Using lithium double a's. my batt meter is at 99%. Camera was activated on 8/29/2021. So far so good. I am exploring buying a sealed, rechargeable 12v lead acid battery placed in a cheap plano ammo box and cableing it up to the cam, maybe get a year out if it then. Maybe even a 2 watt solar panel wired in, who knows then!How are your batteries holding up?
