Terrible Sewer Gas Smell Solved Thanks to RV.Net

You're lucky they didn't explode on you.. Still happens...

This is usually caused by the older single mode converter/chargers that put a constant 13.6VDC which is right on the edge of boiling out battery fluids over an extended time.

When I was using one of those converters I always checked my battery fluids on a regular basis. After I changed the converter/charger out for the multi-stage smart mode charging type I still check my batteries out of habit but never find them low on fluids anymore.
