Added 23 April 2022: Don't believe Sitejabber's overview. There's no way 10 1-star reviews and 4 5-star reviews means most customers are satisfied. And by simple arithmetic that is a 2.14 star average.
LaptopChargerFactory advertises availability of most laptop batteries at discount prices, and say they can upgrade to genuine O. E. M. Batteries for an extra fee. They also claim quick shipping to all U.S. states.
What they delivered, in my case, was two months of runaround, multiple requests for more money, not one promise kept, no product ever shipped.
When they finally decided to quit trying, they promptly refunded all my payments through PayPal, so I'm not out any money, just two months of exasperation.
I would not recommend sending any payment to these people except through PayPal or by credit card so that you have recourse if they don't perform.
