Review on Battery Rejuvenator BLS-36N: Advanced 36v Battery System Desulfator and Life-saver by Dan Reggae

Time will tell how well this works. The idea of using them to extend battery life is a proven one. I just bought new batteries for my car and I wanted to protect my investment so I bought these based on various expert reviews. This model is good because it automatically "turns off" when the charge level drops so it doesn't completely drain the battery like some others. The installation is very easy. The LED indicates that it is connected and working. I would like to say that one positive point is that the company that makes them contacted me about a bug they found which they say could be rendering them inoperable. According to their description, it was an out-of-spec component. They sent a new one for free. This makes me think they are serious about their product and support it. I've only had about 6 months of use but looking at the battery cells I don't see any signs of sulphation. This is the type of object that takes a long time to evaluate. I can't talk about "rejuvenating" features because I started with new batteries. So far I've given 3 stars based on all of the above. My intuition says it will work as advertised and I would rate it higher if I had that kind of time test.
