Pathetic battery life
I think the ones that came retail on the cameras should have been warrantied. They are slow to respond. I had no choice bug to buy the same small proprietary battery they sell. The system is way to nice to have suboptimal batteries.

First I apologize for this problem. We had a bad batch of batteries and do warranty the batteries from two years from the date or purchase. Please fill out the RMA request at the link below and we can get you taken care of. https://www.longshotcameras.com/pages/rma-request
