I use rechargeable alkalines, Rayovac Renewals, to be exact. You will be
amazed at how long they last. I do not wait for them to be fully
discharged. It turns out that, with 2 sets, I recharge every couple of
months. So far, they have not degraded in use or leaked gooey stuff. I
think that warning applied to an older generation of batteries.
I have nothing against NiMH's; I use them exclusively in my digital camera.
