I tried the "high dollar" (everready "e") and all I got was 4-5 days! I called Stealth Cam and they said to send it back to them and they would replace it. They said it would take at least 3 weeks!!! Our bow season starts Oct 1 so that really "sux" but I think that is my only option at this time. I was wondering if anybody has tried a 12 volt battery hooked to the solar charing port on the bottom of the unit? The solar charger that Steath Cam sells is 12 volts so I can't see why a regular battery won't work, even if it over charges the recharable batteries and fries them they should last longer then 4-5 days!
