A itunes gift card AA battery is like a lifeline to many of us who use a lot of mobile electronic devices, and their incarnations are many. The invention of a device came from the explosion of mobile technology, where people were more ‘on the go’ then they were ever before. The forms of devices also shot up and over the roof in terms of their innovation and application. But of course, they all fell under the same rules of the universe in which it is invented in. Like all devices, especially the ones which are more complicated and advanced, require much more power than the normal, back dated ones.
Their capacities increased and their need for power increased as well, so manufacturers saw a gap in the market. Sure, many of these devices, like hand phones and MP3 players, came with their own rechargeable batteries, but most of the time, it was a single unit that required continuous recharge on its own. That left no space for backup spare power, and when you do need one, you almost always have to buy one from the company that sold you the product in the first place. This means that the cost will be prohibitive and you have only one source if any complications do arise.
This was the trend for a while, and aa batteries still did not come into the forefront. But the thing is, even when manufacturers did decide to replace their batteries and streamline some of their products to be used by normal aa batteries, the rechargeable ones were slowly taking over a storm of their own. Devices which relied heavily on batteries, like remote control units, toys, some work tools, mobile devices, handhelds now saw their operation costs cut down by a lot. Buying new batteries all the time sometime could mean a hole in the pocket, especially with the rising prices and having rechargeable ones means that there are a lot of savings when it comes to using mobile devices.
Power wise, many have said that the power of a rechargeable battery will slowly decay over time, and over the many times that it gets recharged. True, but this is at an obvious advantage of having the same power and durability levels as you would have with any normal aa battery. And the ‘problem’ with the power decaying has been carefully addressed as technology increases and as more research has gone into metals and the use of conductors. Also, the reliability of a rechargeable battery is pretty good.
In terms of longevity and use, there have been very little complaints about the reliability. The good thing about rechargeable aa batteries, is that you can have ownership over a few, so that if one fails, you will have another set to spare when needed. This means that you wont need to stop listening to your favourite song or even able to finish your game on your ride home, or wherever it is you are going.
