I've used a few types and none are perfect and 100% foolproof. Currently I use
and like Pro-Fill from Jan Water Products and customer service is great. PLEASE
NOTE: IMHO no watering system should go full automatic and be left unattended
during a filling process. Murphy's Law will bite you in the butt with a stuck
valve and then battery top flooding. I learned this one the hard way many years
ago when a very large battery bank at 250Vdc nom. flooded and the ensuing short
started a fire that was not insignificant (is any fire?). I feel that any
battery bank that can be filled in under 30 mins does not justify a watering
system. Although a lot can be said about the benefits of minimizing the chances
of electrolyte contamination, splashes on you and your clothes (of course you
have goggles on!), spilling water all over your battery tops anyway, and
sometimes awkward back-breaking access (unless it's an EV why did you put them
there?). My customers that have over about 60 cells to fill really appreciate
the filling systems in spite of the somewhat high costs.
