Question #: 52
Topic #: 10

A UPS has an internal battery tester, do you still need to separately test the batteries at block level?

ANo, as mentioned the battery tester is already built-in the UPS.

BNo, the UPS will automatically generate and alarm when de battery voltage is too low to operate.

CYes, the UPS will only test the batteries at string level which only gives an indication on the overall status of the battery string. Measurements at block level will provide more detailed information on the status and remaining lifetime of the batteries itself.

DTesting batteries using the built-in battery tester or resting the batteries at block level does not increase the battery lifetime, therefore it is not recommended.

Show Suggested Answer

Suggested Answer: C

Block-level testing identifies weak or failing individual batteries that may not show up in string-level tests, enhancing overall system reliability.
