First on my small list may be the Coda electric car available with a 4 seats capacity and powered by a 728 cell cobalt ontario canada-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.
Nonetheless, the Volt is not something in GM's immediate plans. The idea for the Volt would require that a cost efficient 400-lb lithium-ion battery be found. lithium facts-ion batteries of this size are not currently available. Further advances in battery technology would be required to allow GM to consider making the Volt a production car. These are enhancements that could occur in as little as a year, or as many as 20 years. GM has stated that they feel the technology is almost there, yet a vehicle like this is probably about a decade away.
Even the best solution has internal resistance, which it discharges through over time, thus that optimal 40% capacity drips away. Another thing Lithium-Ion cells absolutely loathe apart from heat and being overcharged is being fully discharged.
Avoid using replacement that has been on lithium bettery stock for a while. During storage the battery can lose much of its capacity through internal resistance, which damages it and lowers the maximum capacity.
You have more power to perform work better and faster such as drilling and screwing than the smaller model. Once I used the 18v model I found that I prefer to use it more often because it gives me more power to complete the same task with less effort. At the end of the day it is better and faster, productivity counts.
With any battery, every time you charge it, it loses a bit of its performance and power. Over time, that battery will die, and after you give it a proper funeral, you'll have to change it. The same is true with your iPOD. Eventually, you will have to replace the iPOD battery. You can either change the iPOD battery itself or purchase a new iPOD Nano . But, because your iPOD battery is a lithium-ion beast, you won't need to worry about that for a while!
