- APC Back-UPS BK1250 battery replacement
Installing the batteries in not a difficult job, well within the capabilities of most people, you should refer to your manual for the method, they are designed to be replaced, the ones we send to you will be almost fully charged but the UPS will still complete a service charge upon installation, it goes without saying that until this has finished you will not have the benefit of full runtime protection, you probably just want to install and go but its best to run the system without a load to so it can properly reset
It would be fair to expect batteries to last somewhere between two to five years in this UPS, this will vary greatly on conditions, the batteries will get hot in general use, the hotter they get the shorter the life so good ventilation is paramount, keeping the load low will also help extend the life span, in a ideal world keep it below 40%, they are so often run to the edge of their capabilities, while they may be more than able to, it will be at the expense of the life span
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
We have provided the information here as a guide, you should carefully check the code on your UPS as many of them are very similar so it's easy to make a mistake, the batteries are recyclable, more information about recycling can be found on our recycling page, link to which is at the foot of this page
