It does work, but take them OUT each time you're done using the device. Not for standby applications. Eneloop and similar long-lasting NiMH should work better than standard ones in this kind of application. Don't leave them IN anything I’ve used rechargeable alkalines, and

Don’t leave them IN anything

In other news, I'm looking into recharging regular alkaline batteries for my low-draw or infrequently used devices (remote controls, flashlights).
