Review on sonnenBatterie by Justin Hines

It's very easy to use, very friendly for everyone who has no knowledge of electricity or electronics stuffs such as me! I'm also impressed with how long it takes for my battery life to decrease after not using it for so many months. We have used Sonnen Batteries when we were living in Japan (we're still there now) - but the price was too high for us back then. So, this is our first time buying batteries from Amazon. When you purchase them from amazon they are cheaper than anywhere else. Also, shipping speed seems to be faster than other sites. They provide all necessary information about their products including warranty period, charging status etc. You can easily check if your device meets requirements before purchasing batteries. As for myself, I've been able to charge my phone multiple times without needing to plug-in again.
