Spills

for Nickel-Metal hydride battery:

The COROLLA CROSS Hybrid contains the same common automotive fluids used in other non-hybrid

Toyota vehicles, with the exception of the NiMH electrolyte used in the HV battery pack. The NiMH

battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues. The electrolyte,

however, is absorbed in the cell plates and will not normally spill or leak out even if a battery module is

cracked.

A catastrophic crash that would breach both the metal battery pack case and a metal battery module

would be a rare occurrence.

A caustic alkaline is at the opposite end of the pH scale from a strong acid. A safe (neutral) substance

is approximately in the middle of this scale. Adding a weak acidic mixture, such as a dilute boric acid

solution or vinegar, to the caustic alkaline electrolyte will cause the electrolyte to be neutralized. This

is similar but opposite to the use of baking soda to neutralize a lead-acid battery electrolyte spill.

A Toyota Product Safety Data Sheets (PSDS) is attached to this document.

• Handle NiMH electrolyte spills using the following Personal Protective Equipment (PPE):

• Splash shield or safety goggles. Fold down helmet shields are not acceptable for acid or

electrolyte spills.

• Rubber, latex or nitrile gloves.

• Apron suitable for alkaline.

• Rubber boots.

• Neutralize NiMH electrolyte.

• Use a boric acid solution or vinegar.

• Boric acid solution - 800 grams boric acid to 20 liters water or 5.5 ounces boric acid to 1

gallon of water.
