Laptop Battery Question (Dell)

Here's what's going on... I got a new Dell Inspiron 1100, of course has a new battery. I am not one to use the battery a lot, my laptop is used as on the coffee table 90% of the time, so a battery is not that important. However, I want to keep it in excellent condition.

I keep my laptop plugged up on the ac adapter, and under the couch. I was told that if you leave the battery in a laptop, and leave it on the charger all the time, it will ruin the battery. Right now I have the battery out, to keep that from happening, but its kind of annoying having a big gap in the computer where the battery is supposed to go.

So my question is basically this... is it REALLY a good idea to keep the battery out when it is not being used?

I don't know much about this. But I would hope/assume that notebooks have some kind of power management programing that keeps the battery from being overcharged. All I know is that there was nothing mentioned in my Dell Latitude user manual about removing the battery.

Battery technology has come a long way in a few years. It is complicating depending on the exact battery technology you have.

Maybe this link will help?


most Dell laptops I use have lithium-ion technology. No matter what you do, lithium-based batteries have a lifetime of 2-3 years, so you are eventually just going to be screwed by time.

I think it is safe to leave the battery inside the computer. I agree with Mercury, there has to be some kind of power management running that would prevent the battery from being overcharged. Also, it would take a while for it to actually drain and by then, I'm sure you would have gone out and bought a new laptop anyway. Besides, its nice to have it in there in case you lose power. I keep my battery in my laptop...

pretty much the ideal circumstances for a current technology laptop battery would be as follows....

1. keep battery in laptop
2. avoid operating /storing your laptop in extreme hot or cold temperatures.
3. take the laptop off AC power from time to time, and let the battery power it for 1/2 to hour or so. longer if needed.
4. Once it has been used, go back to AC power and let it recharge.

As long as the battery gets used and recharged occcaisonally, it should last the full 2 to 3 years without issue. Believe it or not, the number 1 battery killer is extreme temp storage. The memory effect of years past is solved for the most part, but it doesn't hurt the battery to get cycled once in a while.
