Until new nano lithium technology comes in later in 2009, mobile phone batteries are still notoriously flaky. Just when you need to make an important call the battery indicator tells you the charge is all but extinct.

Though there are Nickel-cadmium, Nickel metal hydride, etc, after the invention of Lithium-ion battery, because of its efficiency most of the laptop manufacturers are selling it along with their respective laptops.
Let's look at a typical comparison to prove this point. A normal 9.6 volt cordless drill will weigh around 3-1/2 lbs and costs you $35-$150 a piece, depending on the model and brand you choose. If you opt for a higher voltage tool, a 19.2 volt cordless drill would weigh up to ten lbs and costs anywhere from $120-$300 a piece. If you are looking to get more power and torque from a cordless drill, then it may justify the cost of getting a more expensive version. But if you are merely looking to drive screws in your own home, then it would not be a wise move to waste your hard-earned money on a powerful 19.2 volt cordless drilling. It is much harder to use too, because of the additional weight. Under these circumstances, a lighter version would suit you best.

External effects can be a radiator in your room or direct sunlight, or just simply a mind boggling ambient temperature. A Lithium mines Ontario-ion cell loses 20% of its maximum capacity in one year when it's stored on 40 degrees Celsius and full charge. Not too many people have 40 C in their room all year long, but what about internal heat sources? If you use your notebook from AC power, you're keeping it fully charged, which it doesn't fancy, and on about 40C.
The long wires of the LED are taped to the negative and positive sides of the coin battery (+) and (-). Carefully twist the wires, ensuring they won't touch each other, into a right angled position which will enable to the battery to rest flat against the inside cover of a glass jar. Tape the battery in place and screw on the jar.
