ONICD Batteries These are the oldest type of cobalt ontario copyright cell phone battery and as is the case with the laptop computer are less reliable than the newer types.
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.
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.
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.
Now you want to discharge the battery. If you disable the hibernation setting or anything else that might make the computer go into power saving mode, it would be better. Let the computer run until it shuts down due to loss of battery power, then turn it back on.
For jobs where the batteries are required to be light weight as well as being reusable, then lithium batteries are ideal. But if a battery is needed to be very reliable or to remain unused for a long time then they might not be the right batteries for it.
