New Laptop Battery Care

[shea851]

Hi, I recently bought a laptop, about a week ago.

Right now, using Everest Ultimate Edition, it's showing that my battery designed capacity is 64800 mWh. The fully charged capacity is 34790 mWh. and my wear level on the battery is 46%.

When I first got my laptop, I plugged it in and let it fully charge the battery. I left it plugged in a few days and then took it off the power and as a test played some CoD4 to test how long the battery would last while gaming. I played until the laptop ran out of juice and shut off. I then fully charged it again, powered the laptop off, removed the battery and set it aside for a few days using only the power adapter (in hopes to create less wear/tear on my battery).

How is it that my battery is this F'd this quickly? Is it something I did? I wonder if my warranty would cover this.

Plus tell me that having a fully charged battery in the laptop is effectively the same as removing the battery.
I can't see why a laptop would be designed to put unnecessary wear on the battery.

I also have a brand new laptop and am interested to know the best way to protect my battery from wear.

My numbers after 3 days of use:
Wear Level 6 %
Designed Capacity 57720 mWh
Fully Charged Capacity 53780 mWh

Edit: I've done a little reading and now have this question. Is it okay to remove the battery and place it inside a refrigerator(inside a ziplock bag or something)?

I really like how Vista lets you decide on when to recharge your battery (like to charge my battery between 20 and 40 percent). When I had to send my computer in for repair I have my battery charged to about 40% and put it in a ziplock bag with as much air out of it as I can then place it in the refrigerator. My battery is about 15 months old and still has 66.32 Wh with a battery designed for 66.24 Wh. I hope to keep 4 to 5 hours of battery use until I am done with school next year.

There are many helps online on how to keep your battery in good condition. In summary keep your battery cool, avoid storing at full capacity (store at ~40%), store in cool dry location (never hot), do not charge too often (try to charge around 40% or below), cycle your battery about monthly or when needed (full discharge then full recharge), most batteries will last 2 to 3 years if taken care of properly. Use your power management wisely.
