The battery for my laptop is just like new product reasonably priced and delivered on time and even a day early this a great place to shop I'm very satisfied with this company ~Gary Dusenbery
The battery I needed and ordered was the battery I received. Delivery was fast, charges were accurate and company follow-up to my purchase was A+. The battery itself charged quickly and completely and yields approximately the same use between charges as the original that came with the notebook. The price beat the competition handily, too. ~H R Chafin
So far so good, I received my product last week and it works well. I received my item by mail quickly. I am excited about the website because the are very accurate in making sure you pick the accurate item. This item was hard to find in store and the company was able to take care of my needs asap!!! Great... ~Annetha Bagsby
The item was exactly as described on the web site, and customer service responded promptly to my question. Great company, would definitely order from them again. Thank you! ~Lisa
I wasn't sure how I would like this battery because it inclines when attached to the back of my laptop. By my surprise it I love it. It helps with my posture. It's a very functional design. ~Toni Battle
I received the battery in what looked to be good condition. After I installed the battery I found it did not want to snap into the battery bay. I looked it over and found what looked like it had been dropped on one of the outside corners. This was keeping it from snapping in. I then looked over the bubble packaging for possible damage spots and found USPS did damage the battery. So I sent an email with photos to Nextdaypower. They responded with an email that replacement was on its way and directions how to return the other battery and a free shipping return label...NO Questions or run around. I have received the replacement and it snapped right in and started charging with no problems. Just want to say I am totally satisfied at this point. I would recommend Nextdaypower to anyone. Nextdaypower had the best price on the internet and I am glad I gave them my business and will in the future. ~Daniel Conrad
