The batteries that we send to you will be almost fully charged but the system will still need to complete a service charge after installing, so it of course follows that there will be a period of time where you do not have the full protection that your UPS could offer until it has completed this operation, we know it is probably urgently being used but its best to run without a load to start so it can reset itself
It may be reasonable to expect two to five years from your new batteries in this UPS, this will however differ quite a lot depending on the use, ensure the system is not buried under piles of paper work as they often are in a office, the batteries get hot, the hotter they are the shorter their lifespan, try and keep the load below 40% if you can, while it may well be capable of more it will shorten the battery life
These are valve regulated sealed lead acid batteries and will not leak so there is no problem installing in tower or rack systems as they can be fitted on their side, both AGM and VRLA, they are not-hazardous so safe for busy data centres as well of course as the home office
The information we have provided on this page is a guide, you should carefully check the code on your UPS before ordering as many are very similar, the batteries are recyclable and environmentally friendly, more information about recycling can be found on a link at the foot of this page
