Now yes edison battery it depends on how you're using it. But the Apple creators say it will play movies solidly for 10 hours for example before the iPad battery says "feed me".
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.
OLithium Ion (Li-Ion) - This was the latest battery technology before lithium polymer. They have a higher power density than NiMh and NiCd batteries. Li-Ion batteries generally come standard with most phones. For most people, this battery technology represents the best combination of size, capacity, and value. These types of batteries don't suffer from the poor memory effect and can be recharged anytime.
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.
As mentioned earlier, there are different types of batteries. You can choose a lithium ion battery if your primary source is electric power supply, but you do switch from fixed power to a battery on a regular basis. A Nickel based battery is preferable if you use a battery as your primary source.
Last, but not the least on my list is the $109,000 Tesla Roadster, a pretty hot sports car. The Roadster is an extremely fast electric car in a position to go from zero to 60 mph in just 3.9 seconds and, moreover, it may run up to 245 miles on a single charge. It is made from carbon fibre and also the power train features a custom microprocessor-controlled lithium-ion battery. The inside is incredible and features cruise control, power windows and door locks, ac, leather, touch screen featuring GPS, HD Radio, Bluetooth and several other gadgets.
