I have been using six sets of Energizer NiMH 2500 batteries for approximately two years. They have out performed other re-chargeables I have used. But I have notice recently that they are starting the downhill slide. I believe I have tossed two into the recycle container.
I have inherited the old family digital camera as a backpack camera. I use re-chargeables in it. I believe the current set batteries are older Energizer 2000. A while back I was using the camera in sub freezing weather and it was sluggish.
I do a lot of playing with the gps and the re-chargeable batteries are cost effective. I carry my gps in a cameral case to protect it. And I carry a couple extra sets of batteries with my gps.
As a change up I purchased a set of Sanyo re-chargeable and a charger. I returned them when I found the AA batteries would not fit in my mini-mag-lite. I should have held off on the return. One day I tried my Energizers and found they would not fit in my mag-lite.
A friend of mine and I do a fair amount of walking around with our gps hanging around our necks. One of the old hens seriously ask my friend if it was his heart monitor. But it points out that we use them a lot. Normally I have no problems with my gps because I do a fair job insuring that I keep my batteries charged. In turn my friend uses alkaline batteries. Two or three times a year his gps will suffer battery death. I have notice a couple of times that he is using the cheap alkaline batteries.
I would only use re-chargeable batteries in a flashlight if I had nothing else.
Now days I carry a extra set of alkaline batteries in the case I carry the gps when out hunting or extended hikes so the batteries can be used in my flashlight or gps. One of my chargers for NiMH batteries has a 12v adapter so I can charge the batteries on the road.
This hunting season I ran alkaline batteries a few days. The performance exceeded the NiMH batteries a notable length of time. But I believe my current NiMH batteries are getting tired and before next hunting season most of them will be replaced. I have had good luck using AA NiMH batteries in portable radios.
NiMH batteries are a money saver for me. But I pay close attention to keeping them charged. This reminds me that I need to pull out my radio box and recharge the batteries for portable radios.
