I bought your 3300 tender with my factory order 2015 corvette. I was injured and unable to drive for 3-weeks. Battery was dead. How many will the charger take to charge my battery. It has been hooked up 96 hours and no charge yet.
Thank you,

    Check everything with your 3300 first. If everything ok, maybe the problem with your battery friend. I saw its been hooked up quite long but no charge
