Questions about this item

How do I install the 2XRBC2SLA278 battery cartridge into my Belkin F6C525-SER UPS, and what step is often missed?

Power off and unplug the UPS, remove the front cover, disconnect the old cartridge leads, insert the new 12V cartridge, reconnect the leads observing polarity, replace the cover, then power on and allow the UPS to charge for several hours before relying on backup runtime.

When will the 2XRBC2SLA278 lead-acid batteries need replacement, and what indicates end of life?

Expect three to five years of service; replace when runtime drops noticeably, the UPS signals a battery fault, or the units show swelling or leakage.
