A battery cap indicator assembly, comprising:
- (a) a battery cap adapted to be connected to a battery casing top to cover over an electrolyte access opening and which has a lower interior portion which extends downwardly through the access opening,
- (b) the cap having a hollow upstanding transparent battery top which permits visual inspection of the interior of the cap,
- (c) an indicator flag disposed within the battery cap and which moves upwardly and downwardly depending upon the condition of the electrolyte,
- (d) indicator flag support means connected to the lower portion of the cap and to the indicator flag for supporting and moving the indicator flag when there are changes in the state of the electrolyte,
- (e) a second indicator flag is disposed within the battery top and which moves upwardly and downwardly depending upon the condition of the electrolyte,
