I went through this entire thought process just recently and decided to replace my two 6 volt lead acid batteries with 2 new 6 volt lead acid batteries. Looked at Trojan 105s but settled on a pair of Duracell Ultras from Batteries Plus. Dirt cheap, same warranty and easy. Originals lasted nearly 5 years so it seemed like the logical plan. I did add a remote watering system so I don’t have to fuss with checking the water quite so often. We’ll see how it goes.
