Battery Problem?? Help please

So I've had the laptop in my sig for about 9 months now. I used the battery on it for the first 3 months but after that I stopped. I left it in the carrying case and today I put it back in. So I notice I have 40% left...goes down to 23% after a good amount of use. So I decide I'm going to charge it well its been about an hour and a half and its stuck at 46% it hasn't been moving since then. Is the battery life cut in half already? Or is something wrong with my laptop?

 

Probably needs to be re calibrated.

Look for batterycare on these forums or via google.

 

find battery care in my signature below.

if it has indeed lost its charge in 9 months it should be replaced under warranty but this is where the small pring comes in. some companys will only cover the battery for either 6 months or a year.

ive had 2 batterys die on me from 2 different laptops. i now always remove my battery when it wont be used for long periods of time and and after 3 years they still have 98%

but of course there are lots on here that say thats rubbish and leaving it connected wont shorten its life.
heat is a batterys worst enemy.

 

So what you saying is you remove the battery when your laptop is connected to the power adapter. Sounds good and would even make the laptop lighter if you are using it on your lap

 

yup.
theres been a lot of chat for and against this. all i know is its worked for me after having 2 batterys die.
4 year old m860tu battery always left connected and had only 25% charge after 11 months. replaced and i remove it with 40% charge when i know i wont be using it for long periods of time. after 4 years it still has 98% charge.
fujitsu battery died after 2 years with 0% just about to get it changed as i managed with just mains.

heat is a batterys worst enemy.
you will get lots saying it wont harm it at all leaving it connected but im only going by what i know.

 

Still nothing now that I calibrated it let it run all the way down, when I charge it it stops at 12% now and does go up.

 

Let the battery completely discharge. To do this, you'll need to tell Windows to eliminate a reserve battery charge (Defaults to 7%)

Control Panel\Power Options\Change Plan Settings\Change Advanced Power Settings Scroll down and look for Battery. You'll want to adjust these settings to tell windows not to do anything when your battery gets low and to not have a reserve battery.

Let your computer power down.

Remove your battery and leave it out for a week.

Plug it back in.

This will completely discharge the battery and reset the memory in there.

 

I don't claim to be more knowledgable than the fellows here, but a simple wiki of Li-ion batteries which laptops use will tell you that once you leave a battery completely discharged it slowly ruins the battery. The ideal way is to keep it at half-charge and re-charge to half every couple of weeks to maintain cell integrity. Some people insulate it well and leave it in the fridge (there's a chance of condensation of course) for the period. Once you leave it for months upon months depending on how lucky you are you will ruin the battery.

Google maintaining battery life unplugged. Leaving it plugged the whole time is bad of course as well. They are designed with a certain number of complete charging cycles my old laptop's battery was designed for 650 cycles before it gives out.

Once that happens I'm not sure any software solution or "memory reset" will fix those cells on the hardware level.
