oh my lord! How long does that monster last?

It'd be nice if they posted actual pics of the batteries, it seems they've used the same pic for all the aspire one batteries. It'd also be nice to see a pic of it on an AA1. I'll bet it looks like a beast. Maybe that is why they do not show it.

 

Hi Ryan:

Your observation is valid, those pictures look similar.

I'm the store owner, I've changed them with pic taken from a different angle to make the difference visible. At the moment, the picture of battery fitted on the AA1 is not available.

To have an idea of the performance.....maybe you can ask some of my Ebay customers how much juice do they get from 6600mAh

To know the actual performance why dont you buy one and test urself
bEsT!!!
~me~

 

Honestly, I dont know exactly because that depends a lot on the way u use the netbook and the applications u run.

For a quick review of what you may expect from Cameron Sino batteries plz have a look at this review http://www.eeeuser.com/2008/07/01/clove-technology-cameron-sino-battery-quick-review/

please note that this review is for eee pc...it can only show u about the performance of CS batteries

bEsT!!!

 

Hi,

I've ordered this product. Now I'm waiting for it to arrive and will be posting some results regarding how long it will last in real life usage vs maximum stress test and idle. I'll also take some pictures of what it looks like on my One!

 

I'm holding out for a 13000 mah battery in black!

 

the highest allowed battery pack (therotical would be 10400mah, 11.1V before it goes beyond the FCC limitation)

 

Use one of those lead acid battery pack from a regular APC UPS unit.

 

Has anyone purchased this from that site yet?

 

I received my battery today!

I made my order 28.11 and received it 10.12

My battery came from Honk Kong nicely packed in a bubble wrapped letter + carton box with cushioned lining and inside a anti-static bag. Mine was marked as a pda accessory, with a hard to distinguish value marking (I was lucky and no customs extras).

The markings all look good and from what I can tell the quality is good. The battery is quite rounded and has rubber feets plus rubber cushion where the display meets the battery.

It came precharged to 45%. The first information on the capacity is 77933 mWh which divided by 10.8V makes 7200mAh, but this discrepancy might be explained by the fact that it hasn't been conditioned yet. The designed capacity says 73260 mWh, so it's clearly above this number, but will it go above 80000 mWh remains to be seen. It should go up to 84000-86000 mWh (7800mAh*10.8-11.1V).

My digital camera was out of batteries so I'll get back to post those later.

My first preliminary results using batterymon v.2.1

Best possible scenario turning wifi off, display brightness semilow (I have the brightness-plagued version), and minimal usage, using A1ctl to disable LAN, webcam, wifi and custom fanspeed (off mostly)
Discharge rate 7-8 W : runtime 9-11 h

Worst possible scenario, brightness max, wifi on, batteryeater running (processor 100%, using hard drive and display), A1ctl all on + fan on auto
Discharge rate 14-16W: Runtime 5-5.30 h

*I tried maximising the discarge rate later turning on every high performance option in Vista power options + moving gigabytes on the hard drive and using one of those dreamscene wallpapers, I was able to get up to 18.5W dropping the runtime to approx 4.5 h, so this might be the lowest possible (this kind of load would never ever happen for a long time in real use!) runtime.

I'm quite pleased, minimum 5, and probably a lot more.

My model is the A150 with 120gb hard drive, 1gb (without 3g) using Vista Ultimate.

The seller is very helpful and answers emails promptly. My recommendations.

 

doesn't a designed capacity of 73260mwh mean it's a 6600mah battery? (73260mwh / 11.1v = 6600mah)

 

@justme81 thanks for the detailed feedback and positive comments as well.

Please post again after a few charge/recharge cycles. If the manufacturers have labeled it as 7800mAh then it must live up to that capacity. If it doesn't then I'll talk with them to disclose the correct amperage.(or at least i'll disclose the correct amperage on my website)

Best!

Yes, it's all a bit confusing

I think the manufacturer had just rushed it a bit.

Cameron Sino is known to have produced 6600 mAh batteries before. Probably they've neglected to change the reading for the designed capacity (maybe it just has the same electronics board). It definiately has bigger batteries since the fully charged capacity is well above the designed one. I'm NOT cutting it open to check the litium ion cells themselves.

There are 3 alternative 9 cell batteries:

2200 mAh * 3 cells 3.6-3.7V * 3 parallell = 9 cells 6600 mAh 10.8-11.1V = 73260 mWh
2400 mAh * 3 cells 3.6-3.7V * 3 parallell = 9 cells 7200 mAh 10.8-11.1V = 79920 mWh
2600 mAh * 3 cells 3.6-3.7V * 3 parallell = 9 cells 7800 mAh 10.8-11.1V = 86580 mWh
*2900 mAh * 3 cells 3.6-3.7V * 3 parallell = 9 cells 8700 mAh 10.8-11.1V = 96570 mWh* (Theoretical non-existing added 11.12)

This battery probably has the 2600 mAh batteries, but shows the old designed capacity for 2200 mAh cells and unconditioned fully charged capacity resembeling the 2400 mAh batteries.

It is common knowledge that litium batteries take 3-5 cycles before getting up to their best capacity, so I'm not worried. The biggest question is, how long it takes for the electronics to catch up and report the correct measurement.

Anyhow I'm looking at absolutely worst scenario getting 5h of juice and most probably 8+ hours and maybe even 10+ hours.

I might write back to Cameron Sino and tell them their battery reports the wrong designed capacity, although I suspect they are aware of this little mishap.

 

Pictures

The battery construction looks identical to the one in this thread:

viewtopic.php?f=15&t=6730&st=0&sk=t&sd=a&start=30

Since there are so nice pictures and angles I can't hardly come up with better ones. Mine is white though, and the rubber feets are translucent.

The battery surely adds to the Acer Aspire one. The size next to the old 3-celler is huge, but after you plug it in it's easy to forget again, and it does give you a grip too.

The worst thing is, that it wont fit my fancy leather case anymore (maybe I should mod it =)

The best thing is the writing position with this 9-cell battery. The tilt is very natural for typing. The tilt is also good for increasing air flow.

A few not so perfect pics:











Oh man do I take blurry pics, and my sofa is not perfectly smooth :?
Maybe I'll concentrate to take some better ones some other time

 

Reporting! Conditioning of the battery

Conditioning of the battery

Goal: 7800 mAh * 11,1 V = 86580 mWh
Start 7020 mAh * 11,1 V = 77933 mWh
Difference: 780 mAh * V = 8647 mWh
(Designed: 6600 mAh *11,1V = 73260 mWh This is probably a artefact from a previous product line)

My first full charge -> discharge and reboot.

Before: 77933 mWh
Now: 79176 mWh
-------------------------
Gain: + 1243 mWh

So it is definiately gaining capacity!

Second whole charge + discharge. Result after boot:

Before: 79176 mWh
Now: 78721 mWh
-------------------------
Loss: -455 mWh

Battery seems to be a bit confused, let's see where it goes next charge!

Third One:

Before: 78721 mWh
Now: 79876 mWh
-----------------------
Gain + 1155 mWh

The battery went up, down and back up, lets see what comes next. Almost breaking the 80Wh on third charge. Now it has gained ~2 Wh, if it gains 4-6 Wh more it lives up to its specification.

4th full charge/full discharge and boot:

Before: 79876 mWh
After: 79443 mWh
-----------------------
Loss -433 mWh

Looks a bit like a pattern. First the battery gains approx 1200 mWh, and then it loses 450 mWh. So the gain from 2 full cycles is only 750 mWh, or 350 mWh/cycle. Sad, I was really hoping to break that 80 000 mWh mark this round. If this conditioning speed stays the same it will take quite long (24 cycles for mine) before the battery gets up to its specification (86580 mWh - 77933 mWh / 350 mWh ~ 24).

The battery is still huge and is gaining capacity, even if it seems to be doing it slower than I was anticipating. So I'm not dissatisfied, just a little confused. Maybe it is the old designed capacity that is hindering it from gaining that capacity faster. Hopefully some of those, who order receive units that show designed capacity of 86580 mWh and full capacity close to that!

5th time:

Before: 79443 mWh
After: 80986 mWh finally breaking the 80 Wh barrier :mrgreen:
----------------------------
Gain: +1543 mWh

Still going strong, but I must say I expect it to go down to 80500 mWh next time =(

6th time:

Before: 80986 mWh
After: 79498 mWh
-------------------------------
Loss: -1488 mWh

Looks bad, lost almost as much as it had gained last cycle. The pattern is still there, a rollercoaster going up and down. Hard to say if this battery is going to stay around 80Wh or actually go up to 86Wh. At this point I'd say this battery resembles a 7200mAh battery.

7th time:
Before: 79498 mWh
After: 79498 mWh
Gain/Loss: 0/0 mWh

Now it seems the battery has made up its mind about what the full capacity will be. I must say I'm a little bit dissapointed now, since it seemed to be climbing well, already went to 81Wh. I thought it would keep on gaining capacity. Now the capacity is equal to a 7200mAh battery ( 79498 mWh / 11.1V = 7162mAh). I think It has stopped calibrating now, but I'll report if the measure changes.

Either the battery is a mislabeled 7200mAh battery, or it is a 7800mAh battery, that the electronics board is unable to interpret correctly, which results in a loss of 600 mAh. This might be a isolated case, or the norm, i have no way of telling.

Maybe death.hilarious will post a update how his battery turns out.

Deisgned Capacity ?
Unconditioned Full Capacity?
Conditioned Full Capacity?

Everyone else are also highly encouraged to report their findings!

My battery is still quite marvelous, and there ain't anything better to buy. Either get one of those older 6600mAh, or 7200mAh or this 7200mAh (7800mAh?).

 

Thanks for the information, this battery seems to be very promising, I hope your review will continue. We know that the 2200mah and 2600mah cell groups are the standard cells Acer used, and 7800mah 9-cell battery is probably as dense as it goes now. But are there 2900mah cells available, can we expect something like EeePC's massive 13000mah 10-cell battery somewhere down the road?

 

I think this is the highest that's going to be released!

You're hunch is correct. There are indeed 2900mah cells being produced, but I doubt it these are comming to the mainstream in the nearest future.

Like this one: PANASONIC 18650 3.6V 2900mAh/2.9Ah Lithium ion Cell
http://www.ecvv.com/offerdetail/I2397548.html

They are probably going to produce so few and be proportionally so much more expensive, that you won't see them in battery packs. Maybe after 2 years when this battery pack starts wearing and "only" lasts 6-7 hours =)

We are not going to see 10-cell batteries, since the voltage is crucial. Acer Aspire One uses 11.1V and Asus eee PC's 7,2V.

5 * 2 cells 3,6V = 10 cell Asus 13000mAh*7,2V = 93,6 Wh
3 * 3 cells 3,7V = 9 cell Acer 7800mAh*11.1V = 86,6 Wh

The difference in capacity is only 7Wh, or 8% for Asus, and it actually contains one more cell!

There is a small chance we might see that 2900mAh battery * 9 cells = 96,6Wh which would beat the Asus by a small margin.

I doubt we will see the above mentioned. Even more unlikely is that we would see a 12 cell battery (4 * 3 cells), since this format would be so huge both sizewise as weightwise.

I was already a bit apprehensive in buying this 9-cell, since it protrudes both backwards and downwards + adds considerable weight to the netbook. And the whole point of the netbook is to be portable. Then again, what is portability without battery life? Comparing to my 3-cell 2 hour battery I feel my 9-cell 9-hour battery is way more portable :!: :!: :!:

I was considering buying the 6-cell 5200mAh*11.1V=57,7Wh battery. But the original was so expensive and the replacement 6-cell pack was only 4400mAh*11.1=48,4Wh. Considering this 9-cell replacement battery offers 77% more power than the 6-cell replacement battery I went for this one. The price was essentially the same!

8 hours 31 minutes (91%) remaining!

I think that non-intensive tasks such as Surfing, Word, Excel etc will end up in 8-10 hours
Playing movies, gaming or other demanding tasks will probably give 5-7 hours and absolutely minimum being 5 hours (using stress test).

 

I think you have a valid point, using 3 groups of 2600mah cells is probably where the sweet point is, the cost/performance ratio is at best here. I do a few international travels a year so I definitely need something that will last over six hours for me. I ready Ebook, listen to music and watch recorded QVGA resolution shows on the One, so I think even the 6600mah battery can handle that, considering that I'll use A1Ctrl to disable Wifi, Ethernet, Webcam and dimm the LCD all the way down. So far the biggest downside is the absence of compatible sleves, now I have to use a 12.1" laptop bag to carry the one with extended battery.

 

Re: Sleeves would be nice!

Yup, please tell me if you locate something that will fit this monster nicely =)

I have a really nice leather case, I wish they'd make a custom fit leather case for this niche market !

 

I think if you use macro focus the pics will be sharper, anyway, speaking of the case, it'd be cool if there is a piece in the back that can be unzipped to allow the 9 cell, and when the 3-cell is used it is zipped closes nicely.
