Battery Removal During Charge?

is it safe to remove the battery while being powered with ac? or do i have to power down the system, remove the battery, then boot up again. also vice versa, can i be powered with ac, then insert the battery into the system and unplug the ac?

 

Feel free to pull the battery out when the system is on AC, conversely you can insert the battery while the system is powered on. Check out the Battery Guide for more information.

 

I do that all the time

I've certainly done it before, its difficult on my current laptop because of the screen (hinge surrounds the battery, can't take it out with screen open). I would just be careful, don't but the ac adapter, you might lose contact and poof, your unplugged with no battery and you didn't save...oops.

 

I do it all the time, my battery is easy to unplug. But once I was in a hurry and wanted to move desk so I put the battery in and pulled the AC. It went off and I figure I pulled it out too quick. So now I make sure the battery is in before I pull it out.

 

I've seen ASUS techs remove batteries like that, so i assume its pretty safe.

 

I don't think there's a problem there. Many people do it all the time without any issues.

 

aight thanks guys

 

Why?

I never remove my battery.

 

Hi yan,

I was just thinking that it is safe to do it that way. But since you asked:

I use my comp 90% of the time without a battery cause my workplaces (I work on many locations) have power and I usually work longer than a battery can last. The second thing is that the battery lives much longer that way. I have an Asus M6N battery that after 5 years is still very good - only 17% wear.

My current battery on Prestigio isn't very good but I can say one thing - my brother has a 6 months newer battery than mine (2 years old) and it is always in and notebook is used every day (like mine). It is practically dead, and he needs a new one. Mine still holds 2:20 when needed (and I have a screen that eats a lot of energy).

So this is my third notebook and after many batteries on the first one I decided to remove battery for the most of the time and then put it in when I actually need it. It is cheaper. The thing is that whenever you plug in it will start to charge, even if the battery is 100% full. After a while it will stop charging, but electrons will still flow through the battery. That causes deterioration of the battery substance (Lithium polimer) and it cannot be charged properly anymore. Cycles of flowing electrons either charging or discharging the battery cause battery to wear. That is why I want to keep number of cycles down to the minimum and thus I put battery in only when I need it. I charge it from to time obviously and discharge too, but If I work for hours on the main power, why would I need battery? It is just dying there. Now it is dying much slower in my backpack!

Cheers,

Ivan

 

This is not true. It was that way on some older notebooks, but newer notebooks won't charge battery until it is under some level (usually around 95%). The only concern is higher temperature, but I have almost 7 months old notebook, with battery always plugged in and running at least 10 hours daily on AC and the battery is still almost as new. Also, the battery lasts longer when it is stored with lower charge level (40%; check battery guide for details), but if you store the battery charged to 100%, there is almost no difference in lifetime if you leave it plugged in or store it apart.

 

i have another question now, since this thread is still going and it is about batteries, i decided not to create another thread.

i ordered a battery from ebay, it has 21% wear level from mobilemeter reading. it charges to 100% (which is like 78% from taking the number it charges to full, dividing it with the charge it held when new).

i had a conflict with gateway and after sending in my proof of purchase, they decided to send me a new ac adapter (mine was buzzing) and battery (since i never got a battery with this laptop to begin with). what should i do with that new battery when i receive it? just store it? or do a full charge and test it out, discharge it and store it?

 

Well I must have an old style battery then. I am glad everything is fine with your battery. Did you try NHC battery wear index? My is already 17%. But anyway - I guess everyone can do whatever he/she wants with a battery. All I wrote is based on my personal experience.

Cheers,

ikovac> NHC Battery wear doesn't work for me, NHC detects battery as 15V, but battery has only 10.xV. Right now it reports 0% battery wear...

But, from battery data, the wear level should be around 7%.

 

Hm. I guess number of cells has a great impact on wear level. I really hope my next laptop will have better battery.

Cheers,

Ivan
