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
for many people the app wouldn't load but for me it did and it was just fine. the only thing I wish they would add is a settings option to personalize it and such but overall it was pretty much perfect. you might as well download it because even if it doesn't load it was free so it is no loss to you :)
If you want to see the battery lvl and not really much else download this. I went ahead and got this and a few other battery apps and this by far is the worst. You get a very plain display that cannot be changed unless you upgrade. There is also adverts that are always there, which is only to be expected with out tha cash.
With Family Sharing set up, up to six family members can use this app.
