Replacement 3.7V 1800mAh Battery for Samsung Galaxy S2 i9100

Pros: - Good Battery lasts 10 - 20% less than the original, but what do you expect for this money?
- Fits like the original

Cons: None so far

Other: Great battery, don't forget to order an external charger with it!

Pros: After 3 charge and usage cycles, I can report that the battery performs the same way as the original.
Charging time and discharge speed seem the same (I usually have to charge daily).

Cons: I wish I had an external charger - Having to use the phone itself to charge the battery seems risky (too often opening of the back cover).
One tiny con (really not important) - the plastic wrapping is very tight - had to use a knife to open it.

Other: If you consider a spare battery, and do not wish to go for a bulky opion, I definitely recommend this.

Pros: After 7 charge and usage cycles, I can report that the battery performs the same or even better. Nice to have a backup when heavy talking! When i last was in Singapore i also bought alot of spare camera batterys and often its the same factory who produc es them..

Cons: None that i can think of really. Its cheap and it works

Other: A good primary battery as its 1800Mah vs 1650Mah for the org. I definitely recommend this.

Pros: Was skeptical ordering two of these batteries but they work really well. I use it in my HTC a9100 phone (uses same battery as SII). Original battery was 1300mAh and thes batteries last a lot longer so probably is around 1800mAh. Seems well built.

Cons: none that I have fond so far.

Other: Great price for a good battery. You can't go wrong at this price.

Pros: The battery fits easily inside my Galaxy S II. It works just as advertised. Just plug it in, charge and you are good to go.

Cons: Doesn't work as long as the original battery, but it's pretty good as a backup battery.

Other: It's so cheap you can order 5 and it is fine. Just get a external charger to go with it and you are good to go. :) Very good value for its price!

Pros: - Last at least 3/4 than the original battery, its quite good considering the price. - Very cheap, i re ordered another one just to have another one :)

Cons: - I recharged it like twenty times so far and now it last 1/2 than the originall battery, but thats not really a cons, you get what you paid. - Switching it constantly may affect your phone's back cover, but here you can get a replacement for just a few dollards so its not really a problem.

Other: love dX :P

Pros: - quality not bad - cheaper option to get a backup battery for sgs2

Cons: - poor battery life (provided it was 1800mAh but still hold less than the original 1650mAh sgs2 battery) - the voltage drop below 3.6v even battery life was still 50%. (original battery could hold 3.6v+ above 30% battery life)

Other: Despite the price, it as still a worth purchase. Good for sgs2 user who need a backup battery.

Pros: Nice replacement battery for Samsung Galaxy S2 i9100 cellular phone, and works as promised. After charging it some times now, i can tell you that it`s same or even better than the original. Fits easily inside my Samsung Galaxy S2 cellular phone

Cons: No cons that i have found at the moment.

Other: And the bottomline is thats a cheap battery for Samsung Galaxy S2 i9100 cellular phone.

Pros: Battery very cool. Excellent for my fishing trips and for my bike. The material is of high quality. Had I known earlier, I would have bought another for my wife. But buy another soon! I love DX. The lens is glass and not tire of the views! Bateria muito legal. Excelente para minhas pescarias e para minhas viagens de moto. O material é de alta qualidade. Se eu soubesse antes, teria comprado mais um para minha esposa. Mas comprarei outro em breve! eu amo o DX. A lente é de vidro e não cansa as vistas!

Cons: I have nothing against. The product came in perfect condition. I have been using for over a month and so far is like new! Não tenho nada contra. O produto veio em perfeito estado. Já estou usando a mais de um mês e até agora está como se fosse novo!

Other: ok

Pros: Very Cheap for a backup battery, you can compare it with a 70% usage of an original battery. On the road to capture addtional pictures or to find your way out with maps its really helpful.

Cons: dont rely too much on it, you can extra juice on the road but not sure how long it might last..... as the battery gets beat up and used extremely the life may go down gradually....

Other: Very cheap, you can have an additional 5 of them in your backpack for a cheap price.
