Abstract
A battery which facilitates the measurement and recording of data is provided. The battery has a transparent casing wall and a scale attached to the wall for measuring the level of electrolyte within the battery. The scale contains first measuring indicia for measuring the distance the electrolyte level falls below a high level mark, and second indicia aligned literally opposite and having values, for example, specific gravity value correction factors, correlating to those of the first indicia.
