Flooded batteries need water. But more importantly, watering must be done at the right time and in the right amount or else the battery's performance and longevity suffers.

General watering instructions:

• Add water, never acid, to cells (distilled water recommended)
• DO NOT OVERWATER
• For fully charged standard deep cycle batteries, add water to the level of 1/8 below bottom of vent well (see diagram A below)
• For fully charged Plus Series batteries, add water to the maximum water level indicator (see diagram B below)
• If the batteries are discharged, only add water if the plates are exposed. Add just enough water to cover the plates, then charge the batteries. Once fully charged, add water to the proper level indicated above
• After watering, secure vent caps back on batteries
