An Hour or A lot less
Most laptop batteries definitely will charge from 80 to 100 percent of their capacity in about about one hour. Some older models may perhaps charge more slowly, while some newer models will command faster. If the battery request process is taking in excess of an hour, keep as the primary goal that a laptop battery doesn't degree of full charge to perform.
More than an an hour
While some laptop batteries are designed to stop charging once 100 % of their capacity is actually reached, some models continue to draw in energy. Overcharging a battery will shorten it will be lifespan and lower it's efficiency. An AC adapter should be unplugged if the laptop will not be used any time quickly.
Bottom Line
Ultimately, the question hinges on the type of laptop and the method of battery. One way to decide the charge speed is to simply keep an eye on the laptop's battery meter. The location of this meter varies according to the operating system.
