Lithium ion batteries are a great thing to buy if you want to cut your battery costs. They are not a new invention, they were first made in 1912. there are a huge amount to different batteries available from the smallest ones to some really big industrial type. For the amount of power that they are able to store. Most other types of power storage units are much bigger than Lithium ion batteries. The other main batteries that could be used for the same thing are much heavier. Lithium ion batteries high capacity is due to the material that they are made of. Lithium ion batteries do not suffer from a high discharge rate and are very practical for storing energy efficiently as well.
Another electric car may be the Ford Focus EV which is available in a limited edition. The drive train from the Ford is manufactured by Magna International. Consequently, the Focus may have one hundred mile range and you will be designed with lithium-ion batteries. This car is going to be sold for a price tag around $30,000.
Why is this important? If you have a relatively new PC the only problem you will get are error messages relating to the clock on start up. No big deal. If your PC is older then a low battery could be a nightmare. I had a PC which once cobalt mine every few months refused to boot. Rather than take the PC in for repair or start replacing parts myself the first thing I did was look at the BIOS settings. It was soon obvious that the BIOS settings were corrupt (wrong bus speed). I put a volt meter on the battery and sure enough it was reading 2.2 volts.
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.
Another thing to remember is not to store those batteries in the charger as well. This will draw energy away too, and cause your battery to die off sooner than you expect. Keep it away from high heat or extreme coldness. Heat tends to cause damage to your Lithium battery stocks while exposing it to low temperatures over a period of time will draw its charging capacity.
ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium mines Ontario batteries. These should be cycled once in a while for optimum performance.
Memory effect will reduce the life of a battery. Modern Lithium-ion batteries do not suffer from memory effect, although it does occur in Nickel-Metal Hydride (NiMH) units when charged from levels other than 0% of battery capacity. If the (NiMH) unit was fully charged when initially at say 20% capacity, the resulting available capacity would only be 80% of the factory original. Of course every time you charged the battery, the total available capacity would reduce and eventually your mobile phone would prove to be increasingly useless. Nearly all new electronic devices are now powered by Lithium batteries. You should always condition your (NiMH) battery from new.
Step 4 - Connect in the newly bought battery to the board of the iPod (where you unconnected the old battery) and set it on the glue that remained on the hard drive. Make sure that the battery and the wires are set properly so you can actually close the iPod. Snap the cover back together, you'll hear it when it's finished!
