Increased capacity in my Rv
This battery was recommended by my social group as a replacement battery for my solar system. They were spot on. Battery life and functionality were increased, easy to install, and the price was much less than the other well known competitors. Size was not an issue it fit my compartment perfectly. I highly recommend. These do go on sale as well so watch the prices.

Customer service
Had a problem with the battery not charging but after contacting the customer service, they guide me through the process and after that everything worked out great. The customer service is excellent and the product. I’m using it for last two weeks now it’s working great thank you for standing behind your products Not like the other brands. The battery itself is heavy duty and they are selling it for a great price

0 volts when I received it
My battery arrived with 0 volts . I'm hoping it will take a charge. It was upside down when I opened box. Hoping it's not bad. Update It won't take a charge. They replaced it and everything works good .
