I had a problem last week with a receiver and it had a battery status if 50-75% at a restart. The next day it was went to a 0-25% and died hours later. Last night on my other sons system the transmitter said 25-50%. I usually would change them but I only wanted it to run two more days then do a brand new sensor. Less than 15 minutes after the restart the transmitter battery(Energizer) just flat out died. I guess it just skipped the 0-25%?
