I got the rechargeable NIMH batteries by TENERGY off the net and they are working great. Went 6 months in my Bushnell cam, which takes AA batteries and was still going strong, but my Cuddeback which uses D batteries was dead at about 2 months. Even regular batteries go dead pretty quickly in my Cuddeback though. I figure if the chargeables last 4 soaks, they will have paid for themselves. They are sure working good in my Bushnell cam right now....I tell you what. Good luck
