I did, the ones I have don't keep the state of charge as long as the lower capacity ones. I have some for a light and I tried them in my camera. I get more useful life out of the lower capacity radio shack ones.
I stopped using the high capacity ones after a few runs.
If I leave them for a day they are way too low. Also the fast chargers wear out the batteries faster, the faster they charge, the faster they wear out the batteries.
