They are not generally considered "as good" as the East Penn product but are not horrible either. Johnson Controls is a huge company and has outsourced a lot of its battery production out of the USA.
Deka, Trojan, US Battery, Crown, Superior etc. all still produce their batteries in the US. Deka / East Penn builds a very good battery at a fair price (unless you get it at West Marine). IMHO US Battery is building one of the best batteries, also at a fair price. Unfortunately I don't have a local US Battery distributor so getting them is a royal PITA....
