The most common chemistries used in laptop batteries are:

NiCad (Nickel Cadmium) – This is the oldest technology and is the least commonly used nowadays. NiCad batteries are prone to the “Memory effect” and are heavier than the newer technologies. NiCad is not environmentally friendly chemistry as it contains heavy metals, which cannot be disposed of in landfill sites. Most manufacturers have stopped producing batteries of this type chemistry. As an end user it will be increasingly difficult to source these batteries. The best alternative is external battery packs. This is an external battery, with run times of up-to 10hours and is compatible with most manufacturers.

NiMH (Nickel Metal Hydride) – These batteries are less likely to be prone to the memory effect and have a much better power to weight ratio than NiCad. This is a commonly used chemistry. These batteries are also being phased out by most manufacturers. However, many have lithium-ion versions that are compatible. Always consult the manufacturer or a reputable laptop battery supplier.

Li-Ion (Lithium Ion) – This is becoming the dominant technology due to its excellent power to weight ratio. Such considerations are becoming more important as mobile devices become smaller and lighter and battery weight becomes significant. Another plus point for Li-Ion is that it doesn’t suffer the memory effect at all. These batteries do have a tendency to lose charge quickly towards the end of their effective life span. If this starts to happen the battery must be replaced.

These three technologies are quite different in the way they charge and therefore should not be substituted unless the device has been designed to take different chemistries. The owner’s manual will describe which batteries are suitable. Lithium Ion laptop batteries are available at ComputerBatteries.co.uk

Laptop Battery Capacity

Laptop batteries are rated by, Voltage (V) and Milliamp-hours (mAh). Voltage is the rate at which energy is drawn from the battery and Milliamp-hours represents the capacity of the battery. The Milliamp-hour rating corresponds to the run time of the battery. A battery with a high Milliamp-hour rating, has a relatively longer run time than a battery with a low Milliamp-hour rating.

Batteries with different Milliamp-hours can be used on the same laptop provided the voltage rating is the same. The voltage rating has to match that of the original battery or as recommended by the computer manual. Using a battery with a different voltage setting can seriously damage the laptop. The power ratings of most compatible/replacement batteries are higher than the original manufacturers’ batteries. This will not damage your laptop, in fact, it simply means that these batteries in many cases last longer than original manufacturers’ batteries. Ask the experts like PowerUp on compatible replacement laptop batteries.

The run time of a laptop battery will vary on individual notebook computers, based on the applications being used (i.e. high graphics, games), the number of times something is saved or retrieved from the hard drive and/or CD Rom drive, the memory of notebook, and chemistry and capacity of the battery. A ‘realistic’ average run-time for a battery is 1.5 to 3 hours. Using devices like a wireless adapter on the laptop also drains the battery considerably.

The life of a battery under normal use is around 500 to 900 charge-discharge cycles. This is about one and a half to three years of battery life for the average user. As the rechargeable battery begins to fail, the running time of the battery begins to decline. See the Laptop Battery & AC Adapter Information page for advice from PowerUP.

Laptop Battery Care

Most laptop batteries when purchased are sent out in a discharged state. The laptop batteries require to be “run them in” to achieve maximum performance and the best service life. Simply insert the battery into your laptop and allow it to charge fully and then, fully discharge your battery (i.e. run your laptop using battery power until it switches off) then fully charge your battery once again.

It is possible that when you first put the new battery into your laptop it will show it is fully charged almost straight away, but it doesn’t power the laptop for very long. This does not mean the battery is faulty, simply take out and reinsert the battery, fully charge it once again and this should solve the problem.

It may take some time for certain laptops to recognize new batteries and you may have to run a calibration program that you can access through the control panel on your laptop. If in any doubt please consult your user’s manual for your laptop.

Make sure that you fully discharge your battery from time to time, as this will prolong the useful service life of the battery. If you are not going to use the battery for some time (perhaps a month or more), remove it from your laptop in a fully charged state and store it in a cool dry place away from sources of heat and light.

Listed below are tips to ensure optimal battery life:

* Use the AC adapter whenever possible. * Set the Windows Power Management settings to maximum savings. * Lower the brightness setting on the screen backlight. * Disconnect any unused devices (e.g., modems) when not needed. * Use power management freeware like Power Center 2.12. * Disable Auto Insert Notification on the CD-ROM. * Turn off Autosave features. * Disable automatic formatters, spell checkers, and autorecalculate features. * Use disk caching programs such as Norton Utilities to lower disk access time. * Add RAM to lower disk access time. * If you have a backup battery, use it in rotation with the current battery. * Use the Suspend or Hibernate feature when taking a break. * Fully drain and recharge the battery every couple of months. * Minimize the number of programs running at the same time. * Use smaller programs when possible (e.g., WordPad versus Word). * Minimize game play and DVD viewing.

Something named “backlinks” is especially significant in the world of search engine optimization (SEO). Even though you may be new to internet marketing (IM) or may only have just launched your first website, this is a critical topic. Backlinks are utterly essential for any user seeking significant Google search engine rankings.

Internet marketing uses two major strategies: paid advertising procured through various services, including AdWords or AdBrite, or search engine optimization. SEO uses backlinks in the quest for exceptional placement on keyword search results, with the goal of appearing first or very near the top of any Google search. Thus it is very important to utilize this strategy, either through learning and applying it or finding a reliable server to do this work.

Most internet users are quite familiar with hyperlinks: these are typically underlined bits of text that can take the user to another website. Simply clicking on the hyperlink will deliver the user to the new site. Simply put, a backlink takes users back to your own site, creating and generating more traffic to your site. This increased traffic can be important, and the backlinks are used in other ways by search engines, notably Google, in ranking your site.

Remember that Google holds the lion’s share of the search engine market. Although Bing and Yahoo rank keyword search results using factors intrinsic to your own website, they represent less than a quarter of the market. And it is Google that uses backlinks, hyperlinks to your own website found elsewhere on the web, to rank the significance of your site.

So, here is how Google uses backlinks: remember that these backlinks are placed on various sites on the web. Google finds them because the bits of text turn up in the keyword searches users enter. The words that are used in the backlinks are called anchor texts. Google weighs the significance, or authority, of where the backlinks are located in ranking the importance of your website.

So, suppose you have a start-up website based business and you would like backlinks to create and build a good search engine ranking. In early internet etiquette, you would have approached webmasters directly, requesting placement of a link at their site and offering to do likewise for them.
