Good product, great company
I bought these batteries as part of a complete solar power system to run the water pump on my fountain. They are exactly as advertised. Better yet, Mr. Solar as a company has been great. I've called a few times with questions - some dumb, some tricky. The people at Mr. Solar are busy, but I always get a call back and they work with me to troubleshoot my system. They are respectful of my intelligence, look things up instead of guessing, and have 100% success at helping me solve the problem.
