Battery

What is the best brand, wattage and tips for working on laptop computers? I have several laptops that need repair, they vary in degree of disrepair and need to know the best kind and most economical solder iron to use for this project, I am on a very limited budget, so price is a factor. I have tried Radio Hack and they break within a few weeks.

Are Toshiba laptops good? Are they reliable? I’m searching for a good laptop and I would like to know. Thanks in advance!

The battery on my cell phone that i’ve had for approximately 2 years lasts about 10 minutes when fully charged. My last resort is buying a new battery. What can I do to make the battery life longer? It is a lithium ion battery in a kyocera cell phone.

If i do have to buy a new battery? How much would it cost me or would it be cheaper to just buy a new phone?
Added at 9:37- Can I freeze it? Would it damage it? How long should I freeze it for?
I have the backlight at 5 sec. I even disabled the backlighting for awhile but I had to turn it back on, I couldnt see anything.
Its a prepaid cell phone… no contracts and I always have the charger plugged in
