Battery load test notes indicate what acceptable score and replacement interval?

• A. Score at or above 90%, replace every 2 to 4 years
• B. Score at or above 70%, replace every 4 to 6 years
• C. Score at or above 85%, replace every 5 to 7 years
• D. Score at or above 80%, replace every 3 to 5 years

Answer: (D)

The test is about how to interpret a battery’s health from a load test and when to replace it. In alarm system upkeep, the backup battery must still be able to deliver power when needed, so technicians measure how much capacity remains under load. A passing result is 80% or higher of the original capacity, meaning the battery still has enough reserve to meet the system’s needs. When you see 80% or above, the recommended replacement window is typically 3 to 5 years, balancing reliable performance with aging concerns. If the score falls below 80%, you’d replace sooner rather than later to avoid a failure during an outage. The option with 80% or more and a 3–5 year replacement period matches standard practice for these tests and maintenance intervals.
