Review: Perfect replacement with longer wire - This was a perfect replacement batter for my old Dell E6430. It has a longer wire which worked out just fine. So far so good. I measured battery voltage before install and it was approx 3.3V. I'm glad that these are still available for old laptops!
Review: Easy to install. - So far so good. After one month I couldn't complain. From first day works really good.
