Is it bad to always have your laptop charging?

Question

i want to kno

Answer 1

Depends on the laptop

Most are Ok to leave plugged in (just like a modern cell phone battery) Circuits in the computer will prevent overcharging.
BUT... on older laptops once the battery is fully charged and you are NOT using the laptop unplug it.

See your owners manual or download a copy for the computer manufactures web site and follow their recommendations.

Answer 2

basically, a laptop battery is almost the same as a cellphone's battery. same type, same functions to power up the device. different amounts of capacity and cells.

what makes a difference is that a laptop is a high power device rather than a cell, considerably a low power device. in any case, to your question, a battery would go bad if it is continuously left charging. think it in simple terms. if you constantly added water to a balloon, will in burst in the end? the same goes for a battery, except less explosive and extravagant. the battery cell will get damaged from excessive charging and the cells containing the lithium ions will disintegrate and stop conducting electricity. thus so, your battery life will slowly drop from the usual average of 4 hours to around a 'maximum' of 1 hour, based on Intel Centrino's technology.

another factor to consider is of the battery cycle count. it is calculated as a full charge to a percentage of below 35-40% and then 100% again. if a battery is new, it can take more power. as it ages, and as the lithium ions lose conductivity, battery power capacity starts to be decrease. it is due to the lesser ions that can conduct electricity between the nodes of the battery itself. and for information purposes, an average battery can sustain up to around 120 full charges before the battery starts to lose its effectiveness.

if you are to plug in your laptop into a wall outlet everyday, take out the battery from the laptop to avoid overheating from overcharging the battery. even with current technology to minimise current flow when the battery is fully charged, a small amount of current still goes to the recharge the battery due to the fact that the battery will still lose power charge if left unused.

whenever you use your battery, try to use the battery till it has a remaining 10% before charging. it is to condition the battery and to remove any 'memory' effect. contrary to all advertisements, 'memory' effect is still existent in lithium ion batteries, though the effect is lesser and not as noticeable as a Nickel Cadmium. this conditioning will slightly increase your battery's capacity to hold more power.

Answer 3

Yea, I agree with the above as I had a Battery Die in less than a year. I did not think. Now when it charged I remove the battery when I on the wall plug. Then when I use the Battery I drain it down all the way before I recharge. They last a long time doing this.

Answer 4

Yeah, you may over charge it and then you'll have a power problem. It's also very bad for the battery. The best way to make your battery live longer is to work on the laptop till your battery dies and your system hibernates, and you have to set the power option to "portable/laptop" while working on the battery. When you charge it, set the power option to "Always on". Once the battery is charged, remove the charger, and set the power option to "portable/laptop" again.

Answer 5

lithium ion batteries can hold only so much charge and that charge must be released before you charge the battery up again

otherwise you begin to for a membrane inside the battery that membrane will keep getting bigger the more you charge your laptop when it is not needed

eventually the membrane will become so thick no electricity will be absorbed into the chemicals. Thus, you battery will not work anymore.

Answer 6

No it is not bad. I never take my battery out of my laptop. On a new laptop it does not matter, but on a old laptop it is a different question

Answer 7

I am a support guy and I say no BUT, you should let you battery fully discharge evey so often. Also you should read the manual regards the care of the battery for your specific system.

Answer 8

My experience with Easynote laptop was that battery diode was broken by constant charging so in this case I would say yes.

Answer 9

sure it does placed on out your battery swifter. Its surely not a solid theory because of the fact ultimately a clean battery will value you someplace alongside the lines of one hundred or so funds. Wait til its the backside (10% or so) till now recharging. in basic terms use the battery in case you plan on shifting around plenty and not table sure. attempt to apply the charger on my own as much as conceivable to stay away from consistent utilization and charging/discharging of the battery. ultimate of luck.

Answer 10

Yes, dont overcharge your battery or youll regret it.

refer to your manual. Average time is 2-4 hours MAX depending on battery life.
