ABSTRACT:
A battery cap indicator has a transparent cap which permits the viewer to read both electrolyte level and density simultaneously, the indicators also giving the viewer the ability to determine whether the readings are at the higher or lower end of an acceptable range. The float assemblies of the indicator are configured for minimum friction with the guiding structure of the indicator body.
