Back-UPS CS: Runtime does not exceed 45 minutes

Issue:

Why won't my Back-UPS CS run longer than 45mins with a low load connected?

Product Line:

Back-UPS CS

Environment:

BK350, BK500, BK500BLK BK350EI and BK500EI

Cause:

Safety Runtime Limiter

Resolution:

The 120v and 230V International Back-UPS CS models BK350EI and BK500EI, that were made before January 1st 2004, have a max runtime cap of 45 minutes. Anything made after that date will not have a runtime cap. Instead with out the shutdown software they will run until then have exhausted their battery.
