Customer Reviews from Amazon
“My Sony SZ laptop worked well for the first 13 months of ownership and then the laptop battery died. Not just poor battery life but outright died – most likely due to an internal short in the battery pack. Checking my warranty information I found that the battery is not covered by the extended warranty I bought, was beyond the one year Sony warranty and not subject to one of Sony’s battery recalls. After some serious Googling I learned that the replacement batteries are expensive, generic batteries are about half the cost and some folks have reported bad experiences with generics. When I looked into the generics I did note that the power density was not the same as the Sony branded product – look at the mAh rating and the higher the better. Further Googling evidenced that website was price competitive and I had the assurance of the service. The new sony vgp-bp2c battery arrived quickly and is an exact copy of the original I had in my Sony laptop when I bought it. My only wish is that they were cheaper and longer lasting.”

“Purchased the sony vgp-bps2c battery for my Sony Vaio VGN-SZ160P about 3 months ago (March 22, 2008) and it works just as well as when the computer was originally purchased 2 years ago. It’s unfortunate that the battery needs to be replaced within 2 years, especially at such a high price point ($171.99). I guess that comes with the territory.

UPDATE (Feb 20, 2009): Now just under a year of using this replacement laptop battery it has already died like the original that came with the now three year old VAIO. The price has dropped to $160 but I’m unsure if I’m willing to keep paying so much every year for a battery. Since I travel I may be forced to make another purchase.”
