Using Electrolyte Specific Gravity Method
- Remove the battery filler caps and check the water level.
- If necessary, add water to the appropriate level.
- Measure the electrolyte specific gravity using a hydrometer.
- If it is less than the specification, recharge the battery. (See BATTERY RECHARGING .)
