It is intended for administrators who need to restore runtime on that specific UPS model. ||

Verify UPS model before ordering

Confirm the unit label reads SU3000RM3U; other APC models use different cartridge numbers and will not accept these batteries. The pack contains two cartridges, so ensure the UPS requires exactly two for a full refresh. Buyers needing a different voltage, capacity or form factor should look elsewhere.

Questions about this item

What comes in the 2XRBC12SLA1219 pack and is any extra hardware needed?

The pack contains two 12 V lead-acid cartridges that slide directly into the SU3000RM3U; no extra cables or brackets are required.

Should I choose the 2-pack or a single cartridge for my SU3000RM3U?

The SU3000RM3U uses two cartridges at once, so the 2-pack replaces the complete set in one step.
