EC TECHNOLOGY 2300mAh Li-ion Battery - T-Mobile Samsung Galaxy S II SGH-T989

http://www.amazon.com/EC-TECHNOLOGY...1347070326&sr=8-2&keywords=anker+battery+t989
I was searching for Anker battery on Amazon and saw this first. I never seen this battery until today and no ones posted a review on Amazon. Its only a bit stronger than Anker but I was thinking about purchasing these just to see how it goes. I've used the Anker batteries before so I'd feel more comfortable buying Anker other than EC, but still wondering if anyone bought these before. Comments?

I bought some EC 1800 batteries and the universal charger and they are OK they last a little longer than my stock battery. They say they don't work with NFC on the nexus but not sure about gs2 because I never use it.
All in all decent product comes in a nice packages, which was nice to not get bulk packaging from amazon.

Quick battery question

So best buy sells a 1750mah battery for $50. Is it worth the price and would it be that big of an upgrade over stock?

At $50 you might as well get the seidio 3500 from amazon. I also advise you to use an external wall charger if you plan on using any other battery besides the htc stock.
There are cheap batteries all over eBay. I bought two 1500mah batteries with a wall charger for $10 and two 3000mah batts with two battery covers for $20.

Where?
I wouldn't want to buy for an untrusted seller by accident.
Thanks
They are literally ALL OVER ebay, and they are pretty much all the same. Just look at the seller rating and feedback. If they have a high rating and mostly positive feedback, youre safe. Plus, it's not that big of a risk, you're only talking $10-20.
These are the 1500 mah batts + charger I ordered
And these are the 3000 mah batts

[Q] Anyone have experience with this universal charger?

I came across this charger and the price looked good, particularly considering that it's supposed to work for a variety of batteries. I wanted to get a spare battery for my Vibrant and a wall charger, but the standard Samsung OEM battery charger seemed too pricey.

This comes with a battery and its onlh 50. Thats a deal if you think about paying 50 for just the battery thro t mobile.

Thanks, I did know about that, and it's still in the running. However, at Amazon, you can get a Samsung OEM battery delivered for about $18, so I was thinking: battery $18, + universal charger $13, total $31. If the battery is really what it's advertised as, and the more versatile charger is decent quality, that would be my choice. Hence, my question about whether anyone had experience with this particular universal charger.
Im not a big fan of none name brand parts. Thats just me tho im a little paranoid.

I generally am cautious about that, too. However, it's a struggle between buying something of unknown manufacture that may be reasonably priced and decent quality, or paying for an over-priced, name brand accessory. That's why I was hoping someone who bought this charger could comment on its quality.

Which battery should I get?

I can either get a replacement battery, 2 of them + a charger for $25. http://www.ebay.ca/itm/Anker-1900mA...ccessories&hash=item4ab3e5b7e8#ht_2690wt_1252
Or an external very portable battery 2600mAh for $25
http://www.ebay.ca/itm/Anker-Colorf...t=LH_DefaultDomain_0&var=&hash=item7916fc4474
Or external battery (not as portable) 3600mAh for $25.
http://www.ebay.ca/itm/Anker-Extern...ccessories&hash=item4cfeea48ef#ht_6381wt_1361
All the same price. I'm thinking of getting the colorful anker battery. I could charge the phone while both are in my pocket. Since it's more than one charge, I don't have to worry since I can easily charge the battery again.
Or I can get a single Anker battery for $18.

What do you guys think?
I recommend the 2 Anker batteries with charger because that's what I have and the batteries last the same or longer than stock. Also I always have a extra battery In my pocket and a extra at home.

I can't use the charger as an external battery, can I? Like plug my phone into the charger via USB with the battery in the charger, and charge without AC connection?
@OP, any specific reason to not include the Samsung 2000mah battery+cover in that list? Because that is certainly what I would recommend.

I agree 100%. It's the battery they should have included as standard, but i'd reckon the marketing department wanted the lesser capacity battery so they could say how thin the phone is.
Any way, i got a couple of generic batteries off ebay, and my god they were awful to use. Maybe it was my experience, but the phone would get so warm using them and they would drain in less time than the genuine battery even though they were the same capacity.
Maybe it's just my experience, but i'd go genuine from now on based on what happened to me.
Hearing a lot of positive feedback for the anker battery... Might try it myself...
get the anker or that first link,i brought me another samsung battery and a wall charger and its great,use a battery a day and charge the flat one when you swap them over,its worth it,glad i did it.

i am new here, just find anker astro3 10000mah external battery it looks amazing and only $49.99
could anyone give some reviews?
much thanks
I use the Samsung 2000 mah battery and I also have a 1900 mah Anker as a spare in my pocket.
I just carry a small piece of cardboard with the Anker battery so it can sit tightly in the extended 2000 mah case
Both batteries are fine but I prefer the Samsung one.
I have two anker batteries that I rotate with stock battery. I really like having an external charger and being able to charge batteries indepenantly. Very impressed with the anker brand and the affordable price. Just my 2c

WOW,10000mAh huge capacity
Anker
Recommend anker, 1 year of user.
The Amazon reviews of the Astro3 external USB backup battery are impressive. Reports of people charging a phone and an iPad2 (a greedy device if ever there was one), charging two devices while watching video on one, etc. Very tempting for the price, it sounds like just the thing for a cross-country plane flight.
Really interested in personal reports here....
i am rocking this anker. charges almost all my devices, not just my phone. if anyone buys it of amazon please pm me so i can send anker referrals

This.
If that is not an option, I would go for the two Anker plus charger
I'm tempted to finally pickup the Anker 10000. Can anyone tell me if it can be CHARGED via USB? or can it only be charged from a wall?

Recommended Power Bank with >4000mAh battery ?

Hi guys,
I'm looking for a not too expansive power bank with >4000mAh battery for travels (USB [email protected] output).
Any recommendations ?
Thanks
Try looking up for Yoobao battery banks. I've had a couple of these, a 6000mAh one cost me about 40$ or so the last time I bought it which is last year.
AFAIK prices fluctuate pretty badly based on which seller it comes from, so look out for cheaper deals.
I think they're pretty good and they are way cheaper than the more "established" brands.
I have an anker astro 3 10000 mah power bank for myself. It works great! Two USB outputs, each one supplying 2 amps. I think anker is the best deal. Its like 60 bucks. And has good ratings on amazon. Alot of the other power banks don't work as advertised but this anker one does well.
Now I don't think it has exactly 10000 mah, but it is probably about 8000. I could probably do a test to see how many charges I can get with the sgs3.
http://www.amazon.com/10000mAh-Exte...F8&qid=1341939937&sr=1-1&keywords=anker+10000
I'll also see if I can take some pics of its size. Its not too big. But that's just my opinion so I'll see what I can do

I have good experience with Anker products but I can't buy from Amazon and can't find it anywhere else. I'm still looking.. I guess that if i'll not find another store (with international shipping) I'll go for the Yoobao...
Thank
PS
AliExpress having a 50% off sale from the 16th till the 21st.
Do you think it safe to buy the Yoobao from there ?
Is the Yoobao batteries trustworthy? Do they actually have the mAH posted?

External Battery Pack for my Android device?

I'm currently looking for suggestions and feedback on and external battery power extender specifically for my Nexus 4, and maybe for an iPad occasionally.
I've been skimming online all day, looking at different brands and models. One battery that seems to fit my needs is from a company named New Trent:
http://www.amazon.com/New-Trent-NT7...qid=1367450278&sr=8-1&keywords=newtrent+nt70t
Anyone have any previous experience with this company and their products?
I'm mainly planning to use this to keep my phone charged when I'm not near any wall plugs or when I'm on vacation.
How much extra charge should I expect from this battery pack?
Any insights on this would be much appreciated.
I don't know about their batteries but they do make some killer micro fiber styluses.
You'd probably get 2 good charges out of that back up pack, assuming their #s are solid.
I haven't tried that specific brand, but I have used a few others. I currently use the Motorola P893 (89536N) which is only an 1860mAh battery pack and I get about an 80-85% charge on my Galaxy S II 1850mAh battery. So if it's anything like this one, expect about 80% of the rated capacity to be actually usable. Thus 7000mAh would translate into about 5600mAh of useable juice. The Nexus 4 has a 2100mAh battery, so I would guess you would get a solid 2 charges and still have some juice left over.
Hope that helps.
Monoprice.com has a nice external pack for a great price. I have one and like it.
I can't post links yet, but its under $29 for a 5000Mah pack.

Interesting, going check this site out
New Trent
I am a beta tester for New Trent and they have wonderful products. I currently have the PowerPak + NT135T. It has 13500 mAh which is huge considering most phones have close to 2000 mAh. I can charge my Nexus 7 (2013) and HTC One at the same time without a hiccup. It's only $54 and can recharge a Nexus 4 5 times.
If you go on amazon and search for external batteries, the #1 brand with thousands of 5-star comments is Anker. I have reviewed every brand of external batteries, and wrote a ton of detailed reviews in the sticky of this Accessory section of XDA (and in my sig link). I have looked at Anker, New Trent, RAVPower, Yoobao, etc... A lot of good trusted brands, but customer support, warranty (18-months), variety, and recent 2nd gen introduction to stay ahead of other cookie-cutter CH generic brands really sets them apart.
