Replacement 3.7V 1270mAh Lithium Battery with Clamp for BlackBerry 9800

Pros: The battery looks and feels like an original one and is of a good quality.
The code clamp works perfect and easy ( manual is included ) Just follow the instructions in the manual and its done in a minute.
If you want a good extra battery for a nice price, you have to buy this one.

Cons: I cant find any cons for this product. As it works perfect.

Other: A good priced top product from Dealextreme. Buy this Blackberry battery cause it saves a lot of money from the original. And the code clamp works very easy. Anyone can do it.

Pros: This battery looks and feels like the original, I haven't been done a side-by-side comparison of actual battery life, but this one seems to work well. The little clamp to copy the code takes a couple of seconds and is very simple to operate. It comes with instructions, which you primarily need just so you know how to positions the batteries and how to orient the copier. The led stays lit for a couple of seconds and then shuts off. You are then ready to use the battery.

Cons: Needs the code to be copied from a legit battery in order to operate.
If you completely drain this battery, it loses the copied code and you must re-copy it again. If you happen to be away from home, threw your old battery out, or lost your code copier; you may have a real problem getting your phone up and running again.

Other: It's very cheap so the limitations are not unreasonable.

Pros: excellent product i think that this is and usefull thing and and and and y really really wnjoy my blackberry with this batterry thanks you deal exxxtremmeee for give me the solution for my blackberry´s batterys problem, I´m really happyyy

Cons: shipping time , the ite iem takes a lot of time to arrive into my house, but it´s grate when the post man comes and give aou the to you, thanksss deal exttreme thankkss for that oportunity of buyyy i have an excellent experienceee

Other: nothing to say

Pros: -has same battery charge life as a standard F-S1 battery made by RIM

Cons: -Requires an original F-S1 battery made by RIM to function -Apparently if the battery ever fully drains then it loses that code duplication, requiring you to re-copy the code (never drained the battery fully so can't confirm that)

Other: For the price of this battery, it's much more practical to buy this battery and copy your original F-S1 battery then buy another OEM F-S1 battery at regular price.
