Yes there are devises that are "supposed" to make things easier but they rarely do... How often water is needed can not be predicted but new batteries that are well cared for tend to use less water than abused batteries. My 2 year batteries have not needed water yet and sit on a float charger 24/7. I check mine monthly to every six weeks due to my work schedule. Yes water anytime after a charge and only cover the plates by 1/4 to 1/2 inch with distilled water only...
