I was told by the interstate sale person that deep cycles should not be charged faster than 6 amp and AGM faster than 10. Just what she told me.
She's wrong.
Wet cells should be charged at no more than 10A. It will take a 20A rate, but the higher the current, the more heat at the post connection, and that will, over time weaken the battery. Heat is not a friend of batteries.
AGM batteries have much lower internal resistance, and can be charged at a much higher rate without the heat buildup of the wet cell.
AGM batteries are sensitive to overcharging. FLoat voltage should not exceed 2.30 volts per cell, or 13.8 volts for 12V battery. Some chargers can be configured for the different battery types. |
