Installing the batteries is comparatively easy procedure if in any doubt refer to your manual for the process, they will come out to you almost fully charged but the system will still go through a service charge upon firing up, so it will follow that there will be a short period of time where you do not have the full runtime protection that your UPS could possibly offer you until it has completed this operation, if you can manage it the best advice would be to allow the initial charge to complete without any load, we know this may not be convenient in a lot of installations

A reasonable life span of batteries is between two to five years, this will unfortunately be very dependent on the general conditions its put under, do not pile books or files on top of it, it needs good ventilation, batteries will get very hot, if the vents are blocked it will get hotter, the hotter it gets the shorter the life, also do not overload with too many devices, quite often more are added over time, if you can keep the load below 40%, while the system may be of going higher than that its working the battery cell harder which will mean a shorter life span

The battery type is the preferred AGM or absorbed glass mat construction, they are also valve regulated, this 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 they are not-hazardous deemed safe for use in busy data centres, medical back up and of course the general home office

We offer the information on this page as a guide only, if you carefully check the code on your UPS then you should be ok but look carefully as so many are very similar and its easy to make a mistake, the batteries are environmentally friendly and recyclable, more information regarding recycling will be found at a link at the foot of this page.
