Safety first—we dispatch the battery connector before prying this sucker off its adhesive.

Most consoles have a power supply, rather than a battery, but the Switch's portability demands wireless power. And that usually means a limited lifespan.

Unlike the 3DS, the Switch battery isn't meant to be user-replaceable. Instead Nintendo "plans to" offer a paid replacement program.

The Switch packs a 16 Wh battery—bigger than the 5.6 Wh replaceable battery in the Wii U GamePad. Then again, this is powering a console, not just a display.
