Thread: Rechargeable batteries draining without use

If I have not used the spares for a couple weeks I put them on the charger to top them up before use. When I put them on they seem to be drained a fair bit going by the indicator on the charger.
They can take around 2 hours to top back up.

Is that normal or do I have some duds?
It happens with both AA and AAA
