ULTRALOQ Bolt NFC - Batteries dies in less than 1 month

The out of the box batteries on my ULTRALOQ Bolt NFC died in less than 1 month. We installed this on a new home office that we are building in our back yard. The Wifi signal is intermittent at the moment - once construction is complete we will setup a repeater and boost the signal.
I replaced the OEM batteries with rechargeable. They were very difficult to install - kept popping out. These only lasted a couple weeks and appear to be dead. I have August locks in the house and use rechargeable batteries. I recognize they do not last as long, but I cannot be tossing 8 batteries in the trash every couple months - this is irresponsible and wasteful.
Will the better life improve with the Wifi signal?
