Re: Any particular brands of AGM batteries to avoid?
I would avoid Optima since they are now made by Johnson Controls. I have used Optimas in several applications over the years and been very happy with them. I installed one as a starting battery in 2005 and, despite being abused because of a phantom load which took forever to identify, it lasted until 2017. I replaced it with the "same" and, only after purchase realized that it was no longer made by Enersys. After a little over two years it would no longer hold a charge. Just one data point but I just replaced it with an Odyssey which is the current Enersys brand - fingers crossed.
