Thanks for sending the article! Finnish is not my mother's tounge, but I tried to read the thing about the cheap one and understood it well.


Hmm, how do I know that even the Vanson charger (40-50€) is even better than this one? Seems to me, either buy a 70€ one, real good brand...
Yep, that article showed really well difference between very cheaply sold lousy, "non individual" charger and better charger which got much more out of very lousy cells.
I don't remember where but some other magazine had also NiMH battery test in which they found some general "supermarket" NiMHs had quite much worse capacity than known brand batteries.


Actually that "ultimate" NiMH AA charger costs 59€

Can't compete in speed with fastest chargers and some special charger/battery combinations (like Varta in that test) but in other features it beats other chargers...
And I just don't think that those special fast chargers are so good (16 min charge with Varta), because even for 2000 mAh cells that would mean almost 10 ampere current per cell meaning even slightest resistance, like contacts on battery ends, generates lot of heat. (remember equation P=IIR)


But before buying charger+batteries you might want to think what camera you're going to buy, quite big part of digicams use proprietary (or "poropietari" Finnish slang... compare to word "poropeukalo") Li-Ion batteries and naturally NiMHs are quite useless with them.


BTW, When working with different languages Webster's Online Dictionary is really good tool, I use it more than dictionary next to keyboard.

Mm. If that one is59€... Why is it so hard to find35€ ones in the shops (I live in Turku by the way), that are of a decent brand&are individual.
I'm buying the kodak z740 I think. It uses NiMhs.... hmm, when it comes around, they use CRV3 too I think. Maybe I should buy a crv3 rechargable and a charger? Or are we talking the same situation (i.e. only not soo good onesare below35€)?

The people at clas ohlson soon will think I'm there stealing. Payed another visit today. There's a CRV3 recharger with a rechargable battery for 34€.Product:36-1994.

Am I safer off buying one of these, orcould this also be budget crap?

Propably because better chargers cost more...
(and because El Cheapos give better profit margin)

1350mAh... looks quite low capacity compared to AA NiMHs.
3V x 1350mAh=4050mWh
2.4V x 2300mAh=5520mWh
So it comes to what voltage camera assumes to mean empty battery.


Z740 has some big deficiencies, lack of image stabilization makes use of tele limited, video mode is bad joke/insult, 13 fps and writing speed seems to be really inferior compared to almost anything.
http://www.dpreview.com/reviews/kodakz740/page12.asp
(write time for one image 7 seconds even though those are very(/too) highly compressed and with that speed 5 shot buffer won't help much if you need to take photo every couple second)

Ah. Okay, so that's how it's calculated.
That means, 2.4V x 2300mAh=5520mWh is really thatmultiplied bytwo with two AA batteries used? The cameras uses only one CRV3.

Yes. The Z740 is not anywhere near perfect. But for about 250-260€... I need to pay at least 100€ morefor a camera that has AS or better movie mode. The AS you can get around by having a cheap tripod. And it's notall that often I'm going to be shooting 5x or more zoomed inpictures.
Was thinking about the Minolta Dimage z3, but it seems, it's not sold in Finland anymore. And it would be 50€ more expensive too of course.

Actually NiMHs have slightly higher voltage than 1.2V (when it gets around that batteries are near empty) but that's their stated voltage.

There was also something that after charging CRV3's can actually have voltage over 3.5V. (those use same "chemistry" as proprietary Li-Ion batteries whose ordinary voltages are ~3.5 V and little over 7V)


Looks like price of KM Z3 is same.

I have bought almost everything associated to photographing from other countries... and at least (Konica)Minolta's cameras have entairly same manual nevertheless do you buy it from Finland, Germany or Sweden. (at least with prosumer cameras)

I see. I can get the z740 even cheaper from that site too... But yee, I don't dare buying from abroad (maybe Scandinavia, but not Germany). Has not only got to do with prejudice! Nordic shops are on average more trustworthy, personal experience, and if something goes wrong (i.e. the camera doesn't work) it's going to be a problem if the shop is in another country and speaks only for example German.

And as a matter of fact I haven't got a Visa or similiar creditcard either.
But it was a good tip... for the more daring person.

Here's one shop outside that list. I bought my first camera (Minolta 7i) from them, also other people have good experiences.

There's actually couple central European shops listed here in Finnish price comparison.
http://www.mbnet.fi/hintaseuranta/tuote.aspx/26284

And actually paying to central Europe is easier than to Sweden. (bank transfer inside EMU doesn't cost more than normal bank transfer)

Neither have I.

Not that even many shops in central Europe would support credit card paying.
(UK is different and belongs to countries with obsession to credit cards)

Not a bad price if you ask me... Not all central European shops can beat it.
Always good to pay some tax to our country too!

The minolta dimage z3 would be good for those features (Anti-Shake and good movie mode), but the picture quality is not the best. Many sayingit takes soft pictures. Things like that, and the fact that with this one I can keep below 300€ with camera bag, 256mb memory card and a battery charger (buying the one from Anttila, the lesser brand one with individual charging and hoping that it's okay) makes me take the z740.

And you can't imagine how big of a help you've been with explaining aboutbatteries! Thanks!

Okay... Bought the Everfast charger. 24,90 €. So even if it's not that good, it's not a lot of money.

It does seem to charge at different speeds depending on the numer of batteries. 1

AA=2000mah = 1 hours 15 m

2AA=1000mah = 2 hours 30 m.

3AA=660ma= 3h 34m..

and so on.

To get the best charging, and have the batteries last longest, should I charge only two at a time? Or only one? Faster charging better, eh?

Also, my old Nikon nimhs, say "recharge only with nikon charger". But, hmm, they are normal rechargable nimhs... why not try them in this one?
