Maintenance free batteries

Lately, I've been getting more and more riders with maintenance free batteries. I've always relied on a hydrometer reading to tell what kind of charge I have on a battery. What is the most relieable way of tell the condition of charge...other than putting a load on the battery and reading the voltage. Is there some sort of standard procedure to use?

You got it. The only other way I know of is to put a charger on it and read the amperage being taken in by the battery, but that doesn't give an accurate indication of battery condition.

When working on customers' mowers, I don't leave battery condition to chance very often. If it's dead when I get it, and it won't take a charge fairly quickly and hold it well, I just replace it. I'd hate for someone to try to start the mower I just "repaired" for them only to find a dead battery.
