Must be battery question day with these posts. I have 2 batteries for starting and 2 for the house in 2 compartments. The stating batteries have 7 in. above while the house batteries have 6 in.. Lots of side room. I can not get a filler bottle in there and don't want to have the water lines. I now use a baster to add water, which is hit a miss on how much water is in there. Found a 1L bottle half the size of the others. It is in England if I want to order it. How do you guys fill your batteries with water and get it right?
I use a mirror to check battery level. If battery needs water I use the mirror and a Battery Filler Rubber Bulb. The tube end is smaller than a baster and is flexible.

I use a 3 oz Dixie cup and a mechanics mirror. It has a flexible head and telescoping stem. Use a flashlight and the mirror to see in there then add water slowly and keep checking so as to not go above the split ring.
