14. Hydrometer Testing The Batteries
•
To do an accurate test, the battery water level must be high enough to
extract enough electrolyte to fill hydrometer so that the float floats.
Water should be added prior to charging in order for let the electrolyte
to mix.
•
The greater the variation between cells readings, the greater the loss
of run time. For example, if the readings are 1.265, 1.265 and 1.225 in
one 6 volt battery. The low cell would be considered weak and greatly
reduce the performance of the battery or shorter run time. This
battery would have a point 40 variation. Batteries that have weakened
cells in most cases it can still be used as long they continue provide
adequate run time. A battery with a point 40 variation or more should
be determined defective.
