question

Volts? Amps? Amphours?
Asked by: Anonymous
This is the OEM replacement battery. You can look on the APC website, and get fully detailed technical specifications. I attempted to copy/paste the link for you, but that is not allowed as a response here. So, just go to the APC website, and type RBC2 into the search box.

question

It is interesting that the SPECS do NOT list the voltage nor the Amp Hour rate of this battery. Perhaps by knowing that it is model RBC2 one should KNOW this info but I expect to find such basic details as volts and AMPS of a battery in the SPECS.So, what are those two numbers for this battery??
