Acer Aspire V 15 Nitro Black Edition turns off when not plugged in, starting from a few seconds to a few minutes...

The laptop worked fine for awhile, then suddenly it randomly turned off when unplugged and it always turns off within a few seconds to a few minutes of turning on now... Still works fine when plugged in though.

If it works when plugged in but not when unplugged you probably need a new battery.
