Am now completely, or strictly speaking on batteries switched Eneloops, even for those with low loads such as clocks and remote controls. Clearly it is only once an investment, without question. But first, if each device is supplied and extras for the rapid exchange always ready in the drawer, then saves you from now on the battery department, and that is the long term undoubtedly good for your wallet and the environment. And this complete and frustration-free replacement is only possible with rechargeable batteries with low self-discharge. There are other brands, of course, but of which I have tested Eneloop are simply the best. You have at least the specified capacity, they are still full even if they were one year somewhere in a drawer, and I have never a battery "died" (had been about 3 years of use). What more do you want?
