So last night there goes a bump in the night. I grab my M&P with a trl1 attached. I rack a round in the chamber and crack the bed room door open. I begin to clear the house. ( surprised the light did not blind me)I clear the bathroom, I clear the nursery, I clear the office and as i clear the guest bedroom the battery dies. I think to myself "great" but my night vision isn't totally gone. I move a little slower and verify house is clear. It turns out it was the shampoo that fell into the tub. So the lesson here is dumping a new set of recharged set of batteries and doing a quick turn on and off isn't enough. (Do a full charge and full discharge before trusting the batteries)Turns out one of the batteries is a defect and wont hold a charge for more than 30 seconds. Also the wife said I left her alone without a gun, so looks like there will be 2 night stand pieces going forward.
