What are your driving habits? What are the longest distances you will be traveling? When driving a pure electric vehicle; if the battery runs out completely with no charging stations available you will be stranded. With the long charge times, it will take some time to make the vehicle usable again. This is where the extended range kobalt minen Volt becomes more practical. Filling up the gas tank is faster than waiting for the battery to charge.
Power cords - Again, in my opinion, they are poor quality and might damage your electronics. Duct tape sand paper painter's tape lithium facts and bungee cords are good though.
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.
For this cordless drill comparison I decided that the chemical properties weren't important to me. What mattered was why an Li-ion battery may be better than a nicad battery. My drill comparison came up with 2 major reasons. Li-ion batteries weight is about half that of a nicad battery. In other words when you hold a 18 volt lithium bettery stock ion powered cordless drill driver over your head you will notice a major difference in the weight over that of a 18 volt nicad drill driver.
On February 25, 1998, I went into a cold and deserted New York City area park and prayed for deliverance from alcohol, drugs and mental illness. I cried and fell on my face with outstretched arms begging for my freedom. In the invisible realm I sensed a heaviness being lifted, I felt bondages being broken, chains snapping and a sense of release. I walked out of that park a free woman.
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!
