You need a charger that is set up for continuous 40 amps. the Schumacher chargers that are inexpensive won't charge continuously at 40 or 50 amps. ( the cheap ones only charge at 40 - 50 amps about 5 minutes before kickin out) I have 2 optima batteries and I use a black and decker charger that is set up to charge continuously at 40 amps and reducing as needed.The Optima battery guy told me to charge them hard. Optima has their own chargers available now and they hit the batteries pretty hard. He said don't trickle charge them give um some juice. I hope this helps. Dave.
