Customer reviews
As described. Perfect.
I have been using the new battery for a while now and I'm very impressed!! I have tested the new battery to the max and without a doubt, it holds its charge! From my experience so far, its as good as an original, if not better.
Perfect replacement battery for my laptop
Initial battery was incompatible with my Dell laptop but replacement works very well.
Working very well.
When my laptop battery failed I looked straight at the Duracell web site & ordered the ideal replacement, brilliant.
Ideal replacement and cheaper than manufacturers own item
Laptop now has 4 hours' battery time (before installation of new battery only 1.5).
I bought this as a replacement battery for the 4 cell 40Whr N121Y battery in a Dell Inspiron 3521-15 laptop computer. It fits and works O.K.
The battery seems fine - it works (!) but I've only had it a week. Difficult to review a battery in the early days or at all really without testing equipment. It works!
