Specific gravity of electrolyte
Basic electrolyte temperature=20°C (68°F)
Note : 1. When temperature of electrolyte deviates from 20°C(68°F) at hydrometer check, temperature correction should
be made by the following formula.
S20=St+0.0007

2. When lowering of electrolyte level is due to spillage, replenish with dilute sulfuric acid of the same specific
gravity.
3. When replacing the battery, exercise extreme care so as not to make uncorrect connections, or damage to
alternator silicon diodes will result.
