Laptop computers are increasingly becoming the primary (or only) computer of many people. This is because in addition to the size, cost and portability advantages they have always had over desktop models, many of them now are powerful enough to do the kind of work that only the desktops could do well in the past. However, laptops still have some weaknesses, and one of the primary ones is that if you are using battery power, the amount of time you can do work on your laptop before having to recharge the battery can be surprisingly short.
Luckily, there are some batteries that are considerably better than the default ones that come with your laptop. Following is a guide to purchasing the best laptop battery for your needs.
When searching for a battery, there are other concerns besides how long you can go on one charge. The other things to consider are how many times you can recharge the battery before it needs to be replaced, how hot the battery gets, the price, the build quality, and of course, whether the battery will work for your particular computer. The manufacturers of computers will tell you that the best laptop battery not made by their own company is an “OEM” battery. OEM is the acronym for “original equipment manufacturer” and means that the battery maker has been licensed by the computer maker to make the battery and to sell it under the computer maker’s brand name.
However, there are generic batteries that will work fine, and they are usually less expensive than branded batteries. Almost all batteries for laptops are the lithium-ion type. To get the best battery laptop battery for your computer, try a search online using a search term that uses the exact phrase “battery for”, in quotes, along with the model name and number.
For example, your search could look like this: “battery for Inspiron 1525″. The first few pages of results will include both OEM and non-OEM batteries. If being able to use a battery for a long time on one charge is the main thing you are looking for, the best laptop battery will go for about six hours when new. This time is measured in milliAmp hours or mAh. Look for a battery that is rated at least 7000mAh.
If you want one that is best for long life before needing a replacement, three years is about the longest life you will find. Keep in mind that how long it lasts depends very much on how you use it.
The best laptop battery is one that is used properly. If you clean its contacts every few months, use a charged battery at least every few weeks, and do not let it discharge all the way, your battery will have a longer life. It will also go longer on a single charge if you use your computer efficiently, by doing such things as adding RAM, defragging often, and not having many programs running at once.
