Check electrolyte specific gravity --- every one month
The electrolyte specific gravity varies depending on the
electrolyte temperature. The specific gravity should be kept
within the range shown below. Charge the battery if the
specific gravity is below the limit.

NOTE: Measure the electrolyte specific gravity when
the electrolyte temperature is equal to the atmospheric
temperature. Do not check the electrolyte specific gravity
immediately after operation as the correct value can not be
obtained.
