Installing the batteries is comparatively simple, refer to your manual for the procedure if you are not sure, they will come out to you almost fully charge but the system will still need to complete a service charge upon firing up, during this interim period you should note that your system will not be able to offer you its full runtime protection until it has finished this task, while it's not always convenient it would be best to run without load to start so it can fully reset itself to the new battery energy level
In this UPS you could expect the batteries to last somewhere between two to five years, this will be very dependent on the use and the way the system is stored, ensure there is adequate ventilation around the device, do not block the vents, do not allow it to be used as a shelf to put files on, if the batteries overheat it shortens the life span, try and keep the load below 40% if you can, while it may well be capable of more it will shorten the battery life
The battery type is AGM or absorbed glass mat construction, they are also valve regulated, they means they can be used in tower or rack mounted UPS systems without the fear of any leakage, they will require no maintenance throughout their entire life span and are not-hazardous so safe for use in busy data centres and of course the home office
