How often should sealed lead-acid batteries be inspected according to standard maintenance?

• A. Quarterly
• B. Semiannually
• C. Annually
• D. Every 5 years

Answer: (B)

Periodic maintenance for sealed lead-acid batteries is performed on a semiannual basis. Even though these batteries are designed to be maintenance-free, they can develop issues over time that affect reliability. A six-month check helps catch signs of degradation such as loose or corroded terminals, physical damage, swelling, or abnormal voltages, and ensures the charging system is maintaining the proper state of charge. During the visit, you’d inspect the case for damage, clean and tighten connections if needed, verify voltage and, if possible, perform a light load-test to confirm the battery can still deliver the required performance. This interval balances thoroughness with practical maintenance schedules, whereas- quarterly would add unnecessary labor for most systems, annual could miss developing problems, and every five years is far too long for critical applications.
