Varta ready2use 2300 mAh

[Anders]

Hello.

Just found this new cells here in sweden.



Anyone heard of a LSD cell with more mAh than 2100?
Rayovac is the name of Varta sold in US, can you find the 2300mAh in rayovacs products?
The international site dont have these 2300mAh cells.

Edit: Some readings out of the box:
#1. 1.292V
#2. 1.295V
#3. 1.292V
#4. 1.296V

After discharging on C-9000 @0,5A
#1. 1335mAh
#2. 1427mAh
#3. 1418mAh
#4. 1409mAh

After break in with C-9000:
#1. 2315 mAh
#2. 2312 mAh
#3. 2312 mAh
#4. 2316 mAh
:


The top is black.
The back of the cardboard says, Made in PRC. Nothing on the cell.

Here is the results from discharging at various rates:


As you can see, they dont perform so well above 4A as Sanyo Eneloop does.
2.19 Ah @0.5A
2.17 Ah @1.0A
2.10 Ah @2.0A
2.04 Ah @3.0A
1.99 Ah @4.0A
1.61 Ah @6.0A
0.22 Ah @ 8.0A

Here is the results from Maha Imedion: A after the results should be changed to Ah.


Sanyo Eneloop from my previous tests:
0,5 A, 1.90 Ah
1.0A, 1.85 Ah
2.0A, 1.85 Ah
3.0A, 1.80 Ah
4.0A, 1.79 Ah

I did not perform any tests on Eneloop @6 A or more.

Here is the results from Silverfox thread about Eneloop, he got very strong data from Eneloop at high A:

They are listed under "Power Accus" on the international site.

Different color but the same Varta No. 56726.

 

[Anders]

Thanks Tohuwabohu.

Didn't see that.

[smopoim86]

Made in china or japan?

 

[Anders]

Hello smopoim86.

I did not look for that.
I guess we have to wait 40h or so now

They are in C-9000 again for a breaking in charge.

The reason I was wondering is because of the new made in japan black top duracells. Figured they migh be these.

 

[Anders]

Hello smopoim86.


I'll understand.

However, I can't see what kind of top there is now and I don't want to break the charging for that.

Varta is part of the Spectrum (Rayovac) family.

These would be Made In China.

These increased capacity cells from Rayovac/Spectrum have been rumoured for a little while now.

If these are now popping up in the wild, we should start seeing 2300 mAh Rayovac Hybrid or Rayovac 4.0 cells in the North American market "soon".

It seems there isn't a black-top Duracell made in Japan.

A closer look at the Costco multi-pack revealed that even though the package clearly stated 'Made in Japan', the actual cells inside the multi-pack were labeled as 'Made in China'.

I'm sure this error represents a fortuitous oversight by Duracell, and not a deliberate ploy to take advantage of what appears to be an ever-increasing demand for the 'Made in Japan' pre-charged cells...

 

[Bones]

This is confusing.

According to the Varta website referenced by Tohuwabohu in post 2, their Ready2Use low self-discharge cells are named LongLife Accu and the maximum capacity currently available is 2100mAh in an AA cell.

The following chart for the LongLife Accu also notes that Varta cells bearing the Ready2Use symbol retain 80% of their capacity after one year:



However, on the same website, there are images of four additional cells named Power Accu rather than LongLife Accu that also bear the Ready2Use symbol. These include the 2300mAh AA cell referenced in this thread, along with a 3000mAh C cell, a 3000mAh D cell and a 200mAh 9V cell:



I can't help but wonder why Varta is distinguishing their Power Accu cells bearing the Ready2Use symbol from their LongLife Accu cells which also bear the Ready2Use symbol.

It occurred to me that the former might be a cross between their regular chemistry cell and their actual low self-discharge cell, but I doubt they could retain 80% of their charge after one year as is claimed for all Varta cells bearing the Ready2Use symbol.

Capacity-wise, the Varta 3000 mAh LSD C & D cells align with the Rayovac Hybrid C & D LSD cells available now.

I know with the current version of the Hybrid C & D cells which showed up here earlier this year, they lost approx 18% over 3 months.
I have a set of D cells sitting by waiting for a 6 month self-discharge test, but those won't be ready for testing until November.

 

[TorchBoy]

Just found this new cells here in sweden.
...
Anyone heard of a LSD cell with more mAh than 2100?

Not me, but why do you ask? I can't see that these claim to be LSD.

 

[45/70]

Not me, but why do you ask? I can't see that these claim to be LSD.

I think because they say "Ready 2 Use", Torch.

[TorchBoy]

Just marketing, then. Hm, maybe it's not just Energizer that pulls tricks like that.

 

[Tohuwabohu]

Not me, but why do you ask? I can't see that these claim to be LSD.

On the Danish Varta site and several other country sites these batteries are listed under Ready2Use with the same notes as the LongLife Accu on the international site.

[TorchBoy]

OK, sorry, I'm with you now. Um, marketing? :shrug: And how come I can read it? My Danish is limited to "hej" and "hej hej".

 

[Anders]

Hello, or should I use Hej Torchboy

I edited first post with results after break in an a photo of the top.

There is no information on the cell that tell us where it is made.

Anders

 

[TorchBoy]

Are you going to let them sit for a month or three before another test?

 

[Black Rose]

There is no information on the cell that tell us where it is made.

It should be on the back of the cardboard backing that they come in.

 

[Anders]

Hello.

TorchBoy:I should test them more, a CBA test is planned with different loads.
Eventually a long test as well.



Black Rose: Thanks, I looked more carefully at the back of the cardboard.

Made in PRC.

Nothing at the cells.
