Q: Why can’t I use boiled water, filtered water, or rain water?

A: Even though these types of water seem pure, they are not suitable for your battery.

• Boiled water only removes pathogens; it leaves behind the harmful, corrosive minerals and salts.

• Filtered water (like from a pitcher filter) only removes large particles and doesn’t eliminate the microscopic dissolved minerals.

• Rainwater collects atmospheric pollutants.

Your battery requires de-ionized (DI) or distilled water with a Total Dissolved Solids (TDS) reading of zero—which is exactly what we provide—to prevent mineral buildup and battery damage.

Q: How can I tell if my battery needs water? What is the sign?

A: The most reliable way is to visually check the cell caps.

• Carefully open the cell caps and look inside. The lead plates should always be fully submerged in the electrolyte liquid.

• If you see the tops of the lead plates exposed to the air, the water level is too low, and you need to add water immediately.

• Neglecting this causes the exposed plates to harden (sulfation), leading to permanent loss of capacity.

Q: Should I add water before or after charging my battery?

A: You should always add water after the battery is fully charged.

1. Check Before Charging: If the plates are exposed, add just enough water to cover the exposed plates. Do not fully fill yet.

2. Fully Charge: Charge the battery completely. The charging process heats the electrolyte, causing it to expand.

3. Top Off After Charging: Once the charge is complete and the battery has cooled, top off each cell to the correct fill line (usually about 1/8 inch below the vent well). This prevents overfilling and overflow.

Q: Why do batteries only lose water and not acid?

A: The sulfuric acid (H2​SO4​) in the battery’s electrolyte does not evaporate; it chemically bonds with the lead plates during the discharge process. The water (H2​O) portion, however, is consumed.

• During recharging, the water molecules are split into hydrogen and oxygen gas (a process called “gassing”) which then vent and escape.

• Since the acid remains, only pure water needs to be replaced to maintain the correct chemical balance. Adding acid would actually damage the battery by making the electrolyte too concentrated.

Q: Can I use this water for my AGM or Gel (sealed) battery?

A: No, our water is only for Flooded (or “Wet Cell”) Lead-Acid batteries.

• Flooded batteries are designed to be maintained, requiring periodic water top-ups.

• AGM (Absorbed Glass Mat) and Gel batteries are “maintenance-free” and sealed. You should never attempt to open them to add water, as this will destroy the battery’s chemical seal and void the warranty.
