6 FAQs about [Battery and power supply OK ]

Is it bad if a laptop battery is fully charged?

This page has a good answer: "it depends" The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.

Should I keep a battery in my laptop if it's not needed?

Thus, keeping a battery in the laptop when it's not needed is very detrimental to it's life span. Also, it increases the risk of applying "top-up" charges, which again will shorten the life span. From a view point of your battery's health you should keep the laptop plugged into the wall and unplug the battery from the laptop.

What happens if a battery adapter is plugged in?

I found out that when battery is in and then the adapter is plugged, the adapter shuts off (output voltage gradually drops to 0), and the only way to restart it is to unplug it from AC power and plug it in again. Personally I wouldn't risk it. If, as you say, the power cord is short there's a good chance it'll come out during the operation anyway.

Should you keep a battery on a power cord 24/7?

So, if the heat matters, and modern charging sets are effective enough to bypass battery when it's been charged, thus causing no heat, one may consider keeping a device on power cord 24/7 risk-free (in context of electrons and heat and battery and stuff)? Any other factors involved? In theory, yes.

Can a power adapter run off a mains power supply?
