Laptop Battery is 33% of what it used to be...

I recently realized that my laptop isn't lasting nearly as a long as it used to. When I first got it, it was reaching battery life of about 2 hours and 45 minutes. Now, it can barely last 50 minutes. I read up on some battery tips and conditioning your battery. They say to condition your battery by letting it run down completely and recharge a few times. It also says that it shouldn't happen to Li-ion batteries. I checked my battery, which happens to be a Li-ion.

So what's going on?

Jam it back in, in the dark.

Batteries slowly die. End of story.

There's nowhere I can't reach.

Every time you recharge your battery you have to regrow a crystalline matrix. As time goes on, it regrows less and less perfectly (due to ), so you have less energy stored within the regrown matrix, so you get less time using your laptop before it runs out of juice.

Li-ion batteries still have the same problem, it's just that they're a lot better than some older technologies, so it takes longer for them to have this problem.

This thing is sticky, and I don't like it. I don't appreciate it.

That's what I thought, but surely these batteries don't succumb to 33% of battery life within a year...

I am a dolphin, do you want me on your body?

Mine did. Mine was horrific in battery life after the first year.

It also depends how often you recharged it. If you are constantly running high-end apps that take a lot of power and hence require a lot of recharging, then that would speed up the process.

My advice is to get a new battery. Or...if you have Vista or can get ahold of any other battery checking program, use that to see what's going on.

I was speaking idiomatically.

Alright, I need some battery advice.

My battery is just getting progressively worse, and Acer doesn't provide replacement batteries. So I took it upon myself to go find a replacement online. So I find out what kind of battery I have and try to find some. This turns up 0 results.

I then type in the model of my notebook, which turns up multiple results. The thing is, It's a different model than the one I currently have right now (The battery is a different model, the notebook is the correct model.) The battery looks like it'd fit in the notebook fine, but my battery also says to replace only with a battery of the same kind only. Not doing so will risk battery explosion and all sorts of bad things. I then look at the specs of my current battery, which says 4400.00 mAh capacity and 14.4V voltage. The specs of the other battery that claims to be compatible matches except for the voltage, which says 14.8V voltage. I'm pretty sure this isn't a good combination.

So should I just ditch this notebook soon and find another one?

What kind of toxic man-thing is happening now?

Why don't you give Acer a call? I find it highly doubtful they can't provide you with new parts of recent systems.

FELIPE NO

Ok, I've got a related question. I just bought a new laptop (I haven't owned a laptop since my 133MHz model in college), and it's going to be sitting on my desk, not going anywhere 99% of the time. Should I be leaving it unplugged unless it needs a charge, or is it ok to leave the AC adaptor in all the time?

The first time I used it unplugged, it ran fine for an hour or so, then I noticed the battery was down to 50%, and my system was configured to "high performance". I changed the performance to "balanced", and a few minutes later I got a BSD and the computer rebooted. At the time, I had a few things running (Trillian, StarOffice and IE), but nothing really intensive.
