I've been considering buying an alkaline battery recharger for the AA and AAA batteries I use and chuck each year.
Does anyone have experience of these and how effective are they?
I'm getting fed up of Ni-Mh batteries only to find they're flat when I go to use them a week or so after charging them up.

I have no personal experience of them, but they've been around years and still don't seem very common, which leads me to suspect they're not much cop.

Although they're more expensive, and slightly lower capacity, get some hybrid/LSD NIMhs. From personal experience they do hold their charge much longer than normal NIMH,
Sanyo Eneloop is one brand , there are others:-

EDIT: Uniross Hybrio at a similar price:-

I still have one bought several years ago but the required rechargeable alcalaines dissapeared from my supplier (Maplin).
Worked well with my Sony radio which detects 1.2V NiMH as being dead.

Most digital cameras these days have an option somewhere in the setup menus to choose between alkaline and NiMH to stop this happening.

Looks like you can still gets rechargeable alkalines on eBay, almost exactly the same prcie a sthe Eneloops, although presumably 1.5V not 1.2V.

I thought the chargers referred to by the OP were able to recharge any AA cell, regardless of type.

Fair point, I'll shut up about the batteries.

Except you cant recharge any AA cell regardless of type.

That's what I always thought, but I've seen one in Lidl which says you can.
Unless I've misread the packaging, but I don't think so.
I'd post a link, but Lidl don't put all the stock on the website.

Wikipedia says you can recharge some alkalines:-
en.wikipedia.org/wiki/Recharging_alkaline_batteries
Although charges and batteries have never been common.

You certainly can recharge primary AA and AAA batteries, 'cos I have done it. I believe they can explode if charged too fast, so I used a constant current source at a few mA, over several days. Certainly worked, but I got fed up with the long charge times and now use Lidl Ni-MH which are fine if the product can work with the lower voltage that these rechargeable batteries have.
