This might be an easy one, but I need to make sure I don't blow up my clariion. I need to replace a SPS backup battery. I have ordered a new one and am ready to replace it. Is all I need to do is unplug the faulted SPS Battery, slide it out, plug in the new one and let it charge? It seems plug and play but want to make sure I am not missing a step. Thanks for the help.
