Adding Water to VRLA (SLA) batteries?

If you raise the voltage higher they will bubble and vent, sometimes making louder venting noises. The fact that they are called VRLA (valve regulated lead-acid) means they have a valve to keep the battery from venting unless the pressure gets too high. In my experience, it makes perhaps 20% difference (maximum).
