I have been using Lexus or Toyota batteries for years. Most never make it to their 60 month (Toyota) or 84 month (Lexus) guarantee. However, my Lexus dealer always treats me right. However x2, I am responsible for 11 cars so I want to minimize my work, if that is possible. I got one of those battery checkers that checks the CCA and it has "saved" 2 of the ladies and me in that I was warned me that the batteries were bad before they actually died. Therefore, no body was stranded. I want to try East Penn/Deka and can get East Penn from the local Federated or NAPA at the exact same price ($115). My preference is to buy a Deka battery which I believe is East Penn's own brand. Where can I buy a Deka battery? I guess I could call Deka Monday but was thinking you could guide me. The Lexus battery has less CCA than either of the East Penns at Federated and NAPA but maybe that doesn't mean that much. My brother takes care of a fleet of buses and told me to go pick up the same group battery and the Deka would be a lot heavier. He can't buy Deka as he works for a government agency that tells him where he has to purchase batteries. Another thread. Do any of you know who makes Lexus batteries for NC?
