Amazon needs to have someone proof read the descriptions on products sold.This one shows the dimension as:
“Product Dimensions as 5 x 10 x 9.7 inches; 1.6 ounces”.
Whats with the weight number? Or is it the capacity? Or is meaningless?
Of course being translated from Chinese answers the question.
This happens all the time on Amazon.
Had one. It also took up a chunk of the storage bay and had to placed such that it couldn’t accidental tip over and leak. Oh and distilled water is generally sold by the gallon – so the excess also took its anti-tip storage room. And the dispenser is often too big to get to the battery without removing the battery from its storage.
I solved the whole issue. I now only use AGM (a/k/a maintenance free) batteries. I gave my dispenser to a fellow RVer who had an electric golf cart.
Good points, Jim. I’ve been satisfied using a turkey baster. Cheap and I don’t need to remove batteries.
We used those in gas stations where I worked. They won’t work in an rv where your battery compartment lies under something else (very common). Dustin is talking about trailers that don’t have that problem.
Boy does that bring back memories!!!!
The most simplest device I have found is a plastic Heinz Ketchup bottle – it already has a 1/4″ hole in the cap – simply insert a length of clear tubing long enuf to reach your battery port while holding the bottle vertical and also the fluid to the bottom of the bottle. Simply insert the tube in fluid and battery and “gently” squeeze the bottle. Only lasts about 5 years and it is recycling too! (Always use distilled water!) Pull the tube up out of the bottle water before moving or transporting.
Thank you, Dustin! Cool idea. Have a great weekend and safe travels!
