If you were to look at most of your high end electrical devices such as laptop, personal digital assistant, cell phone, MP3 player etc, most probably it will be powered by a lithium based battery.
I could easily have spent a fortune replacing the motherboard, the memory, the processor etc when it all came down to 2 dollar battery. What's more is these batteries are easy to get. What you need is a CR2032 available at most hardware stores like home depot and I've even seen them sold in Safeways. Of course every reputable computer lithium stock store should stock them. Just check to make sure that your PC uses a CR2032 before you go to the shops!
If you work for long hours on your laptop then the temperature inside the laptop can rise which affects the battery-life. This occurs due to cell oxidation inside the battery and this plays lithium facts a major factor in reducing the lifespan of the laptop battery.
There are some concerns when it comes to these high powered batteries and how good they are for the environment. But all hybrid batteries are set to be recycled (Toyota has a $200 bounty on each battery pack), and so unlike some lead batteries from conventional cars, they shouldn't end up in landfills.
But that means that laptops need to have bigger batteries and bigger batteries mean bigger size. Laptops won't be portable and convenient to carry in this case. That's the reason why laptops have compact batteries that gives it a sleek look. But these batteries don't lithium bettery stock have good battery-life.
For any new laptop, the battery usually comes empty. It's advisable to charge at least 4 hours non-stop on the first charging as it can prolong the lifespan of the battery. Also during the first charging, it is not advisable to use the laptop battery at all.

So the number one thing that you can do to extend the life of any of the newer lithium batteries is always take it out if you are running on DC power to lessen the heat impact. Whenever buying any replacement battery, always check the manufacture date and try to find the newest one available.
