Long Lasting Batteries

Yesterday, as I was using the laptop of my friend she told me first to check if the battery is still full and so I did. I notice that there was a sign on the battery icon which means that it better to replace the battery. I ask my friend about it and she told me she does not know what does it mean. So I explained to her what was it all about. She was worried since her laptop was already out of warranty. I really suggest to her to replace her battery with a universal battery charger as soon as possible. Most laptop  batteries hold a charge for one to two hours or more before they have to be plugged in and recharged. There are also  extended life laptop batteries available for people who want laptop batteries that have the potential to last for four to six hours on a single charge. But no matter what type of laptop batteries we use, it is important to remember that all rechargeable batteries lose their ability to hold a charge overtime. This is why there are also replacement laptop batteries available for our convenience.
