First on my small list may be the Coda electric car available with a 4 seats capacity and powered by a 728 cell lithium stock-ion phosphate battery. The vehicle includes a range of 90-120 miles and can achieve a maximum speed of 80 mph. It comes with an interesting warranty: 3 years or 36,000 miles. An interesting fact is the battery which equips this car is covered for 8 years/100,000 miles. If you are interested in buying this electric vehicle you should know that the prices are around $37,000.
On top of this wireless fun your iPad comes with Bluetooth EDR ahh yes rubs of chin all round what the heck is all this stuff anyway the upshot of which lithium facts is that you can connect it to accessories like wireless headsets headphones or the Apple Wireless Keyboard if that happens to particularly float your boat.
ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium batteries. These should be cycled once in a while for optimum performance.
Remember how the old batteries would start to wind down before they quit totally? Well, the new Li-ion batteries don't do that. They have the same power when drilling the last screw as they did when drilling the first screw. That seemed amazing to me but I found lithium bettery stock it to be true.
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, in summary, if you have a PC which is showing clock errors or BIOS problems look first at the little 3 volt battery. It could save you a fortune. Happy computing!
