Recalibrate battery

hey people
My aspire one had 11% wear level on battery now, and recalibrating doesn't help either, but I want the battery to re-learn again, how do I do that?
I fully discharged the battery and waited till the laptop fully shut off by itself. Waited for 3 hours.
And fully recharged it, and still no hope, did I do anything wrong here?
Any thing that will make it relearn? I know that the battery wear level is not 11%, its impossible, since I had this machine for 1 month now.
Any help would be greatly accepted!

 

lithium ion batteries don't have memory (they actually prefer trickle charging, if anything). the wear is the physical degradation of the electrolyte and happens regardless of charging cycles. what are you doing to measure the wear?

 

I used Everest to measure the wear level. It displays my battery correctly and even tells you the voltage battery is operating now.

 

but doesn't everest just pull the info from the bios? that means the bios could report basically whatever it wants.

 

Everest is actually a program not only for BIOS, but it is a very good program for identifying your devices when you need to find driver after reformatting. Benchmark of course.
It gets information for everything.
Is there anyway to physically short the smart chip in order to reset the data?

 

Maybe reading up on the battery's themselves would help you just go to wikipedia for an hour or so does wonders for the mind

 

You said you have 11% wear level.... and you waited 3hrs for it to shutdown itself... Isn't 3 hrs the typical running time of a 3cell? Anyway try leaving the AAO on standby until it really drains the battery. That should really reset it to 0, then charge to full capacity. See if it helps.

 

does BIOS 3305 help with the calibration?
ok, I will try that.
I am sorry, my battery was at 67% when I was talking to you guys.

 

ok, after I tried to recalibrate, the wear level turned to 12%. WTF?!?!
more help here?

 

Sorry the ignorance, but what is "recalibrating" the battery about ?

 

Recalibrating is basically to let the battery re-learn its own chip.
So if I could only use 4 hours out of my battery, I might be able to use 6 hours out of it afterwards.

 

oh great, now it is 13% wear level, anyone?

 

Every time you fully discharge the battery, it loses maximum capacity. You're not going to be able to fix that, because the LiIon cells themselves degrade.
That's likely what it means by wear level. (Stock Max - Current Max) / Stock Max; and the stock maximum capacity is 2200 mAh.
You're not going to be able to fix it unless you get a new battery.
Why would you want to stick your battery into reporting that, for example, 1900 mAh is its stock maximum?
Either way, it's not going to change battery life.

 

it changes its maximum charge, if only I could use a program and change its eeprom inside the battery, then it will be all good...

 

All recalibrating does is ensure the battery's controller has correct information on the charge state and maximum capacity of the cells, it does this when you do a full discharge and charge cycle, however this is bad for lithium-ion cells, so you shouldn't do it often. It will not increase the capacity you have available. If you could reprogram the eeprom inside the battery all the result would be is it not displaying the correct charge with the risk of the battery running out of power when it thinks it still has some left.

 

That's pretty true, but 13% wear level in 1.5 months? that seems a bit much for 1.5 months. I only discharge every 1 month.
So, I see that I might be getting a defective battery.
lets calculate this, in one year my battery will be fully dead.... not even a year. I seriously think something is going awfully wrong with my battery.

 

Li ion batteries have limited charge cycles. I believe its 300 [or] more. Only recalibrate when necessary... and try not to drain the battery so deeply.

Please read: http://batteryuniversity.com/parttwo.htm and
http://www.apple.com/batteries explains what ONE "charge cycle" is.

The more you try to calibrate that battery, the more you're killing it!!!!!!!!
Say if you ONLY NEEDED 30% of your batt life PER DAY, only use that 30% and fully recharge it. Don't drain it to 0 and then charge. It stresses out the battery A LOT. recharge often as early as possible, or drain it to 40-80% and throw it somewhere cold for long term storage.

 

Li-ions prefer constant cycling around 40-50% charge. Basically you charge up to 80%, discharge down to 40% and repeat. That will preserve the battery the best although it makes the computer less useful.

 

I have read elsewhere as well that charging Li-ion batteries to 100% reduces their lifespan. Are there utilities for windows that automatically stop the battery charging before it is full?

 

I don't think there are any general applications out there that work for every laptop. Individual manufacturers may/may not have power management software that allows you to set charge points for the battery. I haven't tried putting my Thinkpad's power management software on my Acer but I doubt it would work properly since most of that stuff is proprietary.
