Questions about this item

Does the LEADACIDSLA12-20 include cables or mounting brackets, or must they be purchased separately?

The battery is a direct replacement cartridge for the APC SU3000RMT3U and fits into the existing RBC12 housing, so no extra cables or brackets are required.

Is the 20 Ah capacity the correct choice for my SU3000RMT3U, or should I look for a different rating?

The 12 V 20 Ah specification matches the original RBC12 cartridge used in the SU3000RMT3U, making it the appropriate capacity for that UPS.
