• HP Compaq R5500XR-ERM extended runtime module battery replacement

The new batteries that we dispatch out to you will be almost fully charged but the system will still need to fulfil and complete a service charge after installing, you should note that while this is going on the system will of course not be able to offer the full runtime backup time period until it has finished doing this, 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

Fitted in a UPS you could expect a battery life span of between 2-5 years, this will though vary greatly on the general conditions, the batteries will certainly get hot in general use that's normal and it follows that the hotter they get the shorter the life so good ventilation is paramount, 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.

The battery cells are constructed using absorbed glass mat technology or AGM, they are also valve regulated sealed lead acid or VRLA, this is the recommended type of battery for this installation, they will not leak if mounted on the side so safe to be used in a UPS tower or rack mountable configuration without any fear of spillage in mission critical applications like a hospital or busy data centre as well as the home office
