Last year Toshiba recalled about 430,000 laptop batteries because they continued to lose power prematurely. Toshiba also reports that although these batteries were giving problems by losing power, there were no reports of the batteries overheating and there were no reported injuries as a result of the defective batteries.Before the Toshiba recall, Dell and Apple had a battery recall because Sony had produced a defective batch of batteries. These batteries were known to overheat and some of them even produced fires. EZ Battery Reconditioning Review All of these batteries were replaced free of charge but the company did suffer some financial damage as a result of the recall.Rechargeable batteries are rated by manufacturers using voltage, amperage, and sometimes wattage. These ratings are usually listed directly on the battery itself, shown as xV. and xx mAh. Many people notice that the replacement battery they are about to purchase does not match exactly with the voltage and amperage rating of their original battery. Also, several questions often arise about the meaning of "amps", "milliamps", "watts", etc. This article will address some of these questions and provide useful information about replacement batteries.

The volts of a battery refer to an electrical measure of energy potential. They indicate how much electric charge is available to the device from the battery. This number is usually printed directly on the original battery, allowing one to easily compare their original voltage rating with the voltage rating on the replacement battery. Replacement batteries should only be purchased when the voltage is reasonably close to that of the original battery. So, if the original battery is a 3.6 volt, a 3.7 volt replacement battery will work perfectly fine. However, a 7.2 volt battery may cause damage to the device in which it is used."Amps" is an abbreviation of Ampere, a 19th century French scientist. This term refers to the capacity of the battery in terms of runtime. Many batteries use the term "amp hours", but this does not translate directly into actual hours because different devices put different amounts of strain on the battery. Many batteries also use the term "milliamps" of "mAh". This is simply a different way of saying amps, as 1 amp is equal to 1000 mAh. There is significantly more freedom available when choosing a replacement battery in terms of amps. Increasing the amperage in the replacement battery will only increase the amount of time the battery can power the device before it needs to be recharged.
