I have 4 Cuddelink J series and 1 G series as well as the Home unit. Battery life with alkaline was pretty bad. I was only getting a little over a month. When the solar panels came out I bought 3 of them for the J series, nothing available yet for the G. One camera went dead in 17 days, the next in 52 days and the last in 62 with the solar panels and rechargeable batteries that come with them. This is ridiculous considering I have a camera with lithium and it's still running 88 days as of today. I tested the panels out in the woods and got just over 9 volts, the Cuddelink cameras all run on 9 volts so this shouldn't be a problem. The problem is the batteries they send with them are cheap and junk. Every camera that went dead had at least 2 batteries that wouldn't take a charge. This has happened to others on Cuddetalk. I tossed the batteries and put Rayovac rechargeables in 2 of them and haven't had an issue yet but it's only been about 20 days. The other 2 I hooked up to HME solar chargers with 12 volt batteries I've modified with 9 volt regulators. I'm seeing the same thing everyone else has otherwise. about 350-450 yards through thick coverage and great trigger speed. Some of the pictures sent back to the Home aren't the greatest but the full size is still on the cameras SD card.
