I am also interested in opinions on rechargable AA batteries. But I would be more interested in hearing about which ones are 1.5v vs the 1.2v that most rechargable AA's seem to be.

The best are Powerex 2300's but I would go with these at a fraction of the price (per battery).

Dang, $1.33 per battery, not bad for that capacity. Yes, Nickel Metal Hydride batteries are the way to go. They aren't good though in things like clocks or remote controls, as they lose power just sitting idle. They're good for things that need a lot of power right now, like digital cameras, or motorized toys.

But I would be more interested in hearing about which ones are 1.5v vs the 1.2v that most rechargable AA's seem to be.
The voltage is a result of the chemicals used. Lead acid cells produce 2 volts. Lithium-ion...think those are 3.6V. Alkalines are 1.5, and NiCads and NiMH put out 1.2V. If you need more than that, you wire them in series - more than one cell is technically called a battery. AA's are cells. 9V's are batteries - 6x1.5V cells in one package.

There are no rechargeable NiMH or NiCd batteries with a cell capacity of more than 1.2V.

Powerex, Sanyo, Energizer, GP cells are all decent. The Powerex and Sanyo's particularly doing well in tests IIRC. I'd just pick up some GPs from Ebay and be done with it. They are OEM batteries and work very well - especially for the price.

The real world difference in performance between the top brands is IMO relatively insignificant compared to what you pay for Powerex Vs others. I've seen Sanyo batts at Costco for a very good price too. Go for the most cost-effective good batt out there and you'll be set.

rayovac 15min charge nihms. nothing touches them. turns charging at the last moment into a possibility.

At that speed... how warm do those batteries get during a charge cycle? And related to that, how long of an overall lifetime do you think that they have?

Sanyo 2300 without a doubt.

I know for sure about this because I used to have Olympus D-40 digital camera (D-40 is known for its battery drain problems). I've read various reviews and tested 'em by myself and the best one was Sanyo 2300. Also, make sure you get GOOOOOOOD charger. Charger is more important than batteries.

the charger has a fan. the batteries are special so they can better tune the charge. only the ic3 rayovacs will charge at 15min. lifetime is the same. babying cheap nihms for an extra few charges is rather pointless waste of time anyways.

It depends on the use. I prefer the Pure Energy cells from Wal Mart because they don't lose their charge over time. Their downfall is that you can only recharge them 20 times or so. They last a really long time per charge though, I'm very happy with them. Did I mention that they're dirt cheap?

The Rayovac batts get very warm after recharge, plus side they charge fast and last a long time. down side: they discharge faster even when not in use than other rechargables.... YMMV

those are just cheap reg nihm


and all rechargables lose charge when not in use. 1% a day or so. whihc is why they aren't left around for emergencies

Tom thanks for the links. Can you recommend a charger?

Also how long do those cheap 2250mAh batteries last per charge compared to duracell alkaline which I've always used?

depends on drain. low drain long lasting devices... clocks etc.. = bad. super high drain like digicam, nihm outperforms alkaline.

Sure I'll give it a shot.

I use Powerex 1800's so I can't speak of the quality first hand but I have heard good things about those batteries, I use a charger that's simular to
this one. With my batteries I can take enough pictures(160+) to fill up my 256mb card without having to worry about using the falsh and lcd, in other words those batteries should last a lot longer in a digital camera, mp3 player, etc... than the alkalines.


Good luck,


Tom

That looks like a great deal for $30.
