Review: This is the battery I needed when mine died. What else can I say? That said, I wanted to make a point, because it's not been the first time excessive packaging was used when a small bubble-wrap envelope would have been the RIGHT choice. In this picture you see a small battery on a static bag on a paper envelope. Which was in this over-sized box. Imagine my surprise when I received notification that the package wasn't delivered because it wouldn't fit in my mailbox. It's a small battery. Really folks? Can't we perhaps fix that broken packaging algorithm? Maybe enough attention to this problem and they'll fix it. Please people, pay attention and give a care.

I ordered CMOS battery, and I have given the Model # also, the battery socket that goes on the motherboard is not right size. I did sort try to take out the battery from the side that is wires soldered to the battery. I am not going to return the battery, please see the attached pics to see the difference. I have attached the pics the two wires the one with smaller socket is the original sony battery with the model number ML 1220-M3(HLF)-F 0424.12 for Sony Vaio laptop model SVS151A11L.
