ANSMANN 2500 MAH LSD?

[357mag1]

Has anybody tried these batteries?

If so do they seem to have the stated capacity?

While i don't know about these particular cells, I have heard that Ansmann is very tight on their labeling with most cells never exceeding more than 10% deviation (new cells of course). You've got me curious!:thinking: although not curious enough yet to spend $18.xx with shipping.
like I said though, Ansmann is a pretty reputable company. They're German, everybody knows they make good stuff (to paraphrase the shamwow guy)

I'll be curious to see what people find out
perhaps next wednesday, after i get paid, i'll take another look around TD and see if there's anything else i can convince myself i "need".

I took the plunge and ordered 8 of them so I should be able to give a review in a week or so after I break them in and run a test on the MAHA.

I'm aware of some German products that aren't top quality, hope these are.

Thank You! I was pondering ordering and found replacement battery pack for one of my SunRocket phones. It was $1 more than 4 of the Ansmanns! And it was a pack of 3 800mah AAA with plug. Uggghhh

I am eagerly awaiting the results.

I don't know much about these particular cells but +1 on what joeparker54 said about Ansmann.

Ansmann released the MaxE 2100mAh a couple of years ago IIRC. There is some test data on these forums that shows the capacity is slightly higher than the eneloops and also that the Ansmann's maintain their capacity better over subsequent charges, although I haven't seen any information on how the self discharge compares.

These new ones are called "MaxE plus" and advertised as 2500mAh.

Last time I checked, all of Ansmann's NiMH cells were made in China.

2850mAh are 2400 real... not serious for me

Not sure where you're getting that information from. Mario JP tested them here. He got 2400mAh to begin with due do the cells not terminating properly but this went up to 2660+ and he was expecting more with subsequent charges.

i have used a CBA II at 1A discharge rating. Mario use a lacrosse BC900 that overrate the capacity and currents of at least 10% (but sometime also 15%)

i have compared my CBA with a DMM multimeter and a robbe RC analyzer and give accurate results, so i consider more accurate my readings.

ah... i have a BC900 too for comparison

Ansmann 2850 cells true capacity is indeed below 2500mAh, tested by CPF members and there are "real" tests too from consumer agencys etc.
Ansmann Max-E rated capacity may be higher than other LSD cells, but in my tests it performs worse than other LSD cells.

I don't believe that these new Ansmann cells are really 2500mAh and LSD.

I've never heard of the BC-900 overrating cells before. I've heard of it melting but not overrating. Do you have any links to that? Are you sure your cells are not just terminating early like Mario's were?

 

[davidefromitaly]

well first of all i consider my tests: cbaII, robbe power peak, various DMM give all the same measurements (maybe 2-3% difference not more), lacrosse is the only overrated

second, you can check all the tests on the net whit common batts, all overrated

third, you can find the posts here on cpf of that guy that work at maha, he say that the lacrosse don't take in count of the pauses in the charge and simply multiply the current for the time, and last it use a inaccurate capacitor instead of a quartz oscillator so there can be differences between variuos lacrosse

just for laugh, when i charge the duracell 2650 it terminate at 2.88Ah while other chargers at 2.5/2.6Ah and it don't overcharge cause the battery stay cool (at 1.8A rate and the battery is in good condition)

There was another thread recently, about a 2500mAh LSD NiMH cell. I don't believe it was an Ansmann, but the consensus, as I remember, was that it was a Yuasa Delta product, as I believe all of Ansmann's NiMH cells are.

La Crosse BC-900 'Surface Charge'...

I've never heard of the BC-900 overrating cells before... ...Do you have any links to that?

Do a GOOGLE SEARCH for keywords (MUST use quotes): "BC-900" "surface charge"

The MH-C9000 'rests' (1 or 2 hours, depending on the FUNCTION) between the CHARGE stage and the DISCHARGE stage, which allows the 'Surface Charge' to 'bleed off', leaving you with the actual capacity available to your devices. Sure, if you take your cells "HOT off the Charger" and begin using them, you'll be able to take advantage of that extra ~5-10%. But, in an hour or so, it's lost.

That article says that the difference between the two is 50-100mAh that's more like 2-4%.

Re: La Crosse BC-900 'Surface Charge'...

Actually depending on usage and how much the device discharge rate that these cells are being used in can make a difference. When new you kind of have to break them in to obtain close to advertised capacity. Not talking right off the charger either. I had these cells sitting around for days to almost a week and was able to get discharge reading of 2625. One time all of the cells achieved 2700 after 3 days sitting.

The only downside to these cells is they can be fragile on HIGH DISCHARGE RATE which took me by surprise.

I say this because I use these cells in a mobile usb charger to charge my smartphone. When I upgraded from my blackberry curve to the new bold 9700. Before it was drawing about 800-900mAh on my curve.

the new bold. Boy did the discharge rate skyrocket. It is now drawing 1.8A continuous discharge rate.

I am finding out these cells can't handle at a discharge rate that high. And the side effects are showing big time. They now have develop high self discharge rate. Just 2 days sitting there 50% of its capacity is lost. Also the voltage under load is way too low that i am having difficult time charging my bold. In fact the batteries inside the usb mobile charger gets way too hot almost to 100F while charging my bold 9700.

To confirm this I decided to charge these cells up and do a 500ma discharge rate.

Voltage readings are not good. After 30-60min voltages on all four cells are reading below 1.2V one cell reads 1.15V. Another thing I noticed is the popping sounds of these cells are getting quite frequent when charging, even at a slow charging rate. And it started to happen more often the moment I started to charge my bold with these cells.

Conclusion. These ansmann 2850 are excellent for charging my blackberry curve 8310. But took a serious beating trying to charge my bold 9700. Surprised that my mobile usb charger handled the bold. Too bad the 4 cells in it did not survive the torture unfortunately.

I don't want to charge these cells anymore, as it keeps popping too much.

These cells are now ruined and was not cheap

This thread is titled Ansmann 2500 LSD. So why are people talking about the 2850 which is non-LSD? :thinking:

Re: La Crosse BC-900 'Surface Charge'...

True sorry but it is related because of the 2500 MaxE whether these cells are LSD, and add to the fact that LSD cells are around 2000-2100. This would be interesting to see.

Why do people continue to QUOTE *ENTIRE*(and sometimes LONG!) posts, even if it's the post immediately preceding their reply, when only a portion of the post is necessary to indicate 'To Whom:' they are replying and about what? :thinking: :shrug:

Because people are different and don't quite do things in exactly the way "you" would do things. Is there some forum rule that I'm breaking?
