First class service. I cannot recommend them highly enough.
About the product:
Excellent. I have had many laptops over the years and replacement batteries are an absolute minefield. Often they are neither genuine or are second hand, and often don't come anyway near the spec they purport to be. This was exactly the same spec as the initial battery supplied when I bought the laptop. Don't waste time and money, purchase from BatteryUpgrade.They are quality products straight from the factory, exactly what they say on the tin!
