Samsung Captivate Extended Battery

I work directly with China's largest manufacturer of Extended batteries. They finished the AT&T Samsung Vibrant for T-Mobile and I've sold a bunch already with 100% feedback on Ebay. Userid is kevinjmoore. Unfortunately, they don't want to make a mold for the Captivate because they don't think there is enough demand in the USA to warrant it. To prove them wrong, I am trying to generate interest so that I can pay for the door mold charge and have them produce a bunch. The battery is the same as the Vibrant so that part is done. It is a 2800maH, which is nearly double the capacity and does last more than twice as long as stock--I know, I have the phone. Please email me at kevinjmoore at gmail dot com to get more details and help us get this rolling. I've reviewed all the forums out there and battery life is definitely one of the top issues. The rubberized door feel is awesome and it doesn't add a bunch of thickness to the phone like you think it might. Total production time is 20-25 days. My price will be at most $40 incl shipping. I may bring it down if demand is high enough. I will need a minimum of 50% fully refundable deposit. If I don't get enough demand in 30 days, I'll refund completely (less $0.30 Paypal fee). Please forward this, tweet this, facebook this and let's get this thing done My communication and customer service is second to none. We are building a US based website that will be up in 2 weeks detailing the over 35 other phones/extended batteries and hundreds of accessories (including IPAD and IPHONE) that we carry.

There is no way I would do that to my captivate. Just make a battery that fits in the factory space that has a 25% more power and i would be happy.

I would do it in a second for double the life are you kidding me! As long as the back cover had some sort of style to it.
unfortunately I'm gonna wait for the seidio 3000mah extended battery.

Ewwwww...
That looks fugly as hell... I would get 2 extra OEMs w/ desktop charger instead...

Doesn't look horrid for the Vibrant. But the Captivate? Yea.. look like a damn camel hump or a hemorrhoid on the back of my phone. No thanks.

I had one on my Dream and other than being somewhat a nuisance for carrying cases/belt clips it was well worth it. In fact it worked so well I sold it to my buddy who had a dream when I switched to the captivate. He loves the damn thing cause he can use his phone all day long now without having to charge it.
I am a someone who prefers function over cosmetics. If it works better but is uglier wtf cares? When was the last time you looked at the back of your phone and was like wow- that sure is purdy You don't interact with the back of your phone. Also with the back being rubberized I would find it easier to rest on my shoulder during long tech calls with clients as I dont use bluetooth headsets. Just this morning I almost dropped my cap as it slipped from my hand getting out of the car- luckily I caught it, but still with the rubber this is less likely to happen. Again.. function over form all day all long.

I carry mine in my pocket. I like the captivate because it's thin. If I need to I'll carry spare battery before I double the thickness of the phone...I'm just sayin'

if i had the battery i could make the dies. are you looking to make a plastic cover or stamp an aluminum one?
anyway it would be nice to have on hand for trips or events where i dont know how long i will go without a charger. i dont think i would walk around with that in my pocket but it would be nice to have one available for occasional use and there are plenty of people that have come around here complaining about horrid battery life. i find the battery life quite good and in an every day environment you can always plan around it but obviously some people want more or just like to complain.

If I traveled, I would be all over this. Unfortunately, the $9 2-pack of batteries with wall charger on eBay just doesn't makes this as economical when I can just reach over and pop in a fresh battery and have the old one start charging.

It adds a "WHOPPING" 6 mm to the phone (not even 1/4"). I gave it to my friend to hold and he said he actually liked the feel better with the door that way. It felt more stable and fit perfectly to how you cradle your phone. The door is better than stock and fits easily in your pocket. It is NOT bulky at all. To not have to charge your phone every 7 or 8 hours if you are a moderate to heavy user is so worth it. I can't imagine not having it or carrying around 2 or 3 batteries all the time.

It is 6mm extra on an 11 mm phone (about 50% thicker for double capacity). It's a no-brainer.

i think you'd sell them but i think this might not be the right forum for it, the less than enthused response doesn't mean that people who travel aren't looking for something like this, it just means that we dont have that many people on the forum looking for this. are you getting feedback on your ebay store asking for it?

Email me at kevinjmoore at gmail to discuss.

Correct me if I am wrong but...
Isn't our metal back plate aid in reception? I thought the antenna was in direct contact with the back plate. Seems to me that a big piece of plastic holding in a big battery would give us signal loss...

no it appears to be grounded not an antenna but i could be wrong i dont know much about cell antenna design. there are two contacts and one goes to the metal chassis indirectly through a shiny plating on the back of the plastic housing. the other goes to the board but i didn't trace it to tell if it went to the points that contact the chassis and plastic cover, electronics today can be difficult trace.
i know some antennas form a loop and it can very well be an antenna but i find that my phone works fin with the battery door removed. also there is no reason a new batery door cant be stamped from aluminum. or lined with aluminum tape.

I assume that you can't have a battery like this and use a case like the Body Glove Mirage? Are there alternative cases that will work with a battery like this?

A better solution would be a silicone case with a pocket for a spare battery. Carry it when you need to and switch when you need to.

a picture (if you have a functional unit) would be a lot helpful...

From my experience with the BG Mirage + the specs provided by the OP, its a definite No. Not with 6mm (50% thicker) but i would applaud anyone who would try it. Who knows, it might actually work out. Now if only Otterbox cases work with ANY extended batteries..........then I am ALL OVER IT.

Evo 4G OEM Standard Battery?

Sprint does not sell the standard size battery. I remember this with the Diamond also. A few years ago, Sprint stopped carrying standard size batteries for their devices to make room for inventory space, or something to that effect.
I am looking for a standard size HTC OEM battery for the Evo.
The P/N of the stock battery is 35H00123-22M
I have been looking around and saw the battery for sale.
I researched other sellers before purchase regarding description OEM, picture of battery, specs, etc.
I stay away from the $3 - $11 batteries etc. as you usually get what you pay for.
I received the battery but the P/N ends in 25M. The price was $29.99
In addition,
- the red wrapper looks to be too small and there is silver showing on the bar code side around the entire perimeter where the red wrapper edges do not meet.
- the water mark sticker is smaller and does not have a black plastic border around it as in the original, although it is embedded in black plastic.
- the type font appears slightly larger than the original
The above are the differences I have noted between this battery and the stock one I have. I have no other stock batteries to compare to. The Red wrapper appears to be exactly like the original. The differences concern me.
At first glance the batteries appear to be the same until you take a close look for comparison.
Do the differences I have notated also appear in other Stock OEM batteries, or are these difference indicative of a non OEM battery?

I have two stock batteries that came with different EVOs. One is the regular one with the wrapper that goes all the way around and the other is the one you described with the silver showing and part number ending in 25M. Depending on where you got it from, I would say it's legit.

Ok. Is the edge where the water sticker is the same as I described regarding the 25M cell?
I got it on eBay but the seller had a 100% rating with 1900 sales and 230 battery sales.
I messaged the guy regarding the issues, and am awaiting a response. I did mention that the cell appears to be a counterfeit, I may be wrong though.
I guess the 22M battery and the 25M batteries have some subtle differences.
The ad showed a pic and description of the 22M battery and I received a 25M which was why i was concerned.
The differences were subtle but enough to make me wonder, which is why I inquired here. It appears there are variances of the OEM cells as you have mentioned.
I have also seen around the web regarding the silver foils showing, etc.
I showed the battery to a Sprint Manager I know, and he thought it was fake, But he has not really seen any Evo 4G batteries anyway, and I showed him my stock battery for comparison, so I take his opinion with a grain of salt.

My water sticker is smaller, and there is no plastic around it, here is a small cutout in the red sticker where the water sticker pokes through.
Just as a warning, there are a TON of fake OEM batteries on ebay. They look just like the OEM ones but they are counterfeit.
I use these batteries. They aren't true 2000mah batteries but they do last me about a half a day longer than the stock batteries. Been using them for 5 months now and I can wholeheartedly recommend them. They are easily the highest quality cheap ebay battery.

Thanks for that. Sounds like my 25M.
I found this on xda regarding the 22M and 25M batteries, but it seems the pics have been removed from the link >>
http://forum.xda-developers.com/showthread.php?t=821173
Here is the link to the battery I purchased. Pic & description is that of a 22m though, which is what threw me off.
From experience, appears to be a solid seller >>
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140441582056&ssPageName=STRK:MEWNX:IT
Edit:
I just took a voltage reading of the 'new' battery and it read 3.42V
I installed it into my Evo, and the red LED was blinking. It went steady after a couple of minutes, and it was at 6% charged. I removed it from my Evo as I didn't want to possibly damage it.
The Li-ion battery I received was in a state of Complete Discharge, and is no longer viable.
New Li-ions are usually received @ 80% of capacity or thereabouts.
230 sold, so maybe I received the bad apple. Hmmmmm.............
I notified the seller and am awaiting a response.

The seller made good on the battery and exchanged it for the 22M.
I also had another 22M on order from fommy.com, BUT they shipped a 25M battery. And this was after I confirmed on the phone before ordering the battery that it would be the 22M version as per the site's pic and description.
I am returning it for a refund, But I am paying the return shipping
They better not charge me a restocking fee, as they shipped the wrong/not as described battery in the first place.

this is the official htc shop
http://shopamerica.htc.com/accessories.htm?prId=37238

Thanks for the link.
Their prices are a little on the high side. There are dealers that sell HTC accessories at a discount. Just finding the right one with the right info is the tricky part.
They don't have the rear cover which I purchased from fommy.com
fommy got that one right at least.

the 22 and the 25 are both legit. the very first EVOs came with the 25 and then they switched to the 22s. I have many of both models. personally i think the 25s are better but im sure its just in my head. you over paid though, you can get them on amazon for about 15 last time i ordered.

I disagree. I bought two batteries that say Touch Pro 2 on them plus a wall charger on Ebay when I had a Hero. They cost me $9 and were shipped here from Hong Kong for free. They are still both working fine. You can now get three batteries plus a wall charger for $11 and free shipping. Hell, for that price I could replace them every year and be happy.

I have an HTC Diamond and I know those OEM batteries can be had for a few dollars.
I was referring to batteries for the Evo 4G at those low prices.

Extended battery - Fake?

Hi all,
I've just bought the extended battery kit for the SII (the white one). It was purchased from Amazon - but I'm having some doubts as to whether I have the real deal or not.
First of all, I've peeled the sticker back and it's dull on the reverse side - however, I cannot find any etching onto the metal underneath as to what the battery might be..? One other thing that leads me to believe that the battery might not be genuine is that there is no 'date of birth' of the battery. It only shows the battery model number, capacity and the serial number. My battery that came with the phone has the battery 'date' on the third line.
What I want to know is is anyone here has the extended battery and you know yours to be genuine, do you have or not have the date of manufacture of the battery?
Thanks.

On mine the date is labeled like on the one that came with the phone.

mine didnt have the date but it is genuine since the packaging is proper legit with holograms etc

Maybe the ones without the date are newer... the oane i have is from 2012

Thanks for the reply..
I don't have a date on my battery but there is a date of manufacture on the box it came in, which is 2013.5.29. The box itself has a hologram sticker and also two Samsung security seals (one top and the other bottom). The print quality of the box isn't exactly fantastic and we all know that holograms can be faked. The replacement cover also has a small amount of give in the top right hand corner which is a little annoying.
I've had the battery in the phone for a few days now and nothing really seems amiss although I have nothing to compare it to.

Battery Case - Too good to be true?

I pre-ordered a battery case on Amazon, but it just seems too good to be true. I cannot see how they can fit a battery that size into that case for that price.
https://www.amazon.com/Rechargeable-External-Portable-Protective-Charging/dp/B06Y63HPCL
5200mAh
$26.99
Very slim and slick looking
Any thoughts? Should I cancel the pre-order or is Amazon reliable when in helping to avoid fraud?

I just saw this, it's not that expensive, please post IF you get it with pictures as to how thick, hand feel, and so on. I'd be very interested in it if it's not going to make my device look like a brick from the 90s.
There's about 5 pages of questions now and there's a LOT of discrepancy between what the "description" states and what the answers from the seller state:
Description: has a kickstand
Seller answer: has not kickstand
Seller keeps saying you can wirelessly charge with this case in the questions, I WANT to know how that will work. I may order this JUST to see if any of the hype is true

It looks monstrously big for the s8 plus

Update: They increased the price from $26.99 to $39.99. That sounds more realistic now. Also the picture is different and it looks a bit more clunky than the original images. Once I get it I will post pictures of it and give a review.

No way that's 5500 is such a slim case, this case is 5500mah look at that fatty https://www.amazon.com/dp/B06ZXYRCKM/ref=psdc_7073960011_t1_B06Y63HPCL

Okay, holy mother of crap, that thing is huge.

I just could never do a case that big...not with phones this size. Holy crap i can't imagine that in my pocket.

Please post feedback when you get it.
It may not be the slickest case but if it does add 5000mAh then it can be a backup plan for a weekend outdoors. There are times when having a battrey pack makes it much more clunky than a battery case, no matter how bigger it makes the phone.

So, let's see what could possibly go wrong:
Third-party company that no one has ever heard of making a battery case that doesn't even agree with its own pictures of the product/product description
Will it overheat? No, why would you think that?
Will it make your phone burst into flames? Why would that be an issue?
Will it actually work as stated? Sure, so many of the cheap knockoff battery cases work just great.
Please do post how this works out for you. Also, make sure you have a spare device from which to call 911 (or 999 depending on your location)

Best power case would be zerolemon when it comes out

Just ordered this one from Amazon. It's in stock and I will get it monday and let you know how it is.
https://www.amazon.com/ALCLAP-Porta...-catcorr&keywords=Galaxy+S8+Plus+Battery+Case

I guess there's one manufacturer that makes all of these cheap power cases for any brand. The price is great but I wouldn't risk an S8+ for a 50$ price difference. And everything above 3000 mAh will add too much bulk. Don't bother and think that it won't look like a brick. I was prepared to order the Mophie but got insulted by their bad marketing moves. Articles all over the web about the release of the legendarry Juice Pack, and all I got was a coming soon warning! No Thanks. As djhulk2 said I would go with the ZeroLemon or the I-blades. Remember these are brands, plus the I-blades adds extra memory, a platform for other modules and Military Grade Certificate.

They should have different size of batteries...maybe 1000mAh, a 2000mAh, and 3000mA

There are numerous choices out there (just from a google search using the terms S8+ battery cases):
https://powerpluscases.com/collecti...-galaxy-s8-plus-battery-extender-case-5500mah
https://i-blades.com/products/galaxy-s8-plus-case-battery-life-memory
https://www.amazon.com/ICONIC-Portable-External-Protective-Charging/dp/B06ZZB2QYC (has a code of 2RADT4V8 for $10 off making the price about $30, know NOTHING about this battery, BGR is hyping it)
https://www.amazon.com/gp/product/B06ZZB2QYC/ (another case with a code HC7VJ26M for more of a discount, again another site is promoting this)
https://www.amazon.com/Rechargeable-External-Portable-Protective-Kickstand/dp/B06Y63HPCL/ref=sr_1_5 (no idea about this)
https://www.amazon.com/s/ref=nb_sb_...+battery+case&rh=i:aps,k:s8+plus+battery+case (a generic search for s8 Plus battery case on amazon)
And that was about 10 minutes worth of looking. There are PLENTY of options out there, just got to be willing to look.

Battery compatibilty and cut out corners

I gave up trying to find batteries that weren't fakes, eventually just bought one on eBay from an honest seller that acknowledged it and didn't claim it was 'genuine'.
This battery is listed as compatible with my i9195 but when it arrives, the top corners (black plastic, terminal end) don't match up.
I can cut it with a knife to make it fit -- does anyone know what that actually electrical difference (if any) I risk by doing this?
I can provide photos if necessary, but since lots of eBay sellers seem to point out this difference so it must be a known thing. What's the difference between the two shapes of battery?
Thanks

just return it to the seller, it's clearly not compatible.

Hello, you can use J1 Ace batteries. Are exactly the same.

I have owned this smartphone since 2014 (2x GT-I9195i and 2x GT-I9195) and believe me I have tested all those other batteries and have always come back with this type (B500BE) because this battery is simply the best
