I bought one last year for my car with a 4 year free replacement/100 month prorated warranty and now I need a new battery for her car and my truck and I go to Sears site and the only platinums they sell now are top posts only with 3 year free replacements. What gives? Am I already going to have to find a new AGM battery brand to go with? Who knows of any good AGM batteries that offer a 4 year full warranty or longer? And dont say Optima. Theyre garbage now.
