Fibaro Leak Sensor Battery Drain and Configuration

Hi, I am new to Smartthings and I just setup a Fibaro Leak Sensor (ZW3) to replace my smartthings leak sensor since that one is not waterproof and I am using it in a sump pit which occasionally gets flooded. I am down to 88% battery after only an hour and perhaps 2 leak tests. Is this normal or can this possibly be a connection issue? I haven’t had any disconnects and it seems to be reporting temperature ok. Also, I see that there is a configure option but it is greyed out and I am not able to select it. Is there a way to access it?
