I had first used these on my stealth cams because of poor battery life but have found that they work on many different brands.No more buying D or C batteries.I hooked these to a 12 volt battery and they last all year.I have 6 cameras out and never worry about batteries going dead.
I bought the product to use with my StealthCam Unit. I will not use until the seasons get colder so I can save money and use my ice electronic batteries instead of buying AA batteries all the time!
