When we’re testing our refurbished laptops the battery is a key part. What we want to ensure is that any customer who receives a laptop isn’t going to have an overly worn battery. We don’t replace all batteries as it would be damaging to the environment doing it unnecessarily. We apply condition boundaries to our batteries of 80% design capacity or 750 cycles. We found this to be the correct balance between the impact on the environment and the customer experience.
