Posters here know that Lawrence is very proud of his smart charger.
I'm not sure about how one "pumps high frequency PURE DC" though. I
suspect he means pulsed DC.
A smart charger is nice if you can afford it. But the poster asks about
the charger that he has, not the neat one Lawrence purchased.
It doesn't matter if you use the 2A or the 10A charge assuming the
battery is rated to take charging at those rates. Usually they print
that info on the side of the battery. If it really is a small GEL
battery then maybe 10A is too fast. You better check that out.
If you don't have a smart charger, the key is to know when the battery
is fully charged and not go beyond that point. You can do that pretty
much with a cheap voltmeter.
Personally, I do not like to go away and leave a charger unattended,
whether it's a smart charger or not. And I own about every type made.
Too many things can go wrong.
