 ...

  7. Charge cycle - Wikipedia

    en.wikipedia.org/wiki/Charge_cycle

    A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load.The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time.

  8. Charge controller - Wikipedia

    en.wikipedia.org/wiki/Charge_controller

    A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. [1] [2] This prevents conditions that reduce battery performance or lifespan and may pose a safety risk. It ...

  9. Smart battery - Wikipedia

    en.wikipedia.org/wiki/Smart_battery

    A smart battery or a smart battery pack is a rechargeable battery pack with a built-in battery management system (BMS), usually designed for use in a portable computer such as a laptop. [ 1 ] [ 2 ] In addition to the usual positive and negative terminals, a smart battery has two or more terminals to connect to the BMS; typically the negative ...
