"Fully charged (100%) Consider replacing your battery"

The battery icon on my Acer laptop's Win7 desktop turned red and I got the above message. I seldom use it in battery mode, but after seeing the warning, I ran the battery down 20% and it recharged normally. Online, there seem to be a variety of possible reasons, including Win7 problems and............... well, the battery actually needing placement.

But that's not really my question, which is: since I don't use the laptop in a mobile way at all, but as a kitchen table device, would there be any downside to just yanking the battery out until I get it sorted? (My instinctive thought to my own question is 'no, go ahead,' but my instinctive ideas about computers are not always correct.

Thanks for any advice.

 

I have a couple of laptops always connected without a battery (battery is too old) used as desktops for more than a year and had absolutely no problems so far. My Samsung machine came with a special program which cuts the charging once it reaches 80%, apparently it extends the battery life significantly.

 

Thanks for both factoids, they are helpful.

 

It is fine to leave out your battery when using the computer. The latest says that it is good to store the battery at about a 40% charge though. This will hopefully enable the longest battery life.

Best wishes

 

Thanks. There seem to be a number of indications that keeping a battery at 100% forever is not the best approach. I wish I had known that earlier.

 

I've been running my Toshiba laptop without the battery for over 3 years now.

 

Thanks.

If you unplug such a beast, will it hold what's in RAM for a short while?

 

If you unplug it, it will die pretty much straight away.

 

I've got the exact same thing with my Acer. The only reason I keep the battery in is for unexpected power failures. It gives me time to shut down my machine without potentially damaging my HDD.

I live in an area where I can lose power easily so I like the assurance the battery gives me.

 

I ran the battery down to 15%, and it recharges at a rate of about 1.3% per minute.

 

My Lenovo which is plugged in 95%+ has a Battery Protection Mode when set only charges to 60%. This will at least double the life of it.

 

Is there any respected studies regarding this? Such as keeping LiPo batteries at less than fully charged condition might prolong their life over years? I occasionally tried to find if I can find something solid but almost everything I find are opinions from people and sometimes companies.
