Check water, charge and use…only way to tell if they are any good. I wouldn't buy new ones till you prove they are used up. As for brands…used to work construction, remodeled a line in a battery plant, they made all brands!!!…just slapped different stickers on them and shipped them out. I was a believer in Sears Diehard batteries before that, now I buy cheap as possible…Walmart batteries have worked great for me!
