hey everyone is sanyo 2700 still the best aa?

[raggie33]

i ran thru search and saw silverfoxs runtime chart.and it sure looks like the sany0 2700 is the mac daddy of aa nimhs is it still the best?it will be used in a digital camera that eats batterys like crazy.also what the best charger

Hello Raggie,

If I were in the market for some 2700 cells, I would take a good look at the Powerex cells from Maha. They come with a warranty that may come in handy should the cells develop high self discharge rates.

As far as chargers go, get the C9000, or if you have lots of extra funds the Schulze Next Gen.

cool thank you.ill check em out.and thank you for ya kick but runtime charts

Hello Raggie,

Here is where the 5 year warranty is mentioned...

Powerex AA all the way . . .

I own both and would highly recommend the Powerex 2700 cells. After a few uses, my Sanyo 2700 cells developed a fairly rapid self-discharge rate.

I bought a couple sets of Powerex 2700 cells within a year of each other. Both sets have capacities between 2700 and 2800 mAh (Refresh/Analyze mode on the C9000) and have slow self discharge rates.

Re: Powerex AA all the way . . .

if you can make do with less capacity off the charger MOST people are MUCH better served by a pack of LSD cells (like eneloops) as they tolerate the way most people want to use NIMH cells much better. Lower initial capacity is the tradeoff for a cell that holds the majority of it's charge for long periods of time (I think like 70-80% remaining after a year in storage). They also seem to be more robust, they are probably less likely to develop voltage suppression and they don't seem to NEED as much maintenance cycling as ordinary cells.

How do you compare the AA Powerex against the AA Eneloops. Ok the Powerex has got more mAH where as the Eneloops mAH is 2000 for their AA battery compared to Powerex's 2700. Obviously the run time in hrs on the Powerex will outlast the Eneloops by a bit but the Eneloops have an adfantage of having a very low self discharge rate, which would mean they will take much longer to get depleted over a long period over the Powerex will. So to me they both have their pluses and minuses.

Also will the Powerex AA's charge in the Sanyo Eneloop charger ?

There are several different Sanyo chargers out there: the MQN04, the MQN05 and the MQN06 for four cells, and a two cell travel charger too.

I noticed in Wal-Mart at the weekend that the MQN04 charger was being sold in a package with four Sanyo 2700 cells, so would I assume on that evidence that the MQN04 can handle 2700 mAh cells OK. I think someone here was reporting that the MQN05 did not fully charge 2700 cells though, and that it needed two passes?

 

[Albinoni]

I've got the MQN04A.

 

[raggie33]

well i ordered it. and batts.man the energizers i just bought are 2000 mah and they stink.

 

[Wicho]

That would be me that made that post. Reminds me I need to go update it.

How much did you pay for your 4 2700's and charger at Wal-Mart? I've never seen those there.

Now you've got me thinking about it, I believe it was actually at Fry's rather than Wal-Mart. This item, in fact: http://shop4.outpost.com/product/5208637

Looks like it was $16.99 if the in store price is the same as on-line. I didn't buy, just noticed it while looking around.

To answer the question posed by the thread title... no, the Sanyo Eneloop is.

Check out the Ansmann 2850. I havent seen any tests on them but I know Ansmann tend to rate their batteries quite conservatively.

They even have their own LSD cells.

I think powerex is best. In my lights I have switched from Sanyo to Powerex with better results. Powerex comed from Thomasdistributing.com
Here is a comparison on AA, you should browse through the links, site is not always easy to navigate but the Powerex wins.\

[raggie33]

so far im just very confuseed with it lol.but i like the display.i got it with my 2700 powerexx .i choose break in then i entered 2700.im not sure if i did it right.but i think so

 

[greenLED]

So, am I correct in thinking that the problems with capacities surpassing 2400 mAH have been solved? Or is this a brand-dependent thing?

Going through the site I listed
http://www.rechargeable-battery-revi...eryPerformance
it looked to be not only a brand-dependent but model dependent. Powerex AA 2700 seem to be under rated and that is unique just to this one model. Powerex 2400 were on a par with all the competitors. I have not seen anything suggesting that the 2700 accross the board was now the new standard. I think we have seen some new and innovative batteries come out in the last 18 month. I find a lot of good information on batteries from www.rcgroups.com.
I can say that the Powerex AA 2700 performed similiarly or better than the GP 2000 I had when put up against 5 amp bulbs, 5761. It may be the red herring of the 2700s, it just works well.

The Powerex 2700's have been out for quite awhile now, I wonder if there is anything better on the horizon? I've been thinking of replacing some 2500's with them. They'll be used right after charging and have a near 2amp drain on them when in use, so low self discharge is not really an issue as much as capacity.
