Leaving a laptop unused

I've just bought a smaller/lighter/better laptop for uni... but my current laptop still works pretty well and I'd like to keep it for the future.

If I drain the battery and leave it unused for (e.g.) 8 months will it still function normally when I next turn it back on?

Thanks

Maybe or maybe not.........it will certainly cause damage to the battery cells. I would suggest if someone at home could potentially use or turn it on every few weeks or so and check the battery to charge, etc

Store it in a cool and dry place at 40% charge and it will be fine.

Do NOT drain the battery for storage. Stored batteries will lose energy over time but at a slower rate and if your battery discharges below a certain level it will destroy it. The 0% battery level is not actually zero energy in the battery, you may think that the battery is drained completely but it actually isn't. This system is in place so it doesn't destroy the battery.

40% charge level is the best way to store it. The laptops sold in shops are charged to about 40% and then packaged.

So 40% and take the battery out?

Why not 100%? (just out of interest) - surely less chance of the battery completely draining??

@adam132 - this post might should be helpful to you too.

Heat and high charge voltage put stress on the battery. When a bettery is exposed to heat it puts stress on the battery and dwelling in a full state-of-charge (high voltage) also puts stress on the battery. Hence a full charge deteriorates battery faster than a battery at 40% due to higher peak charge voltage.

This is a good table for OP:


So lets say you have a brand new battery which has 100% battery capacity. If you charged it to 40% and you left it at 25 C for a full year, you would still have an estimated 96% capacity left after a year compared to only 80% if fully charged and left for a year. (refer to table)
