extended batteries from ebay

Hello!
Have anybody tried batteries for Kaiser, that are sold at Ebay? They look cheap and capacious.
http://search.ebay.com/kaiser-battery_W0QQfromZR40QQfrtsZ0
for example this one:
http://cgi.ebay.com/2800-mAh-BATTER...ryZ20336QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Thanks

I have that one and its quite good, needs to be taken out at half charge or whenever as the phone thinks there is no power left.

How is with GPS? Does it works with this type of batteries? I have heard that there are some batteries that blocks GPS signals..

I still get GPS just fine, I haven't had any problems at all with it, yet....

Thanks, so I'll take it

I bought the same battery and it does not fit my TILT. The battery is too thick for the included battery cover. They want me to send it back to Hong Kong. I am awaiting email to see if they will reimburse the return shipping. Beware.

wow, thanks for reply, but I already bought it (for kaiser) strange - maybe there is a difference in batteries for TILT and for KAISER

Nope! Battery in link to eBay will not work with the Tilt!
Kaiser is the universal name for the phone! AT&T calls it the tilt! HTC subscribers [I believe] call it TyTN II. Feel free to correct me if I'm wrong!
^^(aztilt) I'm surprise they are allowing a return and refund, since they are in Hong Kong and the reason for a return is 'incorrect battery' right?
This battery http://forum.xda-developers.com/showthread.php?t=350254 seems to be a great replacement for all others! Post #73 lists an estimated life increase! BEWARE: I believe company is still fixing any bugs/problems!

Their ad lists the Cingular 8925 which is the AT&T TILT. They are allowing a return and a refund of the return shipping cost. But, for $20 I am going to just keep the battery as an emergency backup. I don't need the cover to use the battery. I also found out that i can carry two standard batteries under the extended battery cover so that what I am doing now. I just have to open the cover and swap the battery if I need to. This way I will always have a spare backup battery with me.

The battery is bigger. You need to install a different battery door cover. If you search ebay they sell the extended battery door cover. Most sellers include the battery cover replacement cover for extended battery when your buy the extended battery. My guess is that you probably tried to save a couple bucks, and ended up with the cheaper item that didn't include the cover

The problem is that you can't read or don't want to look at the pictures I have posted in this thread. I got the extended battery replacement cover with the extended battery but it will not fit on the TILT. I was able to use that extended battery cover to carry two standard size batteries with the phone.

Just received battery - it fits perfectly, maybe its a bit smaller.. Haven't still tested out - because it has to be charged for 10 hours, before use..

Like aztilt I got the wrong battery/cover combination from that ebay seller (ukhitech). They offered a full refund (except shipping I guess) if I send the items back but I am a bit confused why they seem to send out the right battery/cover combination to some people but not to others. I bought my battery in May and didn't know then it wouldn't fit since I bought my AT&T Tilt later on.
The battery I got was 13mm thick and for P4550 Kaiser and the cover had a small hole for the camera so it was not the cover that can be seen in the auction picture.
I am curious to know how thick is the battery you have kpcz? And how does the cover look (large or small camera hole)? And you have an original HTC Tytn II and not a AT&T Tilt, is that correct? (Not sure it matters)

high capacity battery?? what vendor? what model? what capacity?

Hi everybody.
plz someone can help me to find a good battery in ebay for my kaiser?
I read about some batteries with high mA capacity but the same performance than the original battery, and some vendors and very bad quality batteries.
so I'm a little bit confused, I want a battery with better performance than the original, but with the same size (of preference) or not too big.
if someone can tell me about a good vendor and his best battery model I would be been thankful with him
PS: plz don't burn me by open this topic so vitiated.
Ps2: sorry about my english

I'm using this battery which is technically twice the capacity here:
http://www.superetrader.co.uk/htc-t...lacement-extended-battery-2700mah-p-3052.html
It comes with a new back casing because as you would expect it is literally twice the width of the original battery so it sticks out at the back. I haven't had any problem with the quality of the battery, but the casing does feel a little bit cheaper than the original.
This one comes with 12 months warranty, which you are unlikely to get on Ebay so bare that in mind when you do your purchase.

Technically, yes...but in normal use, does it actually work? Does the battery work longer?

ive used an incredibly similar style of battery for an older htc phone. I used a battery with twice the mah but didnt quite get twice the life. dont get me wrong, did the job at increasing the life pretty well and u get used to it sticking out a bit on the back
ps, if yer using a tight carry case then it may not fit in with an upgraded battery

that is exactly my question. in this case, which battery is better in weight/size/mAh/performance?

Im using the 1600 mah from www.seidio.com. Barely adds any weight compaired to OEM. Batt life for me is extended about 4-5 hrs. On OEM, with normal usage, I am down to 30% by 10pm (I charge overnight 12am-5am). With the 1600, I am about 45% at 10pm.
All my products from Seidio have been solid. I would stray away from batteries bought from ebay. I got lame ones several times when buying batts for other phones, cameras and devices.

I forgot to add that the 1600 does not need the extended back cover. It is the same dimensions of the OEM. Also the 1600's weight is, if anything less then the OEM. The metal bars/frame on the OEM battery is not there on the 1600. Some say that the metal bars are for reception. So far I have not noticed any reception decrease nor interference difference.

I live in Chile (southamerica) in the ass of the world.
the only easy-fast way to buy something is ebay
I am so lucky I guess, I never had a problem buying this way always looking the vendor feedback/reputation.
thanks by the advice

I think the best battery is that http://shop.eten.hu/mugen-power-300...5-cingular-with-battery-door-black-p-207.html

Why do you think that? Have you compared it to the other extended batteries (including the cheap ones on eBay)? As far as I can see, they're all pretty much the same.
As far as I understand, all the extended batteries have the problem where the Kaiser incorrectly reports the capacity and shuts off when they're half full.
Have you seen this post? http://forum.xda-developers.com/showpost.php?p=2097942&postcount=48

FWIW:
We have few older htc phones at home (ipaqs, tytn1, tytn2).
I bought extended batteries for ipaqs in the past - original from HP's store, and 2600mAh and 2400mAh "generics" from ebay.
Contrary to what I've been "warned" by some people, there was no problems whatsoever with any of the "generic" batteries - they didn't explode didn't damage my phones, nor didn't malfunction prematurely either.
The 2600mAh made in China lasted me 1yr 3mths before it started to act up, the 2400mAh Taiwan-make still works (its been 1yr 5mths now) - and both are no-brand cheap batteries from ebay, and the HP's expensive extended batt (IIRC it is mere 1800mAh only) still works too (almost 2yrs now).
The only problem I had with the extended batteries were their replacement back covers.
Except for HP's original one (of course) which came with 2 extra covers, the "generics" came with really shoddy and crappy covers, the China-make one was the worst: it was slightly out-of-specs, and it always felt somewhat loose (no, it never felt off nor unlatched itself but it had this "loose" feeling always, you could physically feel it moving a bit up and down when holding the phone, not much - maybe half a millimeter - but it was there).
The other Taiwan make battery's cover was perfect in its dimensions (no "loose" feeling) but then its color was few shades off of the original color... not really important detail (specially when you pay 3x less than for the "original") but I thought I should mention it too.
I have just ordered Mugen extended battery for my TyTN II.
When it arrives - and I won't forget - I'll post here about it.

****, I am really confused now
thanks justdave by the advise.

just get a ebay cheapo
http://cgi.ebay.com/EXTENDED-LIFE-B...ryZ20336QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
this is what I ordered. from this seller. battery cover fits perfectly. no wiggle. battery lasts all day without worry with heavy usage. talk, email push, web, im on it all day.
It does not report the battery meters correctly as with all extended batteries as noted. but this battery at 23 bucks shipped is the so much cheaper and I am betting the exact same cells as a seidio or muggen battery. they are all made in china anyways.

An alternative may be an external USB power pack. I use one of these and top up when my battery is going low. Saves the hassle of a larger phone, and all i need is a standard mini usb cable
http://www.proporta.com/F02/PPF02P05.php?t_id=2725&t_mode=des

I am also using the seidio extended life 1600ma battery, i used to charge my phone every night because id be down to like 20% after a day of use, now with the 1600 i go 2 days of use and charge it the 2nd night almost always. Also you retain the original battery cover. I dont know about you guys but this phone is dookie enough as is, i dont need a big battery that requires a new cover and makes my phone another 1/4 inch thicker. seidios a good buy imo, little pricey but ive been happy with its performance.

Extended Batteries
I have an Electrospan by Boxwave @ 2600mah and a Mugen 3000mah. Yes, I think the Mugen might be a little better, but what is interesting is the batteries are exactly the same size although the back covers are different. They do make the device thicker, but it still fits in most horizontal leather cases I have tried. Boxwave also sells an external battery pack that takes 4 AA batteries. The key is to minimize battery drain in the first place. If your data like connects to 3G, battery life goes away quickly vs. edge or GPRS. You can restrict this by using Bandswitch # www.commmgrpro.com (10 euros). Voice calls, screen brightness and push email can also contribute significantly to drain.

Battery replacement recommendation for Nexus One

I am looking for a Nexus One replacement battery. Any recommendation appreciated on where to buy something good and reliable (and what to stay away from).
A battery with a higher capacity but same form factor as the standard one would be great.
Thanks.

Mugen brand or Seidio

I'm gonna go out on a limb here and say the opposite of what most people will probably tell you... Go to eBay! I wouldn't eBay if you definitely need an extended battery, but if another battery with the same capacity of the original is good enough for you, you can get cheap knockoffs that perform as well as the stock battery without it costing you an arm and a leg.
My G1's previous owner must've overheated the original battery or something... it's puffed up and barely fits anymore and it doesn't hold more than an hour or two charge. I ordered a pack of three batteries off eBay that came with a wall charger. I got the batteries a couple weeks later. One battery was completely dead. One only holds about 90% as much as a stock battery usually does. One was perfect. I contacted the seller about the dead battery and he refunded my purchase price completely, no return required. All in all, it worked out pretty well for me... and the original cost was only seven or eight dollars.

new batteries

hi all, i need a few normal mah or one high mah battery i can trust so that i can use my note on my motorbike as a sat nav, please advise me on cheep yet ok batteries to use and where to buy in the uk
thankyou

I think maybe this will be a good choise for you, 5000 mah battery.
http://www.dealextreme.com/p/replac...g-galaxy-nexus-i9220-gt-n7000-116923?item=120
I have bought extra battery from DealExtreme a few times myself and my experience with them are good. That goes for the quality of the battery and the service. It took some time to get it delivered from China to Norway, But in your case, i think they have a UK storage facility.

I have this one: http://www.amazon.com/5000mAh-GT-I9220-SGH-i717-GT-I9200-Extended/dp/B002MPV0NW/
The battery itself works great. I am a very heavy user, and it is practically impossible for me to use the whole battery up in a day. However, I must warn that the battery door is very tricky. It doesn't quite fit right, and when you first get it, you really have to jam it on with a lot of force. After a while, I have broken several of the little tabs that fit into the back of the phone. It still stays on, but it isn't as tight as the stock door any longer. So, a mixed review on this one.

Need a replacement battery for your Nexus 7? I found one for ~$16 that doesn't suck (for now).

TL;DR at bottom. For those who like reading, continue..
I recently bought a Nexus 7 for tinkering and nostalgia reasons. I am really impressed that the tablet is STILL supported by custom ROM developers, pretty insane for a 8 year old device. However the battery life was terrible, reporting a capacity of ~56% via Accubattery. That is just poor and almost unusable in my opinion. Off I went on the Google machine searching for a genuine battery, most if not all were fake. I saw mostly photoshopped images of a generic batteries, that don't even look like the original. I did however find one listing of actual "new" genuine Asus/Panasonic batteries but they ship from China, ETA was over a month. Here is that listing for it: eBay link for ~$24. I am very impatient and decided to take a chance on this battery, shipping from California: eBay link The reason I chose this one was because I was about to purchase a battery from iFixit for $30, almost $40 including taxes and shipping. The battery in the second eBay link is the SAME battery shown on the iFixit page for less than half the cost. Insane. One of the reviews reported the battery only had around 83% capacity of 3950mAh with Accubattery, not good.
At ~$16 shipped, 83% capacity is helluva lot better than 56% and decided to go for it. The battery came well packaged along with those super flimsy small screwdriver set, adhesive stips and two plastic prying tools. Don't use the included drivers, they will strip the crap of whatever screw you try to remove. Opening the Nexus is the most tedious part of the battery replacement. I did crack the back casing where the headphone jack port is, it is not that noticable once back together. That area is the thinnest part of the casing and still cracked while being super conservative with prying. Once the back is off the rest of the battery replacement is much easier. Once everything was said and done I powered up the Nexus and the battery was charged to around 80%. And the improvement was already noticeable, the battery did not drain rapidly like the old one did. I drained the battery until it shut off, plugged in the charger and waited. And waited, and waited. It took over three hours for the Nexus to fully charge. And Accubattery reported... 90%! Granted this is just the first battery cycle but for $16 I could not be happier. I do not know if I got lucky with the battery I received but I cannot complain one bit. 90% capacity of 3950mAh! However the battery does suddenly cut off at 3%, something that the original did not do but that doesn't bother me. Draining Li-Ion batteries to 0% degrades them immensely, as well as charging them to 100%. Increase battery life (literally) by keeping the charge from 20-80%. This applies to all devices with Li-Ion batteries.
As for a long term test, we shall see. If the battery does fail prematurely I'll post an update here.
TL;DR: eBay sells the same battery for ~$16 delivered that iFixit sells for over twice the cost. The replacement battery has ~90% capacity of the advertised 3950mAh. Link for battery I bought, same as above: eBay link

Thank you for the link. Another battery power solution for our almost-a-decade-old device is no-battery mod and a cheap 10Ah (or more) power bank glued to the back. In this "configuration" Nexus 7'13 can survive independently of battery supply sources

Hello
I just got a nexus 7 2012 version from someone for free.
It does not turn on, does not charge. I tried all sorts of things including "jump starting " the battery.
Looks like I fried the battery doing that.
THe battery reads about 3.4 volts but it should be 4.7 volts correct?
Seeing all this, do you think its worth it to purchase another battery to see if this is the problem?
I am thinking its a dead battery with a reading like that, and wont accept charge anymore.
Any idea?
