new laptop. once battery is charged. can battery be taken out and just use the plug/conv. wire? and use the battery when not in the house? or will info be lost because of battery taken out? does leaving the battery in the laptop effect memory charge? should the battery be used to almost drained then charged back to 100 % once a week or more? thanks for any info on proper use and longer life of a laptop battery. the battery lists for $120, seeking info on makeing it last longer. thanks for all info or sources to check. our desk top cpu is about on it`s last mb. so we thought we would get a new laptop and make some room on the desk. it didn`t even come w/ an instruction manual. have to get the info off line.

I run all my laptops without the battery installed.
Leaving the battery in the laptop will effect memory charge (SOME of the newest laptop batteries say they won't................not willing to try this for $120 battery).
I completely discharge my laptop batteries about every other month. Then fully charge.

Another thing, use the battery till it needs a re-charge it'll last longer.
If you run it for a few minutes on battery, then charge it, the time between re-charges and amount of time your laptop will run is considerably shorter.

Most modern laptops are recommended to be run WITH the battery installed at all times.

One of the main reasons, or so I'm told by a computer-knowledgeable friend, is that most laptops can't run at full processor power on just the wall power supply. Instead, the battery is used as a "reserve" to fill in for periods of high demand(which will generally be short-lived) even when plugged into the wall.

If the battery is removed, the computer will reduce the power across the board to prevent even coming close to needing the extra reserve of the battery. On my computers, I notice the loss in performance without the battery even when doing only moderately demanding tasks like watching Youtube videos.

I am a full time(PhD) student, and my laptop is my only computer. I beat on it probably 12-14 hours a day, not necessarily doing demanding work but just a LOT of reading and typing. I leave my computer plugged in most of the time, although I typically will end up doing close to a deep discharge once a week or so. I don't plan it or have a formal schedule, it just happens. My last few computers have lasted me about 1.5- 2 years each, and all of them have still had good battery life when they were retired for other reasons.

I'm told that the biggest enemy of modern batteries is heat, and that a battery that is allowed to remain relatively cool both in storage and in operation will still retain a significant portion of its capacity.

By the way, my current computer(the one I'm typing this from now) is a 13" Macbook Pro that I've been using since the end of March. The newer Apple computers don't have a battery that is intended to be user-serviceable. Apple states that the battery will retain 80% of its capacity after 1000 charge cycles, and will replace the battery if it falls below 80% within the warranty period. From my own experience, it doesn't look to me like I'll need to collect on this particular aspect of the warranty, and I don't know of anyone else who has needed to either.

Our Dell laptop battery is supposed to be one of those batteries that don't develop a memory. We got it back in May and so far so good. We haven't had a problem with the battery yet, it still holds a 5 hour charge and hasn't required any special treatment. We did have to send the laptop in to have the hard drive replaced and that took about 10 days. But it's back and working great.

Hope you don't have a power flicker with the battery out if you're working on something important.

Been there.... Done that.

answered my question. thanks for your input/info. it is a high def laptop. it is supposed to cut out all programs that are not being used to make it run faster/ better. everyone have a good weekend and new year.-rich

I run my laptop without the battery installed. If I leave the battery installed, it overheats and shuts off after 20 mins of use. I'm sure the battery needs to be replaced, but I have a hard time spending $60+ on a battery for a 4 year old computer.

I am a computer guy, went to kolledge, have certs and such. Modern laptop batteries are Lithium Ion and do not suffer the memory issue of Nickel Cadnium or Nickel Medal Hydroxide. A battery's enemy is heat so you will get longer life from it by using it....not allowing it to fully die, and charge it. Lithium Ion battery's require a more safisticated charging circuit....thus when the battery is charged it goes into a trickle charge as needed or sits fully charged until used. Modern laptops run hotter because of faster CPU and ram speeds. Leave the battery in it and you will be fine. If you are worried about heat, you can get laptop cooling pads that have fans in them to act like a heat sink for the bottom of the laptop and run off a USB port. I hope this helps.
