What''s the big deal?
I think the charging regimine and maintenance is more important than the battery manufacturer. At less than $100 for a pair, give them a try. I did.
I bought two pairs. They have worked flawlessly for year and a half now - and I am on the hard in the Nevada desert, with extreme heat, running powertools off my Freedom 15
inverter, with my only charging source a 60w solar panel.
I have no complaints. Plus, if they die soon, I don''t have alot invested in them.
Many people are very brand loyal and that is okay. However, as it turns out, there appears to only be a handful of battery manufactures in the nation who package their products for different retailers. For example, Exide makes a car battery that you can buy at WalMart for $26. The exact same battery at AutoZone is $40 with the AutoZone label. It pays to do research before making any decisions
