Does this exist: Fake Battery Cover for when laptop is plugged in

Hey Folks -

I know some people try to save Battery Charging cycles by removing the battery when it is plugged in. In my case, I always have it plugged in (I rarely move it from the desk), but it almost feels too "naked". I was also worried about the fact that dust might get in there.

Thanks!

 

I don't see how removing the battery would save battery life at all. In fact, I've found that the longer you leave a battery sitting there with no charge on it, the quicker it is going to die. the only way it would save you battery life is if you were constantly unplugging and plugging it back in, but in that case you would need to have the battery in it anyways.

 

That's not how it works.
Charge cycles mean going from 100% down to about 5-7% and back up to 100% again.

Going from 100 to 50% means the battery would last almost twice as long.

100% to 75% even longer.

In any event, whether you use the battery of not Li-Ion batteries have a fixed shelf life of 2 to 3 years from date and manufacture. They can go a little longer but their capacity will be sharply reduced.

 

So it sounds like I'm safe to leaving it in, and plugging and unplugging it in as necessary, because either way 2-3 years I'm going to need a new one...I was just wondering if any behavior can extend the life of the battery to as much as possible

 

Nah, you're good. Just use it and enjoy. If it dies within warranty period, you can get a replacement.

In any event, all batteries lose their capacity over time. A good thing to do is to not let them get down below 20-25% often. Gives you a good use vs. life ratio.

No worries and happy mobile computing.

 

Well, Li-Ion batteries do loose charge capacity when stored near a heat source. In other words the hotter the storage place is, the more charge capacity is lost compared to a cooler storage place. So having your battery in a warm notebook isn't the best place to extend life of your battery. I have mine removed and stored in my desk at around 70% charge, that way if I ever need to go somewhere with my notebook, at least I know I'll have about 2 hours left.
