If you are among the growing number of mobile executives who are moving from PCs to laptops, is inevitable that soon will face a situation where you have to educate yourself on laptop batteries. And then, at some point, buy them. Here are some basic guidelines:

Brief History of Laptop Batteries: The first type of battery uses chemical nickel-cadmium (NiCd, NiCad), and was very fast to load and was also able to handle large loads. However, these chemicals are highly toxic. The next generation of batteries, Nickel Metal Hydride (NiMH, NiMH), now the use of nickel and other rare earth metals as electrodes and potassium hydroxide as the electrolyte. These are more environmentally friendly than Nickel Metal Hydride, but suffer the memory effect and have a short life. A new type of battery is Lithium Ion (LiIon, Li-Ion) battery power. Despite being more Small and lightweight for NiCd and NiMH batteries, provides the same capacity. In addition, these batteries do not suffer from "memory effect" and have low self-discharge.

Polymer Lithium Battery Lithium ion: This is the last type of battery chemistry. Although this will behave the same way that ions of lithium, there are some important differences. The rechargeable lithium ion polymer uses a thin plastic-like film as the electrolyte, which reduces considerably weight and increased power to weight ratio than most other types. They are used in batteries Universal Laptop. So this is the type of search, when needs a new battery for your laptop.

What are universal batteries?: Most major manufacturers like Sony, Compaq, Fujitsu, Toshiba, Panasonic, Dell, IBM, Lenovo Apple, HP, are providing technology lithium ion batteries. Universal laptop batteries, however, uses the most advanced Lithium Ion Polymer chemicals. A universal battery is simply a larger version of the laptop battery standard, and virtually can power any laptop.

Rechargeable Batteries are universal - the AC adapter and power lead provided by the manufacturer. Moreover, the manufacturer supplies a set of tips that fit the power connector on the laptop. These tips allow intelligent electronics embedded in the battery to supply electricity in the correct voltage.

Another point in favor of universal laptop batteries is that time of continuous use is up to 10 hours at a stretch. (Of course, there are variations depending on the manufacturer and model of universal laptop battery.)

When do I need a new battery?: Not necessarily need a new battery only after the current one is completely exhausted. Some laptop manufacturers offer computers notebooks with expansion slots that accept a variety of peripherals, including a second battery. This second battery can double its life. But, if you are planning to get a lot of work done on that long flight, then it may be time for you to buy a new battery laptop.

Remember: When buying batteries, make sure the manufacturer supplier and are trustworthy. Make sure the supplier or manufacturer full warranty and guarantee. Check the chemistry and size of the universal laptop battery prior to purchase. And provide the supplier with all information on your laptop as the make, model, part number, voltage and current (provided in the manual or the bottom of the laptop) so that the provider may help with the best battery.
