What is the recommended procedure for storing a high‑voltage battery after service?

• A. Follow OEM guidelines, store in a safe, dry area with barriers or signage, do not energize, and restrict access until cleared.
• B. Store anywhere and power the system on periodically.
• C. Place in a ventilated area with no signage.
• D. Store next to flammable materials for easy access.

Answer: (A)

Protecting people and equipment means isolating and controlling the high‑voltage battery when it’s not in use. Following OEM storage guidelines ensures the battery is kept in the correct state of charge and environmental conditions, and that any required de‑energization steps are properly completed. Storing it in a safe, dry area with barriers or signage prevents moisture damage and warns others of the hazard, while barriers help keep untrained personnel from accessing it. Not energizing the system during storage eliminates the risk of unexpected startup or residual energy discharge. Restricting access until a qualified person has cleared it ensures the battery is safe to handle and ready for re‑use. Choices that ignore energy isolation, proper warnings, or safe environment introduce unnecessary risk, such as allowing energization, hiding hazards, or placing the battery near flammable materials.
