Figure 25-2 Battery Electrolyte Level
Add water only after charging unless the electrolyte is below the level of the plates. If the electrolyte level is below the
level of the plates, add just enough water to cover the plates and then charge the batteries. After charging, fill with
water to the level indicator. Filling a battery to the level indicator before charging will result in overfilling because the
electrolyte level will rise during charging and some of the electrolyte may bubble out of the cap. This reduces the
battery's capacity and corrodes the metal parts around it.
The electrolyte level should be checked weekly to be sure electrolyte is at its proper level (Figure 25-2, Page 25-4).
Never allow the electrolyte level to fall below the tops of the plates because this will cause the exposed part of the plate
to become permanently inactive. For best results, use a battery watering gun to add water to batteries. Check the
electrolyte level more frequently in hot weather or when batteries are old.

MINERAL CONTENT

For the longest battery life, use distilled water in batteries. However, if tap water is to be used, be sure the mineral
contents are below these levels:
IMPURITY
Suspended matter
Total solids
