  • Good replacement battery

    posted by Lazor2

    I have used and tested this battery for a while now and I can say that it's a good replacement. I bought a new one just to have a spare battery and to see if I could squeeze out some more battery life from my G1. And it the end I actually did, this battery lasts a bit longer than my now overused old battery. (Batteries life decades after a while)
    I have noticed no strange hot temperatures while charging, works regular like the original battery.
    If your thinking of buying a spare battery for your G1, this is a great replacement for a great price! Original branded batteries cost a lot more!
  • Works well, but makes the phone very bulky

    The battery has a very long life compared to the original battery. I can use my Bold for 3 days in a row, instead of one and a half day. The cover also fits very well, is quite decently made and looks nice in this matte black colour.
    Compared to an iPhone, this battery is way too thick for its capacity. The original BlackBerry battery is rated at 1500 mAh, this one at 3000 mAh and an iPhone's battery at 4510 mAh (http://www.ifixit.com/Teardown/iPhone-3G-S/817/2, look for the picture).
    This battery works well, but you have to live with its design flaws. Hopefully it will last long. The price is unbeatable.

    Good battery capacity
    Compliance with the size of
    Good build quality
    There is a fee protection
    good packing
    High-quality assembly
    Good battery, but the price could be lower. Capacity is almost the same face value. Built-in protection - it's good for the battery. Ideal for large lamps. Can give a high current. The box for the batteries - excellent. You can carry in your pocket with keys.
    I recommend to buy. Good product. Money well spent.
  • Great Battery, Holds a Decent Charge

    Very good battery, Works great , Holds a long charge, dont have to charge for atleast 1.5 days, i can use BBM, Facebook, MSN, and wifi all day and its no problem, holds the charge well
    GREAT PRODUCT,,the same battery will cost you $25-$40USD anywhere else. When you receive the battery, dont charge it, let it drain all the way first then charge it all the way
    For the Price you cant complain, decent product does what it should, and lasts long.
  • good cells

    posted by erwinh

    good price and good quality for the money
    discharge protection - so the cells will be not getting bad if they are discharged low
    I have tested the capacity from the 14500 cells!
    First i charged one cell the whole night with almost 4,2V by regulated power supply. In the morning the charging current was at a very low level.
    Next i discharged the cell with 100mA constant current and i noticed the voltage every 30 minutes (at the end of discharging permanently). After 7 hours (700mAh) the voltage (3,3V yet) fell faster, until the voltage reached 2,5V and the protection of the cell turns off the test circuit (0V). The discharged capacity was 770mAh.
    After disconnecting the cabels, i measured 2,8V at the cell (slowly growing). Then i chareged the cell again for using in my ultrafire c3 flashlight.
    I haven´t tested overcharge protection, because over voltage is very bad for Li-ion cells.
    Good capacity (770mAh) for this price.
    When the lifetime is long (i will see), i can fully recommend this rechargeable Li-ion battery.
