What Smart charger do I need?
I'm trying to charge 2 Sams Club gc2 golf batterys. I currently have a Shumacher SC8020a battery charger. I charge em a couple hours a day with not much success. They charge good from Alternator...

What do you think about the voltage being so high at first ?
I'm been concerned its going to damage my batteries so I've been turning the voltage down to about 15 volts
I don't understand. You have the adjustable voltage, so just set it to 14.8 or whatever, and it will do that. Normally once the batts are down some, you start a recharge at 14.8 (for most Wets) and after a couple hours or however long it takes, you dial it back down to 13.6 or whatever for when you are on shore power camping. when on shore power not camping you dial it down farther to your float voltage, maybe 13.4, depending on the temperature where you are. (13.2 is for 80F, 13.8 is for 50F, eg.)
It does not have voltage "stages" like the regular models do. You have to turn the knob when it is time to be at another voltage such as when home "floating"
With nothing in its DC output terminals, you can turn it on (120v powered up) and use the voltmeter and knob to dial around marking some voltages beside the knob so you can twirl it to that when it is all connected. (When connected, the built- in voltmeter reads battery voltage, not the voltage you want the battery to get to, so you have to mark the target voltages when it is not connected) Here is my 55 amper: (The meter will show the battery at its target voltage when it gets there, but that does not mean you are finished the recharge, just that you have reached your absorption voltage)
