subject: lithium ion are high-energy, weight, rechargeable batteries [print this page] whether the general use of lithium ion (Li-ion) or lithium polymer (Li Po) battery chemistry. These battery types are high-energy, weight, rechargeable batteries have been proven technically and economically feasible. They are also more environmentally friendly, the old battery chemistry.
External laptop battery, often called universal notebook computer batteries because they have multiple functions, in essence, offering a wide range of notebook PCs equipped. In this regard, the main characteristics of a variable voltage output, power adapter, a variety.
Should be noted that the voltage requirements of the computer in the choice of external laptop batteries. While these batteries usually provide some discrete time interval of voltage, you must ensure that the available output voltage in a + / -1 the requirements of your laptop is volts. However, it is common to find 3-5 different voltage output, the same battery of these universal power supply voltage battery can be used for different Batterylaptop battery requirements, the number of different notebook computers.
In addition to voltage requirements, to ensure that the power adapter for your computer's power port is not included in the battery itself, or available as an option. Terminated with these batteries need an adapter to place the plug with the charger. These are called barrel adapter, because they are a small microphone on the charger plug slides in many cases, there is a cylinder.
Key in a choice of optional battery specification is its energy will be held, because it stores the charge, will provide power to operate the laptop. While many laptop computer batteries mA, ampere-hour (mAh) battery level requirement to indicate the battery's storage capacity, watt-hour (WHR) is a better evaluation of the norm, because it is an absolute value is independent Comparison of the battery voltage.
The laptop battery to provide the general public consumer version of the evaluation range of 74-142 WHR. This will usually provide sufficient power to operate the notebook computer increased by 5 to 12 hours depending on battery capacity and the computer's power requirements. These batteries will be for the average consumer from a 3-pound, and in half. The commercial version of these batteries hip ratio is usually in the 200-500 range to maximize available to use your computer's operating as a remote power source notebook. dell 700m battery dell C1295 battery Dell U4873 Battery Dell Latitude C600 battery
Although not so much concern for safety, ensures the battery is equally important group of amps is equal to or exceed the notebook computer's amp demands or face not Tigongdianyuan laptop. This specification is the most easy to find on the charger, batteries and notebook computers with OEM labels to find.
Most of the time these external laptop battery can charge the internal battery. However, this is dependent on the computer and the circuit may not always the case. Some of these cells and their associated provide a laptop computer charger automatic voltage detection, and provides LED power display to indicate battery charge level outside. Some of these batteries required PC's power adapter to use battery energy, but most are equipped with their own battery charger. In addition, the number of charger will run in the 120 and 240 volts to an international travel and easy to use. Optional converters can also be collected from the 12-volt DC power supply, such as car batteries, these batteries.

An obvious advantage of many of the capacity of external batteries to power other equipment, such as: PDA, iPod and digital cameras, portable DVD players and cell phones. USB power cable are available a number of the output of 5 volts in order to promote the work of the external battery.
