I feel like a complete technological ignoramus posting this but it's the first time I've had the problem:

The battery of my laptop, purchased around 2 1/2 years ago, has suddenly become very unreliable when the machine is not plugged in. What I thought would be a simple procedure, i.e. replacing the battery, seems much more complicated with a glut of info online on 'fake' replacements, an 80 price tag on the battery, and no clear info as to which models accept which battery.

Simple question - is there any downside aside from electricity costs to just plugging the machine in as and when I need it? As I understand it, this isn't a problem for lithium-ion batteries, but I wanted to doublecheck with any tech-savvy people here.
