I know there's already some feeds on this but I just can't get one straight answer. Everybody says different things. I have an Asus laptop with a Lithium-polymer. I do game a lot so what's your opinion. I want my battery life to last, so wouldn't keeping it plugged in as much as possible do this? This would minimize the cycles, and I know my laptop cannot overcharge the battery as it only charges up to 97%. I know overheating is the main factor and I will try to keep that under control. I guess I have all the information but just want confirmation that keeping my laptop plugged in won't damage the battery.

  • If your computer allows it, remove the battery when it is about 40-50% charged and put it in a cool location. – bwDraco Dec 28 '14 at 03:59
  • I cannot take out the battery – Jacob B. Dec 28 '14 at 04:04
  • I can understand the advice to take the battery out. But I'd leave it in. Works like a UPS that way. If there's a power outage your laptop keeps going instead of shutting off possibly corrupting things. – misha256 Dec 28 '14 at 04:09
  • I can't take it out anyways. I just want to know if I can keep my laptop plugged in without the battery going bad – Jacob B. Dec 28 '14 at 04:10

The laptop knows how to take care of the battery. It will engage actual charging only when needed. Nothing bad will happen if you keep the adapter plugged in.

DragonLord's advice is spot on if you want to preserve the battery as much as possible. Technically the best place for a Li-Ion battery to sit at is around 50% charge. But then what's the point. That's getting too OCD for me. The purpose of a battery is to make a laptop portable. It also serves as a kind of UPS, so that if there's a power outage, your laptop doesn't just shut off potentially corrupting data.

So go nuts, leave it plugged it to the wall, it's all good :-)
