I'm hoping someone can help me understand an issue I've had with a rechargeable battery. As described in another thread, I've switched over to rechargeable batteries. I also got a nice charger. The question revolves around some older batteries that I had and tried to use.
I had some older NiMh AA batteries that were sitting around so I charged them on a basic charger. and they appeared to work. No data at this point. Then I got a new charger and decided to do a refresh of these batteries to see what that was all about as it is a function on the new (better) charger. I ran the refresh and it indicated that the batteries took about 2300 mAh which seemed good as they are rated at 2500 mAh.
So I put them in my wireless keyboard and in less than a week, they were dead. I'm not too concerned about the batteries, but I'm trying to learn what happened. I thought that if they refreshed, they'd operate well, but that did not seem to be the case at all. Can anyone help me understand what's going on? My google searches just keep bringing up how to increase the battery life of a phone. No exactly the issue I'm trying to solve.
BTW, I'm recharging the batteries now and they are over 1800 mAh, so they do appear to be taking a charge.
