  • great battery for the price

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    the batteries came half charged.
    their size is 14,2mm x 51,85mm(they are a little bit longer cause of the protection)
    the protection works very well, it cuts off at~2,65 Volts
    and the short circuit protection works great, too.

    Cons:

    when you want them to charge full, you shut charge with
    about 100ma, cause if you charge them quicker the overload protection cuts to early, thus they are only charged maybe to 85%.

    OtherThoughts:

    the capacity is about 790mAh by discharging with 1A till the protection cuts off. When you discharge them very slow, 900mAh are almost realistic
    the internal resistance is about 220mO each cell.

    Bottomline:

    fantastic batteries for the price, protection works well and the capacity is ok.
