Simplest and neatest way we've found to water our batteries. Buy an enema bag, fill it with distilled water, screw in a hook over or near your battery bank, hang the bag on it. Using the spring clip stopper nozzle on the end of the hose, fill your batteries to the proper level. The flow rate is just about right for reasonably quick fills, but allowing you to monitor the level as you fill. Easy to refill. No muss, no fuss!

It works just fine, considerably speeds up the process of topping off the cells, and does NOT touch the top of the plates. The tip has a flange that is slightly larger than the diameter of the holes, to prevent the tip from extending too far into the cell. Based on what others on the list describe as their number of batteries, such as 16 for a house bank, I consider my housebank of 6 golf cart types and my engine-starting bank of two 8D's to be fairly modest. But even so, properly topping off 8 batteries, some in places slightly difficult to reach, is significantly eased by using this filler. A genuine caution that people should remember is that the tip of the filler has been dipped into sulfuric acid and should not be touched at all. Important to remember when removing the filler tip to put more distilled water into the filler. I think we can both agree that topping off the cells is important, yet something that many put off for prolonged periods when it's a difficult task to perform. I find the use of the filler you described considerably eases the chore and let's me top off my 30 filler chambers quickly and neatly and topping off is no longer a chore that I hate to do.
