Watering
(Flooded batteries only)
Flooded batteries need water. More importantly, watering must be done at the right time and in the right
amount or else the battery's performance and longevity suffers.
Water should always be added after fully charging the battery. Prior to charging, there should be enough
water to cover the plates. If the battery has been discharged (partially or fully), the water level should also be
above the plates.
Keeping the water at the correct level after a full charge will prevent having to worry about the water level at
a different state of charge.
1. Do not let the plates get exposed to air.
2. Do not fill the water all the way up to the cap.
3. Do not use water with a high mineral content.
4.Use distilled or deionized water only.
!CAUTION ! The electrolyte is a solution of acid and water so skin contact should be avoided.
Procedure:
1. Open the vent caps and look inside the fill wells. Check electrolyte level; the minimum level is at the top
