Have you ever looked into rechargeable batteries Mom? Amazon has some decent deals.I already spend a fortune on lithium batteries for all of my trail cameras. I just order 100 at a time every few months. I have a huge box to go to recycling and missed taking them to the annual clean up day last Saturday. I realized on Sunday that it had been the day before. I may need a bigger box cause I think I missed it last year too based on how many are in there.
