With the rapid technological advances of modern America, the laptop battery charger has become an indispensable device in almost every household. Many people need laptops for work or school, and since most batteries can withstand only a few hours of continual use, a charger is absolutely necessary when your laptop cord cannot be used or you need to be able to move your laptop.
Every laptop is different; therefore, not every laptop can use the same charger. Some chargers can only be used for a certain brand of laptop, while a growing number of them are compatible with as many as nine or ten brands. Whichever way you choose to go, make sure the charger carries your laptop brand. Another extremely crucial consideration is the voltage of the laptop battery. If the voltages do no match you run the risk of undercharging the battery when the volts are too low; and the battery could be severely damaged or even catch fire if the voltage is too high. Always be sure that the voltage on the battery and charger are the same within two or three numbers.
More and more stores are beginning to sell universal battery chargers. These are especially convenient for people with several laptops, cellular phones, and MP3 players or iPods. They generally have a plug or plugs for laptop tips and a USB port on one end and a wall socket plug on the other. Most universal chargers you will find have up to nine laptop tips for different brands and often a USB adapter for many cell phones. They will usually run from $50 to $100, depending on how many laptop brands and other devices it can support. Anything over $100 is probably not worth the money for most people.
Along with battery charging, there are ways to make a battery last. Always turn off the laptop when it is not in use. Screen brightness can be a battery drain, as well as programs that require a lot of memory. Any programs that are not being used should not be on your laptop. To avoid the memory affect – the idea that a battery loses charge capability if it is recharged unnecessarily – do not charge your battery unless it is needed, or consider using a lithium-ion battery if your laptop does not already have one. By preserving the life of your battery, you help prolong the life of the charger as well.
Laptop battery charger shopping does not have to be a difficult process. Decide ahead of time what is right for you, if you have to; write down the brand and voltage of your battery or batteries to make sure your new charger will match. Set aside the amount of money you want to spend based on whether or you want a universal charger or a one or two brand charger, which you can usually find for under $30. Finally, take care of the battery and charger so you will not have to buy another one soon.
