1000mah AAA Duracells?

[Art]

Hi,
sorry if this is a stupid post but I asked my girlfriend to buy me some AAA nimh duracells that are ussually 900mah and she phoned me saing they are 1000mah now I havent seen them yet but she was prety shure on the phone...
Has anyone tested them yet?
I read sanyo are the best but duracells are also in the top range.

Regards,

You probably want the precharged version, which isn't 1000mAh.

I ve read on another site that the 900mah are no longer made that the 1000mah are the only avaible.

What do you meen with precharged?

Better than the ordinary ones. The only ones worth buying if you are buying new batteries.

What is the difference in this ones?
I understand that the dont uncharge that fast but under use what are the advantages?
I think I never saw this ones on sale...

Thanks

Many people have found that the Sanyo Eneloop versions in particular perform better than other cells. They maintain good performance through more charging cycles over a longer time, and they can supply more current with lower voltage drop in use. Also they are very consistent and predictable, with very few bad cells discovered.

In addition to this, the low self-discharge is a big advantage for many items that are used infrequently, and it also allows you to keep charged cells on the shelf ready to use.

We believe that the Duracell Precharged cells with the white plastic top are the same cells as Sanyo Eneloops in different packaging, and so should be just as good if you can find them.

They have on the site something like 200 fotos with nimh and 5000 fotos (with flash I guess) with this precharged ones?
More then 20times the capacity?

And to charge them , should I use the same charger of the NiMh? My charger is only 100mah for AAA it takes 10h to charge them...

Will try to find them here and test. I was going to buy them for the L0D so 2 are more then enought.

Regards and thanks for the help.

Take a look HERE, the bundled charger charge at either 450ma or 900ma for AAA cells, so you'll be done in under 2 hours.

the 5000 vs. 200 is aganist alkaline, it actually havea little less capacity than other nimh.

Yes sorry its 600 vs 5000 still nearlly 10 times more.

But now you say it has less capacity then the 1000mah nimh? :thinking:

You just confused me for today :candle:

The real capacity of a cell is how well it works in the target application. It turns out that the real capacity of alkaline batteries is very low when used in digital cameras, so when used in the same camera you will get many more pictures from [one charge of a set of] NiMH batteries compared to alkaline batteries.

In addition, NiMH batteries can be recharged and alkaline batteries cannot, so they may claim you can get 5000 pictures from a set of NiMH cells, [but this is] over their lifetime (with many charges in between).

Lastly the actual capacity of pre-charged cells tends to be lower than other NiMH cells, so the Duracell pre-charged will not have 1000 mAh like the other cells. In practice this is not the disadvantage it seems as squeezing more mAh into a cell makes it more fragile, so that 1000 mAh may not last for many charges before you have to replace it with a new one due to premature failure.

Art , I'm mathematically challenged at times also. Usually in the morning before coffee and the kids claim I didn't give them their allowance yet.

Thousands of pictures # from the precharged rechargeables assumes you are
smart enough to recharge them when needed. No need to buy more cells.
Advertising talk. You just fall off turnip wagon? Maybe you like to buy bridge?

Say you complained about your new car, thats guaranteed for 5years/100k miles because it stopped working after only 400miles? And the reason was you did'nt think it needed to have gas put in it.

Sorry. those kind of vague semi true but false claims irritate me too.
cheers

When we dont really know what its been talked its normal to fall in advertising talk but still I did not believe in the 5000 photo "ideia".

But as always as a " bad" advertising Im not convinced so I will end up buy some 1000mah... will see tomorrow it the prechared are avaible.

Thanks

Sorry I meant the precharged version of nimh, while can stay charged longer, it has less capacity than regular version of nimh.

Couldnt find the precharged version here in portugal... ended up buing 2 1000mah nimh.
Did a tested and charged 2 trust 1000nimh and 2 duracells 1000mh for 15hours , then the next day measured and the trusts ones were at 1,360v and the duracells 1,382v... is this a normal diference or are the duracells better ?

If you dont know what Im talking about here is a link:

Were they both new?

Duracells brand new and the other where on their 2 charge...
Arent they supossed to be at 1.4v after charge?

 

[shadowjk]

I'd say 1.35-1.37 or so when you've had them "cool down" a day after charge..

 

[Mr Happy]

It really seems to depend on the specific cells and the charger. For Eneloops, they definitely will stay above 1.4 V for weeks after charging on a good charger. Other cells maybe not. It all depends.

My charged is not very good , it takes 15hours to charge 1000mah... its more less 90mah per hour charge...
Im trying to use 4 of them so I can charge them together and have the same volts to put them into my LL P7... Using the L0D to discharge them so its taking a while one at a time lol

Sounds like you need a good (not timed) charger. That's the key to long, happy NiMH lifestyle.
