What inspection should precede charging a battery that was used earlier in the day?
- A.Charge immediately while the pack is still hot to save time
- B.Charge a swollen pack slowly to restore it
- C.Check for swelling, damage, unusual heat, or odor, and do not charge a pack showing those signs
Correct answer
C. Check for swelling, damage, unusual heat, or odor, and do not charge a pack showing those signs
Why
Charging stresses a battery, and charging a damaged or overheated pack increases fire risk. A brief inspection, and letting a hot pack cool as directed, should come before connecting the charger.
