He said I might laugh! Then he said he has had great success with O’reilly batteries. He also talked about the issue of batteries sitting and having internal unseen issues. Anyhow, I checked online and when I enter the Testarossa O’Reilly does not show any compatible batteries. Not sure if this is due to rarity or incomplete data or what. I do see some for my 68 Charger. Anyone else ever used a premium O’Reilly battery?
