Many of our everyday electronic devices require batteries in order to function. We need our watches, digital cameras, music players and gaming devices to be mobile, so plugging them in to a wall outlet isn't an option. Regular batteries aren't always an option either, as many consumer electronics require more sophisticated batteries.
Typically, the technology used to make electronics batteries is more advanced than that used to make batteries that are seen as fit for everyday or household use. However, precisely how advanced the technology is varies from device to device. Newer electronics and upgraded versions of older electronics will usually function best if powered by batteries designed to function in that device. In other cases, the size of the device dictates the need for special batteries made to accommodate it.
There are many different types of electronics batteries. One type is the button or coin cell battery (also referred to as the watch battery). The button battery is a single cell battery that can be used with hearing aids and small calculators. Another type of battery specifically designed for electronics is the photo battery. Photo batteries are lithium batteries that function well in digital cameras. One of the reasons that digital cameras need special batteries is because of the LCD screens they use. Everyday batteries simply don't provide enough power to illuminate an LCD screen for an extended period of time. There are also other general high-tech batteries that are specially designed to power handheld music and gaming electronics.
To get the most out of your electronics batteries, you should use them only in the devices for which they are designed. If you have rechargeable electronics batteries, you should charge them only when they are completely out of power.
When shopping for electronics batteries, look for batteries that cost a little more than the standard household non-rechargeable alkaline battery. In many cases, the battery packages will tell you if they are customized for electronics performance, in addition to specifying the electronics they are best for. If you are searching for a button or coin cell or watch battery, you should take the dead battery with you so you know which kind you need to buy.
