Rechargeable Alkaline v NiMh

** NiMH cells have a lower terminal voltage and high self discharge rates - making them unsuitable for applications that do not require high current or where a long time span between replacement is important, like a wall clock.

It may well charge the both in the same way, seeing as only one rather special type of alkaline cell is specified.

Not completely true about high self discharge rates. There is an increasing amount of 'LSD' NiMH cells. Eneloop started the trend but I've seen at least five other major manufacturers have followed suit. (I have some Varta and Panasonic LSDs along with a heap of Eneloops.) I use them in everything from remotes and wall clocks to LED flashlights and my camera. They last between two and three years in remotes and I can't tell you in the wall clock as it's already gone for three years, longer than an alkaline cell would have.

For flashlights and cameras - use Eneloops, but for wall clocks or TV remotes it's nuts.

You call it nuts I call it principle. I refuse to use a single-use cell where I can use a rechargeable. Not all priorities have to be about money.

But my wall clock and wireless door bell will not work long or at all if I use NiMH cells - the terminal voltage is too low.

My clock's fine but alas, the wireless doorbell that I bought from Jaycar simply won't work with NiMH cells (and stops working when alkalines are only half-used). It's the only device that I use which doesn't take rechargable cells.
