Hi, I am Mark Neal From San Francisco in the United States. I'm the founder of BATTERY MAN GUIDE since last December in 2017. My team from Philippines and i have been working very hard to write lot of articles about "product reviews" and "how to guide" on batteries we believe they will help for what you look for! You may sometimes find some incorrect grammars and less engagement dialogue but we will improve our contents continuously along the way. To be honest, we are still not well established battery website, but we are trying to become an authority in this industry in the future by providing valuable information for our readers. With that being said, thank you for visiting at BATTERY MAN GUIDE and we are looking forward to having a great relationship with you!
