Battery works perfectly, long life about 6 hours of constant use so not bad at all…

Worked great and glad I found a battery to work for my laptop last min rather then get ripped off from some computer shop !!!

The battery needs to be discharged fro 3% the first time andthen fully recharged. I just ran it installed. That said, thebattery does not slide in and out as the original battery does whichmeans it is slightly thicker. I had to use needle nose pliers and VERYgently pull on the plastic tag, ... I was fearful the tag would tear andthe battery would have to be dug out with a crib or something. It isthat tight.

I had called a nearby computer repair shop to inquire about a battery for my older laptop. They said that it was not available to them. I looked on Amazon and quickly found the exact battery i needed. I was skeptical at first as the battery was a fairly reasonable price. It has been installed every since I received it and performs very well. It lasts hours and hours, charges easily, and I couldn't be more pleased.

Lasted 9 months. Complete junk. Drops from 80% to 0% in 10 min.

So far has met my expectations for our use, did a recharge test and all good.. So to date, so far all is good.Good price for the product.And delivery date on time.

I've noticed my 3 year old original Panasonic battery would only hold a charge for about an hour and a half when it used to be almost 3 hours. This after market battery only keeps its charge for about an hour and a half to 2 hours. It works but not like an OEM battery.

battery is starting to charge less and less, 100 when new now it gets to the low 40s. I bought the battery 8 months back, contacted their customer service and they mailed me a replacement battery.
