Default Any way to limit my ASUS 1215B's battery charge?

My notebook doesn't get unplugged very often and I was told keeping it at 100% would cause the wear level to rise. Is there any way (software/hardware) to limit the charge to 40, 60 or 80%?

There really isn't a way other then that supa said. Overcharging a battery, aka leaving it plugged in all the time will damage it, causing it to lose the ability to hold a charge as well over time. If your laptop is plugged in all the time, charge the battery up, then just remove it. This will not damage the laptop, as there is no battery to overcharge, and it won't damage the battery as well it won't be getting overcharged either.

It`s been a while since I was involved in the maintenance of batteries, but my understanding is that the new(er) lithium based batteries do not suffer from the same memory issues (those described by the OP) as early rechargables.

Lithium-Ion batteries don't suffer "as much" as previous battery generations have. But overcharging still has an affect on them. I'd go with charging the battery to full then removing it as was previously stated.

It's actually not the battery memory that is the problem. Batteries work by chemical reaction (redox reactions specifically) as this reaction occurs electrons are released and these power your computer. For rechargeable batteries this process can be reversed by adding more electrons (AKA plugging them in). However while these reversible reactions take place small amounts of irreversible reactions occur, so whenever your battery is plugged in or it is draining it loses a bit of life.

Having extra heat also causes your battery to degrade faster (the extra energy fuels the permanent reactions) so using the laptop while charging while not a huge deal will also degrade it faster.

Amazing what you learn in first year chem.
