It isn't always possible to be near an outlet to keep a charger running. A laptop is supposed to be portable. But a user may still need to be on their computer more than just 2 or 3 hours their batteries allow them. That can turn into a real problem if the person can't keep their computer running because edison battery its battery just died.
There are several types of battery in use at the present time and each must be treated differently. There are Nickel-Cadmium (Ni-Cad), Nickel-Metal Hydride (NiMH) and Lithium-ion. Ni-Cad is old technology and hence only found in ancient handsets, so I will not be covering them in this article. NiMH batteries perform much better than Ni-Cad, typically giving 30% more talk time, but Lithium are thinner and give even higher performance. I will be concentrating on lithium facts-ion as it is the most used modern mobile phone battery to date. Check which type of battery your phone has before following any of the following.
In my own personal battle with alcohol, drugs (copyright) and manic depression, I had a number of showdowns with the supernatural, most of which horrified me. I believe it was hard evidence that something demonic was happening. After much research, I came to the conclusion that something certifiably demonic was at the source of my battles with mental illness and addictions.
The mating lithium bettery stock process between the two engines can be in series or in parallel. When the two powertrains are mated in series, only one of the motors controls the cars movement. The other one simply assists the first, dominant engine. This occurs most often in mild or assist hybrids. The Saturn Vue Green Line Belt Alternator System (BAS) is a good example. The concept vehicle named the Volt from GM is another good example of a series (but not a mild) hybrid.
The incredible Fisher Karma can't miss from my list. This car includes a gas engine used to recharge the battery as well as an electric motor for that powertrain. The Karma was created by Henrik Fisher and boasts a 300 mile range. It may turn from zero to 60 mph in less than 6 seconds and may reach a maximum speed of 125 mph. The very first 50 miles are impelled by using a fully-charged battery and after that the gasoline engine turns on a generator which charges the lithium-ion battery. Interested? Then you should know that its cost goes up to $110,000.
The bottom line, be gentle to your lithium-ion batteries. If you excessively charge the battery, with high voltages, and heavy load conditions, it will shorten your battery's life. It's best to charge at a slower rate.
