The new listing from the Federal Communications Commission or FCC appears to shed light on what fans should expect from the upcoming Nintendo Switch console. Based on the document that is now up on the FCC website, the gaming device could launch without a removable battery.

According to My Nintendo News, the Nintendo Switch is currently listed as a console with a non-removable battery. This basically means that the Japanese video games company is departing from its previous console-manufacturing ways. It can be noted that it launched the Wii U GamePad with a replaceable and upgradeable battery.

Because the Nintendo Switch is intended to be a hybrid console for home and handheld gaming, it requires a battery to power it up for on-the-go gaming. Dual Shockers says having an upgradeable battery is proven to be beneficial with the Wii U GamePad. For example, the 2012 console got a boost of 266 percent of battery life when its battery is upgraded.

Since there are no specific details about the non-removable battery of the Nintendo Switch at this point, there is no way of telling if the console can last a good amount of time before it needs to be refueled. More details about Nintendo’s next big venture are expected to be revealed this Jan. 13, 2017 during the Tokyo Webcast.

Meanwhile, a Famistu ad for the Nintendo Switch has already confirmed that there is going to be a hands-on event for the gaming console at Tokyo Big Sight. The event is scheduled to happen on Jan. 14 and 15 from 10 a.m. through 5 p.m. JST each day. Visitors and fans are welcome to check out the Nintendo Switch during these times, but Nintendo Everything has learned that only those who arrived before 4 p.m. JST will be accepted to go to the booths and experience what it’s like to play with the console.

The Nintendo Switch is slated for release in March 2017.
