Your charger needs enough amps to quick charge in the standard 4 hour time frame.
You must charge at the 14.3 volt area, and thats what the 3 stage chargers do. Often the ones with a charge wizard..
My old 1 stage charger charges at 13.6 volts and max is 12 amps.( Takes days to charge my batterys)
The theroy is charge at 14.3 volts and max amps, say 100 amp chargers that are out there. The amps will taper themselves. Charge at 14.3 volts and all the amps you can until fully charged basically..
No we dont know what you have as far as chargers go...
