Your opinion of Battery Desulfators

I have not used that newer model of Battery Minder, but I've used the older ones for 20 yrs, and believe what you want to, but you won't find anything any better on the market for maintaining and desulfating a LA battery. You can spend a bunch more money, but that don't make it work any better.

Hi All - A while back, only a couple of months after I installed my 2 GC2 245 AMP hour batteries and solar panels, I had an accidental removal of the breakaway pin which caused our 5th wheel brakes to lockup while parked and drew the batteries down to 8 volts before I noticed it. I managed to bring the batteries back, and they seem ok, charging appropriately when the sun is out to over 14 volts, then floating around 13.25 till the sun goes down. But I've been worried about how much I might have shortened the life of the the batteries by letting this happen. You people here are awesome, with an incredible amount of knowledge and experience to share, so I wondered what your opinion is of these inexpensive battery minder/desulfators is. They seem to get good reviews and people say they've extended the lives of their batteries. This is the unit I was Thinking of.
