See the post from Steve Dashew as follows: Do Hydrocaps Really Work? by Steve Dashew July 14 , 2001 BEOWULF has been sitting at Atlantic Yacht Basin in Norfolk, VA for the past two months. She's had her Trace inverter connected to shore power, acting as a battery charger. Before we left her we topped off the batteries. We've been using Hydrocaps for 15 years to reduce battery water consumption and help keep the battery tops and terminals clean of acid buildup. They seem to work, but it is always nice to know for sure. So we decided to conduct a "scientific" experiment. We replaced one of the Hydrocaps with a normal cap. This morning, when I checked battery water level the 11 Hydrocaps were topped off. However, the single cell with a normal cap is showing the top of its plates--Hey, these things really do work! On a related subject, the battery tops were spotless nine months ago. They still are. That's also a function of the battery caps, and the fact that all terminals are heavily coated in Vasoline.
