WATERING AND FLOODED BATTERIES

4. Battery Maintenance - 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.
• Do not expose plates to air.
• Do not fill the water all the way up to the cap.
• Do not use water with a high mineral content.
Use distilled or deionized water only.
