and comes the extended battery?!

While my jasjar is walking through the graveyard, seeking a way-out, with its lcd leaking like crazy, I was checking out the accessories at eBay.
There are extended batteries listed on eBay.
Search text:::
* jasjar extended battery
* jasjar spare battery
They mention:
*Rechargeable and removable power
*Xda Exec/T-Mobile Mda Pro/i-mate Jasjar/Qtek 9000/Orange spv m5000 series compatibility
*Extended 3000 mAh
*Easy installation
*CE APPROVED
About ~27 pounds each (battery & extended backcover).
So it looks like it will be a whopping 1620->3000mah jump... almost double the charge capacity
Any comments on these items? Has anyone tried them already?
- Matt

I have one of the 3000mA ones. Works fine. Adds bulk to the unit though.

I also have the 3000mah thicker battery with battery cover..and I must say that I'm quite impressed with it so far. It obviously does add to the size but as I dont usually carry my exec in any type of case it doesnt bother me, however I do use a screen protector as I keep the unit in protrait mode normally.
Definatly worth it if you can handle the extra thickness.

Would you post a few real real life pics of it?

Where did you guys bought your extended batteries? Are those the ones from Mugen Power? Pictures please.

Buying Battery via....
Hi all.
I found this website.
http://www.batteryupgrade.com/quickstart.php?keyword=o2&gclid=CISswqDchIQCFRVrDgodeDn3jw
I think, we can buy Extra Battery for Universal from this Net Shop.
But I didn't try it yet.
How do you think, is it Reliable?

Thanks for the link.
Here is a direct one: http://www.batteryupgrade.com/produ...98&PHPSESSID=2eb7a0b635fbf964f5d5e31df30bec6e
But there was no picture nor mention of any added cover.

Cap?
It is written "imate JASJAR Cap Battery"
What is "Cap" means?
Is it possible about Battery cover or some other?

This is the battery I want: http://www.lionbattery.com/description.php?noproduit=324
I have an O2 Exec and it would look weird if I had the I-Mate back cover. Plus this has more capacity. Anyone have this yet from Mugen Power?

Do you know some device to charge the battery of the jasjar without to be into the pda, I mean directly

Sorry, up to now I have not seen nor come accross anything about a battery charger for our Universals.

I'm interested to purchase an extended battery but I would like to purchase in the some place where some of you made. Could you tell us where did you purchase ?

Yes, too much. It's the price of another phone. But nothing can beat the 4800 capacity especially for long trips, and the back cover matching my O2 Exec.

Bought mine from here

CHEAP!
Imagine putting 4 2500MaH rechargable batteries in it = 10.000 Mah extened Battery + charger.
Connect it when you don't use it, and you always have a full Universal to use.
Also you can buy the batteries in every store in case you need it.

Thank you for your email.
Take a look in this information. It is really interesting but I have not information about quality or security on purchase, do you know this shop?
The following batteries are also suitabel for the iMate Jasjar:
1750 mAh
(http://www.batteryupgrade.com/product_detail.php?productId=28712338 )
3150 mAh
(http://www.batteryupgrade.com/product_detail.php?productId=26539598 )
(the second battery is slightly larger that the original, but comes with an
extended cover which fits your PDA).

i just received a 3800mAh expanded battery from expandsys. ii wanted a 4800, but i didn'tthink it would fit any of the cases i have around, this barely makes it. it's black, and the cover and battery and intergrated together. it's very nice, even thought my PDA unit is silver it give it the two tone that matches the speaker. oddly they don't seem to offer it anymore; the total. price was 91.95 including tax. and shipping.

Best Battery for prophet

Looks like my main battery for O2 XDA NEO is dying, maybe WM6 is eating more of my battery power. Now I want to get a replacement battery. Besides the factory type isnt there a newer version and holds more charge too? Not sure about reliability, if anyone can share some of their experinces will be great.

i dont know however i saw i nice battery on ebay with 1800mah!

Batteries with Extanded Covers ... THEY SUCKS!
The Cover is crap!
The 1800mAh isnt easy to find ... i think its the best Batterie in the moment. If HTC make a extanded batterie kit ... buy it! I have a Startrek with new Coverer and the Quality is very high!

Do you have a link or a pic of the battery? why the extanded covers sucks can you explain that?

you destroy your phone's beauty and also many times the covers are not exactly the same color but enough in order to see the differece also many times they dont completly fit

true ... true

My friends and I are using the 1800mAh batteries from this seller http://search.stores.ebay.com.au/SO...dgetsQQfsooZ2QQfsopZ2QQsaselZ30323434QQsofpZ0
Comparing to my one year old 1200mAh original battery the results were obvious. I could get more than 90 hours of standby with a few mins of call each day. Something I couldn't have thought of with a PocketPC phone.
It's been about 5 months since my purchase, the battery is still good. I heard from others that non-genuine battery tend to have shortened lifespan in just a few months.
Only about 3 to 5 grams heavier and 1mm thicker (which leaves no space between the back cover and the battery) if you do notice these minute differences. It's crucial that the battery won't make your Prophet any thicker!
My only complain was, if you asked, that it took almost a week for the delivery. Otherwise I'm happy with it.

Maybe WM6 has some bug that is draining your battery so much. I have 1200mA battery and it works 4-5 days before recharging.

I don't know, but the best one out there is 1300 i find on eBay... or does Battery for Dopod 818 fit?

Good Battery
For everyone that's looking for an extra battery, look at http://www.dealextreme.com/details.dx/sku.6398
only $5 with free shipping world wide

maybe 2400
ebay

Th 2400 is one with a modded case.
Just ordered 2 battery's @t dealextreme

just took delivery of one of the dealextreme batteries, put it in and no sign that it is charging - battery monitor says "unknown", no orange light or % charge shown. Is it dud or do I have to wait a few hours......?

update, I have 2 of these 1800mah batteries and each behaving same - they don't appear to be charging. Any wise words?

@roughneck57 : sorry to hear.. especially after purchasing 2. does the battery heat up at all?
i ordered one.. and i'm still waiting for it to arrive. now i'm worried.
have you contacted extremedeals, how are they handling it ?
best of wishes,
~ truffles

so far, can't complain as they appear to be sending replacements - and i asked them to check before sending - see below second email I have received regarding the matter:
Thank you for contacting DealExtreme.com Customer Support.
We will make sure the qulity before we send it.
Please feel free to let me know if you have any other questions.
Best regards,
Tiffany
DealExtreme.com Customer Support

forgot to say, battery is not heating up at all - I left it on charge for 3 or 4 hours last night and nothing - however, residual charge is actually powering the PDA so there is life in there. Must be the chip that reports on battery condition and charge etc.
Also, I have tried both in 3 different PDA (m600's) and same problem. One phone has an 1800mah battery purchased from ebay and that looks exactly the same but works fine - so it's not as if the PDA can't handle non-standard size.
Hope this helps.

2430mah stock size gold battery???

Hi,
Was wondering if anyone has tried one of these.....
Its 2430 (or 2450mah) the ebay page cant really decide, im guessing its a typo.... Its the same size as the default battery. Thats a calculated 47% increase in battery capacity...
Link here:
http://www.ebay.com.au/itm/110750637282?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
Its the biggest battery capacity i can find without increasing the physical size of the battery and requiring a new case....
If not, i will post some of my own reviews once it comes through.

Ya i'll bet its a typo, more like 1450mah rather than 2450mah. No cheap aftermarket battery can even match the stock battery in capacity let alone offer 50% more capcity.

im not expecting a full 2400mah out of it, more like a 2100mah....
thing people need to realize, is the stock battery is made in the same places (sometimes) as these after market batteries. The quality might be slightly off, but not substancially..... they are all made in asian countries for less than $0.20 a piece in mass production....

You'll be lucky if it even matches the stock battery, you just can't magically cram more capacity into a battery. The samsung 2000mah battery is thicker and comes with a new cover, why isn't samsung using this battery if it has more capacity and is smaller than its own 2000mah battery? If its too good to be true(on ebay) it probably is.

probably the same reason why they dont release ICS 4.0 and other things straight away that other phones have that is better than what they currently have..... coz they are slightly retarded as a company lol

not a chance that has more power than the stock battery if its the same size. Those gold wrapped batteries from ebay always get really bad reviews. Youll probably find its 1300mah

Seen one review where it was a smaller battery in a plastic frame. Battery capacity was much lower than the stock battery. If it sounds too good to be true and it is cheap, then it probably is.

...are you serious? it's a proven fact that non-OEM/aftermarket batteries in general are usually worse than stock batteries. check out sites like http://batteryboss.org/ you can see testing of aftermarket brands like seidio and mugen...the actual capacity is between 55% to 85% of the advertised capacity, while OEM batteries are ~95%+.
as for what you said about samsung being a retarded company and not releasing the best hardware/software possible, you'd rather trust a random ebay seller with an UNBRANDED battery coming straight from china for $14 aus dollars, which is somehow still 47% higher in capacity, over a multinational corporation with trusted suppliers who are industry leaders in their own right? you really think samsung would willingly reduce their battery capacity in light of the huge implications it could have on the sales of their flagship phone?
as a final piece of evidence, here's a google translated website showing the testing of so called ebay '2430 mah' batteries. http://translate.google.com/transla...e/samsung-galaxy-s-ii-2-3500-mah-2430mah.html as he shows halfway down the page, the real capacity is somewhere between 1000-1250mah. terrible. you should research more before you blindly advocate for your misinformed purchases. all it does is drag other gullible members of this forum down with you.

Different material can make a big difference.
I know it's probably bull****, but i bought one of those battery and i was impressed by the time it last. I tought i would end with a smaller time than stock battery, but it lasted longer. I did not made super precise test, I don't have time for that. I must always be with latest rom / kernel so flashing a new rom or kernel a day don't let me much time to bench battery xD. My point is, that i think it last longer than original samsung battery and this, even if people are doing test that proof i'm false.

Guys you're all being very unfair.
This is obviously a Global Dynamics battery, I believe the model is 'Fringe'. It actually draws it's extra power from a trans dimensional link and was invented by Dr William 'Pointy' Bell.
I'd suggest everyone buy one.
The next version includes the facility to phone yourself after the final race of the day and tell yourself the result before it happened.

So this means the advertised battery should have a capacity between 1336.5 and 2065.5. So one could be lucky and really get a battery with more capacity than the stock one.
Sure, I agree with you that such cheap battery can't hold that much juice. However for a spare battery it is fine if you look at capacity/price.

Typo is an abbreviation of 'Typographic Error' and the phrase originates from when newspapers were printed using printing plates as against computers that are used today.
An example of a typo would be writing h3llo rather then hello or 1243 rather then 1234, it's usually a mistyped character instead of a spelling mistake.
Hope this clears it up for you.

True, but I also did mention that another site tested the capacity specifically for the ebay '2430mah' batteries, and came out with a total capacity of 1000-1250mah. Even if we take it as 1250mah, that's still a 25% decrease from the stock capacity of 1680mah, which is abysmal. You could argue that it's fine as a spare battery, but at that price and capacity you might as well just buy another stock OEM battery, and save yourself the frustration. However, I would definitely argue against using it as your primary battery, for obvious reasons.

Any GOOD suggestions to a STOCK size battery with BIG capacity, that WORKS? Or battery similar or better than Samsung's 2000mah battery?
I use mostly clear TPU cases. Thinking of cutting hole in battery cover for a bigger battery too.
I wish battery covers like those in the 2000mah extended battery kit could be bought in colors, cheap. And then get some nice battery.
Sadly all those mah ratings can't be trusted

No such thing, its either the stock samsung battery or the larger 2000mah samsung battery, everything else is going to have lower capacity no matter what the label says. Check out http://batteryboss.org/ and find an aftermarket battery that has similar capacity as an oem one... there simply isnt one.

[Q] Regarding 3500mAh battery!

Hey guys I just saw a 3500mAh battery for SGS2 on ebay. Is it safe to use such battery? I mean it won't harm the phone, will it? :O

Probably won't harm the phone, no.
I bought a 3500mAh obscurely branded Chinese battery in mid-December. Tried it out for almost two weeks, a bunch of charge/discharge cycles & estimated its real capacity was around 1900mAh. It also used to heat up a lot on recharge (mid-high 40's Celsius, which isn't normal when the phone isn't being used whilst charging).
I took it back, got a refund & bought an original Samsung 2000mAh battery. Hasn't missed a beat, is obviously close to its advertised capacity given I get around 20% more use out of a charge than I do with a 1600mAh battery.
Obviously your mileage may vary if you buy one of these (you might have a better experience than I did), just thought I'd let you know about my experience.

I have one of those I got from DealExtreme and it is great. It lasts 2x longer than the original Samsung battery.
I take care not to swap them often, because I am afraid that this action might damage the original cover, eventually breaking it.

Battery Life
I am still using the 1650 mAh battery (stock) for my S2.
I am really facing some battery issues. Its charging almost all day !
Yes I am using 3G all day and WiFi HotSpot too. But use wifi at home. Thats when I get good battery life. Any better way to conserve some battery ?
Any tips might help
Thanks

Got mine a few days ago from eBay and its been fine so far. It last more than 2x the regular battery. Phone does not heat up or anything strange..
Sent from my GT-I9100 using XDA

well i an getting with the original battery 24H of usage.
with the 3500mah i am getting 60H of usage... so my 3500 is truly 3500mah!
the language is hebrew.
i use congnition rom 1.51 and siyah kernel.

So, where can I see a trustful review on batteries for SGS2? What is the most extended one?
It's really frustrating that my current stock battery is only enough for 2 hd video view (4-5 hours).
Also, the higher the mAh value the more battery lifetime is, right?
I would really want to buy 3500 mAh, but it costs so little.
And the official Samsung variant that offers the longest lifetime of a battery for SGS2 is this one, maybe Mugen 3500 mAh is the best choice out there?

What is the model name of the battery? Is it being overheated in comparison to stock one?

why should it overheat?
it is lithium ... same same

Yes, it's special lithium from China extracted under full moon and blessed by a thousand virgins
Really now, if it was possible to manufacture a battery having more than double the capacity of the stock battery while taking up the same volume, don't you think the megacorporate Samsung would buy that technology immediately in order to use it themselves ? "Too cheap to be true" is valid even here; most knock-off batteries either are fake ("9999 mAH SUPER EXTRA" sticker over the original rating), or will degrade quickly in time leaving you with a dud.
Since there are already fake electronic components...
... why not fake and cheap batteries too, certainly seems to be a high demand for them.

a. it is not the same volume! in is twice as much as the original.
b. the i9100 has a circuit that allows a slow stable charge rate so i dont think it will damage the battery.

As well as being made of inferior materials, not being subjected to the same QC, not having the fuel gauge chip present in original Samsung batteries, you pretty much get what you pay for.
My advice would be to avoid non-original batteries altogether, and given a 2000mAh original battery will cost around the same as one of these 3000mAh+ batteries with all their problems & poor life, it's a no brainer.
Stick with Samsung batteries.

fuel gauge chip?
i would like to see that chip in an any cellphone battery please.

If you're not aware of/don't know about the fuel gauge chip in original SGS2 batteries, you've probably been living under a rock since the phone was released

there is no chip in the battery that is in charge of the fuel gauge.
furthermore there is no use of recalibrating the battery in out i9100 model.

Ecell Gold Battery 2680 Mah BA750..!! Is it real ??

Guys, I found a seller on ebay india selling a ecell Gold battery of 2680 Mah capacity and it's not even so thick like other high capacity batteries!!
The following is the link:
http://www.ebay.in/itm/Ecell-GOLD-2...?pt=IN_Mobile_Accessories&hash=item3f1c9344fa
I wanted to know if this is for real or some scamster company manufacturing cheap unhealthy batteries....

If you search google, you will know they are fake! Just divide the figure by 2 and it is about right! If it is not expensive, you can try one, it won't explode if used properly!!!!

Momax 2700mAh isn't fake. The thing with those batteries is wrong reading, on Momax you stay on 0% for hours and don't know how much is left but it's still double length battery life.

A simple Kernel patch can solve the wrong reading (need unlock bootloader and custom kernel). I allready had done this before for testing purposes.

Oh, I thought it didn't work .

most definitely fake. I purchased one of these before and they were exactly the same as the one that came with the phone

Keep in mind that 99% of aftermarket batteries are Li-Ion, whereas the original battery that comes with the phone is Li-Po.
If you're looking for a Li-Ion replacement battery, you'd want to get one that's higher than 1500mAh as to get a comparable/better battery life compared to the original battery.
With these super high capacity batteries, as stated, you'd need a kernel patch and/or battery recalibration to really get the most out of them. I haven't done this with the Arc (yet), but I have with my previous phones. If you're willing to give up the thin-ness of the Arc, you could potentially have a really decent long-range media device (etc).

Try checking ecell reviews over Amazon, they have very few buyers and ratings varies with each product..
I once bought a smartphone cover from e_cell on ebay, then i found a much cheaper alternative of the exact same case from chinese seller on ebay and dealextreme. I believe these batteries are generic and probably the dudes over e_cell just import chinese toys and sell them at a higher pricetag.. If not mistaken, i think i bought some replacement battery from e_cell for my psp slim, the results does not reflect the printings on the battery at all.

I have the battery which i bought from amazon and it works really good.

Yes, it is real. I have a BA700 which is 2430mAh (for Xperia Pro). I bought it from ebay.
