These seemed like really good camera's when they first came out, but I have decided I don't to much care for them.
They do not run long on alkaline batteries either. It's rough when you put 12 batteries in a camera and it runs for a month or two and stops. I'd be inclined to use their recharable battery and try it out, except that is for the new version camera. If I have to spend $70 bucks for the solar charger, why not just cut my losses and get a better camera?
How many pics in that time frame? I run alkaline and my batteries are good at least 5mos minimum but, there's no bait piles in front of them.
A so-so cell signal is typically the cause of poor battery life.
