In Canada IKEA discontinued LADDA batteries. Too bad, they were cheap and good. I liked them.

Last weekend(Nov 5) Ikea Coquitlam was pretty full of them; sometimes they're sold out, even for weeks in a row.

It wouldn't surprise me if all these little 4 cell AA/AAA "smart" chargers were made in the same factory and basically the same inside. The Panasonic is the one I bought last year except I caught it on sale for about $24 with 4x AAA Eneloop batteries. It works fine. The Duracell charges in pairs which makes me suspicious about how it actually works. You really want a "smart" charger that does each cell individually.

NiMH cells became dramatically better around 15 years ago, I don't think they have changed much since then though. I've been using a LaCrosse BC-700 charger for mine, it works really well.

Kleinstein:
The battery indicators are usually made with alkaline cells in mind. So they have a threshold of some 1.1-1.3 V.  NiMH and NiCd have a rather stable output voltage of some 1.2 - 1.25 V and the voltage is not a good indicator for the residual capacity. A rechargable battery may show as good till 1% charge left or may show as empty when still 95% full, depending on where they set the limit. So a down-side of using rechargible cells is that the battery indicator gets pretty useless.

NiMH are more tricky to charge than the old NiCd and a poor charger can reduce the charge cycles a lot.  A charger from a battery company that comes with cells at least gives hot they would not sell a poor charger as this would also effect the cells reputation.

Is there any concern with a fast versus slow charger? For example Panasonic has these almost similarly priced chargers that come with 4 AAA, a slow 6 hour and a fast 3 hour charger as well:

Slow with batteries:

Fast with batteries:

I also see this brand EBL which is much cheaper. Comes with batteries and also individual cell charger. Any thoughts on it’s reputation as the specs seem almost too good:
