14 month old maintenance-free battery, guys, cranks the engine strong but was leaking acid from one of the battery caps. All the other caps are dry. I noticed battery top was wet 2 months ago from under the mfr's decal. I removed the decal and saw acid had crept under that plastic decal from under one hole cap. Cleaned it with water with bicarbonate and exchanged the leaking cap with its neighbor. The leak transferred with the cap. Cap is not cracked. Charging voltage at 1200 RPM measured 14.2 volts so it is not overcharging.
I'm getting tired of having to neutralize the new acid wetness every 10 days with the bicarbonate. So I thought it might be a good idea to use RTV to seal it better. I have Arbo brand red silicone RTV in my parts bin, but its label does not say it can resist acid. Alternative idea is to drill a pinhole at the top of that cap to vent pressure. What you say, guys?
