5.0 out of 5 stars Perfect item - if you don't care about packaging
This is the genuine article - an original Sony Vaio BPL12, brand new. Got the item few days ahead of delivery estimate, Speedy Mobile is indeed speedy! The battery works great, full capacity and is brand new. However there is no retail packaging. The battery is well packed in a generic white box. I was initially worried that I got a non-Sony battery, but when I tested it,...

2.0 out of 5 stars Doesn't live up to expectation
Bought this to get more time unplugged. Has not happened. I am lucky to get 4 hours. After 1 hour unplugged my CD/DVD player shuts down to conserve energy....disappointed so far

The battery works great, full capacity and is brand new. However there is no retail packaging. The battery is well packed in a generic white box. I was initially worried that I got a non-Sony battery, but when I tested it, it works great. Now my Vaio Z36 lasts about 10 hours on light use! It frees you from having to bring the AC adapter and makes my backpack much lighter!

5.0 out of 5 stars Significant improvement over regular battery, August 26, 2011

This review is from: Sony VAIO VGP-BPL12 Extended Battery for VGN-Z5 Series (Silver) (Personal Computers)
Be careful buying these replacement batteries. They have circuitry that talks with the laptop to report how much time left, percentage charged, etc. So if you buy an off brand, you may be required to flash the BIOS on your laptop to make it work with the battery. Then what if you want to use the old battery as a spare? This one is a Sony product and works perfectly out of the box. Don't take that for granted. One Amazon Market Place Vendor attached his third party battery to this Sony description. I call that fraud. Luckily I noticed the Vendor Description said they provided third party replacements. I wrote them an email before it shipped. They said, "Don't worry, we provide the flash software. It's as good as an OEM." I canceled the order before it shipped. Also reported it to Amazon. Anyway, this Sony brand is sweet. My old battery was not lasting the whole day. This new extended battery has let me forget about the battery again. Nice. It fits a little tighter in my laptop sleeve and tilts the keyboard a little - like raising the back of a desktop keyboard. It's probably heavier too, but I don't really notice it.
