✔ Best Answer
If your battery is fully charged, remove it and run off the AC, once the battery is fully charged, the constant AC going through the charging unit makes the battery get warm, by removing the battery, when it is fully charged it will get less hot and help to maintain battery life. Use battery power until it wants to shutdown, and then give it a full charge. While batteries do not have a memory to the extent the older ones did, it is still good to drain the charge and give them full charges, as opposed to plugging it into charge everytime the battery dips a bit.

I agree fully with the above statement.

You have to be a little bit crazy to keep you from going insane.

I totally disagree. When the battery is fully charged, the charging circuit cuts off and no current goes to the battery. It it perfectly fine to leave your battery in all the time

THX... -- While it is true that the charging circuit does cut out to the battery, leaving it plugged in does cause wear to your charger, use more energy since power is going through the transformer whether it reaches the battery or not, and leaving it plugged in also wears the charging jack so that after a couple of years, you no longer get a good contact and might actually damage it severely it it takes a bad enough bump when plugged in.
What I mainly agree with is that while Lithium batteries do not have the problem of battery memory that NiCads metal hydrides have, it is still better to run them down most of the way most of the time. Of course, when you need the full charge for the next day and it still has some charge, then by all means, charge it. Just not all of the time. When you get home and you plan on using the computer, use it but keep the charger near by and when it gives you the battery low warning, plug it in and continue to use it as needed. Then leave it overnight and unplug it in the morning.
I strongly do not recommend plugging it in as soon as you get home and leaving it in all of the time until you need to go out with it. That way leads to less usable battery life a lot sooner as well as the other problems I mentioned above.

Hi Fingers,

Sorry but that is just not true, it is not good to run them down all the time. The more you use the battery the sooner it will reach the end of its life. The average lithium polymer battery has a lifespan of approx. 1000 full charges before you notice a large degredation in run time.

Wear to your charger? I work in the the tech department for a large business. Out of the thousands of laptops and tablet PC's we have, I've had maybe two chargers go bad. And a $20 - $30 dollar charger is certainly cheaper than a $60 - $100 dollar battery.

We have clinicians that use HP tablet PC's and they abuse the crap out of these things and I've only had to send a few in because of issues with the power jack on the tablet. This is out of approx 700 tablets we have.
