A built in hydrometer only indicate if the state of charge is above 65% in one cell. Green indicates at least 65% charge. Dark indicates 65% or less charge. Clear indicates low electrolyte level.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
