Worked great initially, but now will not take a charge after only 6 months! I have contacted customer service for a warranty replacement. I will update if successful.UPDATE: Futurebatt customer service is sending me a warranty replacement. No hassle, no fuss. Very fast response.UPDATE: Received replacement battery today! Extremely fast, responsive customer service. They stood behind their 1-year warranty! New battery is working and taking a charge.

While price and quality appeared good, the lack of capacity means only 3/4 the operating run time expected. Commented that product description should have said 32 Watts (Factory 40W)

Happy with battery was already charged when received.

This battery lasted almost one year before failing to hold a charge. It worked in my Dell Inspiron 15, 3000 series, however not as well as the original battery.

ALL IS AWESOME!! Don't be afraid to order! They take great care of their buyers!!!!!!!!

Great product, great price.

Item is as described. It fit perfectly for my older model laptop.

The original battery in my Dell laptop failed according to the laptop diagnostic and would no longer charge. I purchased this new battery and it immediately charged and worked.
