I have a Moultrie digital, the thing I found is the 6 volt rechargeables last alot longer in cold temps. I bought cheap batteries when I got it and they lasted about a week or 400 pics, but if they died you lost all pics. With the rechargeables it's about 3 weeks with some life left on the batt. The Moultrie digitals are about $130.00 at www.archeryexperts.com with the charger and battery for $30.00.
