I wanted to post a follow-up review for the battery caps monitoring/filling system I referenced in a post previously. Over all I'm pleased and recommended them with the following comments: (1) the monitoring indicators move quickly as if initially "stuck" when adding water. I recommend adding the water slowly and flicking the tube with your finger first to "unstick" it. (2) get your condiment bottle and tubing at your local store(s). You will have less than $1.50 invested. (3) Don't squeeze the bottle when adding water. Let gravity do its thing.

I don't know why the pictures are sideways.
