We will send out batteries that are almost fully charged, after fitting the UPS will top up and complete a full charge, you should take note that while this is happening the system will not be able to offer the full backup runtime period until its finished, while you might just want to install and go, if you can it may be better to start without load until its completed its first charge, this will give the system chance to reset to the new batteries properly
While many large institutions might change the batteries every 1 or 2 years without fail, you should expect somewhere between two to five year life span, this will however differ quite a lot from user to user depending on the use, ensure there is plenty of ventilation around the device, do not cover the vents or place it next to a radiator, do not use it as a book shelf, if the batteries get to hot all the time it will shorten the life span, keeping the overall load low will also help prolong the life span, in a ideal world keep it below 40%, many systems are run to the maximum of their capabilities, while they may be able to do this it will have a adverse effect on battery life.
These batteries are sealed lead and valve regulated or VRLA and benefit from advanced AGM technology, this means they will not spill so can be mounted on the side in a UPS without any fear of leakage, they can be used in rack or tower modules, they are not-hazardous so safe for use in mission critical environments including busy data centres or medical back up
