I know people really like the Pro-Fill. I did, too, for several years. That is, until I took it off and visually checked the cells, at which point I found out it had been malfunctioning.
Before that, I'd heard about people whose Pro-Fills malfunctioned, but they never said exactly how, much less why.
Likewise, people always talk about how easy it is to fill the batteries, which it undoubtedly is. But they don't specifically say whether they've actually taken it off to check the batteries to see if it's really working. I, too, had sung the praises of the Pro-Fill, but I also failed to check the cells to see if it was actually filling them correctly.
It had never occurred to me that I'd need to take the thing off if the filling process was working well, and all I want to do is warn others who similarly might not think to visually check their battery cells.
And if you do check your battery cells, look in there pretty good to see if your batteries have developed any of this foam-like matter in there. If they do, be on super-alert because that foam stuff doesn't hurt the batteries, but it very definitely can make the Pro-Fill malfunction, and that will
hurt your batteries.
Hey, just trying to help. I wish someone had done the same earlier than I did and I could have known to be on alert.
