have you had the battery load tested yet? Check your connections, make sure they are shiny clean, I use neverseez on all battery connections, it is conductive, and a corrosion inhibitor. I know someone will say neverseez is unsuitable for this duty, and the only thing that is applicable is T&B coprshield. The only real difference is the price, and neverseez actually publishes electrical conductivity data on their website. And no neverseez doesn't have lead in it. Lead is bad...
