Clever it is indeed. The usefulness depends on how long that rechargeable
holds enough charge. If it's the usual three months or so I'd give it a
thumbs down.

If they were *really* clever they'd just suck power from the other batteries
in series to give themselves 1.5V. (Essentially a 1.5-4.5V boost coverter.)

Although obviously that doesn't work for Michael's one-cell remotes.

Are N-type cells the same diameter as AA's? Then you could just go back to
using primary cells.
