I turned to BatteryUpgrade.com out of desperation; my 74-year old father had been spending days in the killer Delhi summer (45-deg C) heat trying to find a replacement battery for his Acer Aspire laptop. None of the dealers had it and Acer India's response to my email was truly apathetic (read: non-existent). BatteryUpgrade proved to be a lifesaver; the ordering process was simplicity itself, the interface was idiot-proof, delivery was spot-on and I actually paid about 40% less than the price the local dealers were quoting (for a non-existent product)
About the product:
I ordered a replacement battery for my dad's Acer Aspire 5500 laptop. I got a battery that had even more juice than the one it replaced. If I remember correctly, the battery was delivered on the 7th or 8th day, well within the stipulated 14. The battery was nicely wrapped and padded for the journey, and has been working great ever since. Thanks, people!
