Questions about this item

How do I install the 12V 18A battery and avoid reversing the terminals?

Disconnect the UPS from mains power, remove the battery cover, unplug the old pack noting the red and black lead positions, connect the new 12V 18A unit matching the same polarity, then refit the cover.

When will the 12V 18A battery need replacement and what indicates end of life?

Expect three to five years of service; replace when runtime drops noticeably, the UPS sounds a replace-battery alarm, or the self-test reports a fault.
