An electrical battery is one or more electrochemical cells that convert stored chemical energy into electrical energy. Since the invention of the first battery (or "voltaic pile") in 1800 by Alessandro Volta, batteries have become a common power source for many household and industrial applications. According to a 2005 estimate, the worldwide battery industry generates US$48 billion in sales each year, with 6% annual growth. There are two types of batteries: primary batteries (disposable batteries), which are designed to be used once and discarded, and secondary batteries (rechargeable batteries), which are designed to be recharged and used multiple times. Miniature cells are used to power devices such as hearing aids and wristwatches; larger batteries provide standby power for telephone exchanges or computer data centers.
Not good one thing
The app is pretty cool, I think that it is one of the best between battery apps, but i can not use all functions, for that I have to download one app which I don't want on my device. I don't understand, why I must download app, which I need not ? This is totally bulsh...t

I tried it for my first time let it sit for about seconds, then it opened an ad then safari, then iTunes, then the App Store. It also didn't have the right percentage
BOOOO!!!!!
Whenever I try to open it, it crashes!😡 I've tried to reinstall the app a few times, but it's the same thing: a black screen and then a crash. If you fix this, maybe I'll rate higher.
