Help: initial charge on new Crown 330ah batteries

Why don't you go to the Crown Battery website, and see what they recommend for charging procedures, volts, amps, charge rates, etc, etc. Once you find it and read it, post up the link to the website, for others to learn from.

Borrowing a charger to charge your brand new expensive batteries is not a good idea, buy the correct, non compromised equipment you need to maintain the batteries correctly, or don't bother.
