We will send you batteries that are almost fully charged. Your UPS will finish off the charge, which helps it reset the battery cell itself. This means the system won't provide full runtime protection while it does this. If you can, do this initial charge without any load. We know this may not be convenient in many installations, but that is the best advice.

In this kind of device, you would expect the batteries to last between two and five years; this depends heavily on use and how the system is stored. Good ventilation: if it's in an office, do not use it as a bookshelf. Keeping the load low will extend the lifespan; ideally, keep it below 40%. They often run to the edge of their capabilities, and while they may be able to do it, it reduces the lifespan.

Please note that the information on this page is for guidance only. We have tried to help you find the correct batteries for your UPS system. If you are unsure, you can always check what you have before ordering. This will also show you how easy it is to change the batteries. If you look closely at the product code on your UPS, then you shouldn't go wrong.

Good fit. This was the second one sent since the first one was the wrong dimensions, through none of our fault. Eaton do two (at least!) battery dimensions depending on the sockets on the UPS it seems. BatteryTrader kindly sent the correct size out by return of post with all costs taken care of for the return.
