• Carefully check the part number.
• Always compare the specifications.

• Battery Cells Manufacturer: Is the cell manufacturer listed on the competitor's site? If not, this is when a question should be raised. If a website does not list the battery cell manufacturer, the battery most likely has China-made or inferior battery cells which are not the best of quality cells, and the battery life is typically half of what you'll find with our batteries. Some of these cells have been recently reported to catch fire, which is not only dangerous but quite costly if you have to purchase a new laptop.
• Capacity: Make sure the battery you are comparing has the same capacity, check that the mAh and wHr are the same. The higher the capacity, the longer the battery lasts on a single charge so the prices are higher for different capacities.
• Battery Grade: Does the website publish what type of battery Grade they sell? Lower grade battery cells B & C do not last as long. We only use only Grade A battery cells which have the longest life span.

• Make sure the connections are perfect

Our schools really appreciate Laptop Battery One’s product and have found that it definitely saves them a lot of money. They have so many good things to say about the product that it is almost overwhelming.

“Thank you for the excellent service, your company deserves a five star rating. I was impressed with your representative when I placed my order but it didn't end there. She knew her products, was friendly, easy to understand and made sure that the products were right for my computer. The order was placed on Monday to your company in California and was delivered without any delays two days later in Florida. I was provided with a tracking number during this time but hardly had time to use it. We have now installed the new batteries, following your instructions, and delighted with the performance and high quality of your products.”
