30 hours of continuous gaming on a full charge. Third party replacement batteries are also available. The battery was originally not thought to be replaceable when a Sony spokesperson stated that the Sixaxis should operate for "many years before there's any degradation in terms of battery performance. When and if this happens, then of course Sony will be providing a service to exchange these items". Later, it was revealed that the Sixaxis came with instructions on how to remove the battery and that the battery was fully removable. The DualShock 3 also uses this battery. The Sixaxis can also draw power over a USB cable via a USB mini-B connector on the top of the controller. This allows the controller to be used when the battery is low and is also used for charging the battery. When connected via USB, the controller will communicate with the console over the USB connection, rather than wirelessly. This also applies to the DualShock 3. LEDs On the top of the controller is a row of four numbered LEDs, which are used to identify and distinguish multiple wireless controllers. These are similar to the indicators found on the Wii remote and the ring of light Xbox 360 Controller. Since the PlayStation 3 supports up to 7 controllers, but the controller only features 4 LEDs, controllers 5, 6 and 7 are represented as the sum of two other indicators (for example controller 5 is represented by illuminating indicators '4' and '1' at the same time, since 4+1=5). Sony also patented a technology to be able to track the motion of these LEDs with the PlayStation Eye camera for use alongside the PlayStation Move Controller. Though this was never utilised with the DualShock 3, its successor, the DualShock 4, features a light bar used for motion tracking, as well as player identification.
