Thread: Need advice on main and trowling batteries

I kinda wondered the same thing Brett. I mean 12 volts is 12 volts. Must have something to do with the conditioning function or something unique to the AGM technology.

It's just wires
Red to red
Black to black

Even Obama can't mess that up

OK, what do I set the battery selector switch that reads AGM or lead acid????

butch i use 2 onboard chargers, 2 banks each, one at the front and one at the back, each hooked up to two batteries parallel. i dont keep a charger on the cranking battery as i have nothing hooked to it but the motor and running lights. the motor keeps it charged. i use the 4 deep cycles for everything. longlining, drift fishing, and night stalking. i dont usualy have more than 3 fishing counting myself so nightstalking i use 3 led submersibles and three 60watt led lights each hooked to a small power converter so i can run 110 led lights to light up the interior.. been using this led set up and so far havent had a problem in the past couple years.

Here is why not, the AGM requires a higher voltage to make them charge thus the reason for changing setting in charger. Voltage set for Lead Acid and AGM never charges properly. Set forAGM then over time you continually over charge the Lead Acid and burn it up or warp the plates and it shorts out.

Kind of what I figured. Guess it is all or nothing on the AGMs. So far the lead acids have been more than adequate for me.
