Whether to use laptop permanently linked to power supply
For years I have used my laptop with the power supply remaining connected, even if the Li-ion battery is showing fully charged. (Obviously that would maintain the battery at 100%).
Now my friends are advising me that this is bad practice and will wear out the battery quicker (although the battery that came with my Acer lasted four years doing this). They say that I should charge the Li-ion battery to 100%, then disconnect and run it down to 5% or 10% before recharging to full again. As this is such a basic issue I am not citing specific models, but can do so if there is not one right answer across the board. Last edited by Madge2; April 1st, 2013 at 08:49 PM. Reason: typo |

every laptop I had was basically plugged in 24/7 while every so often I would let it run down but not out. Imo, I believe it does do some harm in the long run but usually by the time that happens, it has been replaced. Once thing to note, lithium batteries can by harmed by letting it run completely out.
You can do a search online and you will find arguments for both sides. my advise is to do what you feel comfortable with. |

Thanks Renegade
Incidentally I have just removed a defective battery from an HP Pavilion notebook and I am using it now plugged into the mains power. This has solved some problems from which I have suffered lately. But is there any downside to doing this indefinitely? I don't need this notebook to be portable. |

In the olden days when all notebooks used NiCad batteries, leaving the charger plugged in all the time did cause problems as NiCad batteries have a problem with voltage depletion or voltage depression phenomenon, often called "Memory Effect" - where they got used to being at a particular charge status, and once they dropped a bit below that, they tended to drop drastically. Or if they were kept nearly discharged for long periods of time, they would not take a full charge. To prevent memory effect, it was necessary to always fully charge and then fully discharge the batteries so they would work properly, and avoid keeping them at a constant charge status for long periods of time.
But later notebooks used Nickel Metal Hydride (NiMH) batteries, and the latest notebooks use lithium-ion (Li-ion) and these batteries do not suffer from the same memory problems as Ni-Cad batteries so you can safely keep them plugged in 24/7. |

If there's not a "smart" circuit that senses when the battery is full and shuts off the charger accordingly, then the battery is going to have a charge constantly pumped into it, which will be burned off as heat, lowering battery life.

We'll finish this by playing your word game on your turf. Let's agree that the battery says "lemme have it", to which the charger does. No matter how much you just have to be right, the end result is that heat eventually destroys the electrolytes of a battery. See ya down the High Road. *snicker* |

You are right, I didn't have to say anything. I could have let the mis-information just slide. But you had a tissy-fit, made it personal and launched puerile insults instead of keeping it technical and non-personal. And you are still tossing out insults. Junior? Yeah, right. I'm the immature one here. No more wasting time. I'm done here. |
