The Inside of This £500 Battery is Mostly a Sponge

“You get what you pay for” is one of those tried-and-true idioms that’s especially relevant in high-end electronics. Want a nice camera or a computer that’ll actually play Max Payne 3? Expect to shell out top dollar.

So imagine Markus Fuller’s surprise when he pulled open the chassis of a £500 replacement battery for the Nagra VI — an 8-track digital recorder that costs nearly £7,000 — only to realise its full of cheap components and a big, pink sponge.

Because there’s a higher-capacity version of this battery, Markus speculates that the sponge occupies the space that would be held by more cheap lithium-ion cells...for an additional £280. Something tells us that the “Do No Open” warning on the back is for more than just safety reasons: All told, Markus estimates the components are worth about £20.
