For those who don't have time to read the whole review I'll say two things right up front:
(1) You get what you pay for; and
(2) If it seems too good to be true, it probably is.

This battery works well for a while, but then it gradually starts to last for less and less time. Now, after a few weeks, it literally lasts less long than my normal battery does. So, overall, I would not recommend this battery.

This is not a knock on the seller, though. They supplied the product that they said they would and they offered good communication and support. It's just an inferior product.

I'm not upset because I didn't expect a whole lot for $17.50. So, just know that when you purchase it. You really can't complain when your item that costs three and a half times less than it's OEM counterpart.

I received these in a reasonable amount of time and found I had to contact customer service to see if what they sent me actually worked with my phone(they sent me a battery with 2700mah as opposed to the advertised 2800mah).The nice lady I emailed included a picture to confirm the battery I had and assured me it would work just fine. Upon looking at the photo she sent, I realised that it actually stated that it works with the i9000 series of phones, which the Vibrant I have is a member of, so if I just read the battery better, I would have seen that for myself, DOH!! Much thanks to their excellent customer service for a swift and courteous response! The battery works fine, dosent overheat or seem like its any different than the stock one, with the exception, of course, of lasting nearly twice as long between charges! You do have to remember to leave it on the charger for around 2-3 hours after the phone says its charged, though, then you will reap the extended battery life to its fullest. I highly recommend both the extended battery and the company to anyone, its a great bargain!

This worked decent for the first generation Galaxy S (Vibrant). Newer phones may not need an extended battery due to being able to last 15+ hours. But for the Vibrant, I was lucky to get 2 hours of use before needing to plug in. With this battery, I was able to extend the usable time of my phone to almost a whole workday. In standby mode, I could easily make it an entire day.
The case required by the extended battery was cumbersome. Additionally, I was no longer able to use my OtterBox while using this battery. Severely limits options for cases.

Got battery - it's labeled 3500mAH even though it is smaller than my current 3300. I installed it, charged it overnight to 100%, it was down to 20% that evening. Charged it fully the second night, same thing. After about 5 days of using it, unplugged it in the morning, it was down to 20% by afternoon, and below 10% before 6PM. This battery is definitely no 3500mAH battery (my 3300mAH would last 2 whole days when it was new) and I'd say this isn't any better than the stock OEM battery...maybe even worse. I am already shopping for another battery and will pay more attention to the negative reviews.

Cheap! I guess you get what you pay for. The battery fully charged will barely last on full day with moderate use. The cheap plastic battery cover is as thin as an egg shell and pieces cracked off on the first day. I don't believe this cover will make it two weeks before it's completely useless. I've had extended batteries and covers from other companies much higher quality than this! Don't waste your money buying this.

I did not feel like this battery lasted longer by any means compared to the battery that came with the phone. I have let it completely die and then fully charge, and still it runs down just the same as my other battery. I plan on changing back to the slimmer one today.

The only upside to this purchase was the speedy delivery. That's it.

I would not recommend this battery unless you do like the feel of a heavier backing.

Not a cheap knock off like most extended battery kits. The back is of high quality and not "egg shell" thin like most. The battery lasts twice as long as the original, and I use this phone for everything! I would absolutely recommend this product and the seller!

The extended battery life is excellent but the replacement cover for the larger battery is brittle and very flimsy. The first time it cracked, my two year old dropped it on the carpet. It has broken in several other places since and every time it does drop it basically explodes. The phone goes one way, the battery another and the cover another and I can't find a protective case that will fit the extended battery. The battery is, however, excellent.
