RE: 12v 7.2Ah Lead Acid - Charging?
Yes, possibily, but you don't want to over charge. With the charger you are using it would be easy to over charge; you have no control like you would with an automatic charger. I suggest you get an auto shut-off type (car charger) that will reduce the rate as the resistance in the battery increases (as voltage goes up). Then you can hook up and forget it. Yours will work but 600 ma will charge a 7ah battery fairly quickly, assuming you don't draw it down much past 11 volts. I you charge it for 2-3 hours a week it should be OK. I put a Radio shack volt meter on my box to monitor my battery. When it gets to about 11.5 volts I cherge it with a 500ma charger for 3 hours. This keeps it up for my starter.
