+A [[http://amzn.to/2gEtVwL|battery waterer]] can make the job easier, and does not require one to judge water level visually.  The water "bloops" as it fills and stops blooping when the water is at the correct level.
 Batteries that are older, in poorer health, or are charged at higher voltages will be "thirstier".  Check water levels 1x/month until you know how they behave.
