Not a big believer in name brand stuff, cat doesn't make any batteries, they are sub'd out and bought from a supplier, thus someone else makes them, like all manufacturers do no matter who they are, I've had good and bad batteries from all the major companies, to me the cat logo on the side means very little, they buy from whoever is the cheapest that meets their specs, not the highest priced, the cheapest, so if they put it out to all five battery companies the one with the lowest price gets cats business till the next bid letting. Its business and they all do it.
