      Customer Reviews
      My battery shipped FAST and was a perfect fit for my M1530. Very pleased with the price. My laptop now runs on battery like it did when it was new. DEFINITELY RECOMMEND!

      Customer Nolan

      I lost my laptop adapter and found the replacement here. The site was easy to use, and my order arrived in 3 days. I have to thank you for getting my laptop up and running again :)

      Customer Nathaniel

      We are a high school. Searched a number of sites for the battery for our laptops and found this site. Not only was the product a great price (better than anyone else), their batteries outperformed the OEM. Thank You for a great experience!
