camera life

[hunting maniac]

I have a stealth cam 3.0 megapixel digital camera and I am using the 6 AA batteries and it is lasting about 3 days with taking 1 pic every three minutes. I just purchased a 12v battery kit that stealth cam makes and was wondering how much of an improvedment of life I should be expecting. Since the battery is so much bigger I was guessing at least 2 weeks?????
Thanks Matt

lol. Might wanna take this to another forum, like the bowhunting forum, or deerhunting forum. This one is for technical help about the forum.
