Could someone check my post about laptop batteries?

Dear users,

Could you please check if there are any non-native sounding sentences in the following paragraph? Any grammar errors? Thanks!

Hello. Can I ask a question here? I bought a new small ultrabook a month ago and I'd like to make sure that the battery lasts and stays in good shape as long as possible. I've recently read a few articles saying that the best practice is to keep the battery charged between 40-80%. Now, if I'm at home, it's quite easy, but what worries me is that I every battery has a certain number of charge cycles. The battery goes down from 80% to 40% quite quickly, so... every time I plug the charger in and out, I'm "using" another charge cycle, I guess. Does that make any sense? If I'm at home, should I just keep the laptop plugged in all the time? And what about leaving it plugged in for the night? Thank you! I hope it's OK to post my question here.
