Use a battery charger and understand the needle gauge and how it can provide helpful hints if a battery is bad. Besides, if you don't have a battery charger, this is yet another reason to get one with an AMPs gauge. It is so convenient to charge battery's yourself. Is it free locally? Yes, but charging a battery slower is key to battery recovery.

When I'm at work typically I use an expensive battery tester. Sometimes I need to use a battery charger at work, when I do, I don't have to go back to the battery tester to see if it's good because I can tell by paying attention to these gauges.

A battery shouldn't have leaves on it, rarely, I've seen poor connections make fire. Diagnosed one the other day. The car was acting like it had a bad MAF, battery, vacuum leak, or issues making consistent fuel delivery, all from resistance in the connections making a fire.

When cleaning up these connections get between them all. In the fire case above, the main clamp to the battery terminal had no issue.
