Forklift certification Refueling and Recharging Procedures Flashcards

What is a key advantage of lithium-ion forklift batteries during charging?

Answer: They allow opportunity charging without a cooldown and need no watering

Lithium-ion batteries support fast opportunity charging, produce no hydrogen off-gassing, and are maintenance-free.

If battery acid contacts your skin, what is the immediate first-aid step?

Answer: Flush the area with plenty of water

Flushing with water dilutes and removes the corrosive acid to limit chemical burns.

What is the risk of overfilling a lead-acid battery with water?

Answer: Acid overflow that corrodes the truck and creates hazards

Overfilling causes electrolyte to bubble over during charging, corroding components and posing an acid hazard.

Why should you avoid leaving a lead-acid battery in a discharged state for long periods?

Answer: It can sulfate and permanently lose capacity

Prolonged discharge causes sulfation on the plates, reducing capacity and battery life.

What indicates a lead-acid battery is fully charged during monitoring?

Answer: Specific gravity reaches the manufacturer's full-charge value and voltage stabilizes

A hydrometer reading at the specified full-charge specific gravity, with stable voltage, confirms a full charge.

What should be done with the charger before disconnecting a fully charged battery?

Answer: Turn the charger off first to avoid arcing at the connector

Switching the charger off before unplugging prevents a spark that could ignite hydrogen gas.

Why should smoking be prohibited during any refueling or recharging activity?

Answer: Both propane vapor and hydrogen gas are flammable and can ignite

Both LPG vapor and battery hydrogen are highly flammable, so any lit cigarette is a serious ignition risk.
