Save your money and upgrade in my opinion. Go to all AGM batteries. Less maintenance all the way around. Also go for two 6 volt batteries for your house batteries that are also AGM. You will be glad you did even though it will be more money. Sure you can go to WallyWorld and get the cheapest flooded battery on the market and it will work. You will also be cleaning terminals and adding water. There are plenty of other maintenance items that will keep you busy.
