Satechi Slim EX Keyboards Offer a Rare Replaceable Battery

Satechi is making waves at CES 2026 with its new Slim EX keyboard line. Bucking the trend of disposable tech, these wireless keyboards feature a user-replaceable, rechargeable battery. Finally, a keyboard that isn't destined for the landfill the moment its battery gives out.

Design and Features

The Slim EX line comes in two models: the compact Slim EX1 and the full-size Slim EX3, which includes a number pad and navigation keys. Both maintain an impressively thin profile, considering the inclusion of a battery compartment. Satechi cleverly hides the removable lithium battery under a small door secured by a Phillips head screw. According to The Verge, accessing the battery is as simple as "removing the Phillips head screw on the battery compartment on the back of the device and then sliding off the access door."

This design is a welcome departure from the sealed, glued-together construction common in many modern peripherals. I'm tired of seeing perfectly good keyboards rendered useless simply because the integrated battery has degraded. This move from Satechi is a win for consumers and a small victory for sustainability. It's a feature that addresses a real pain point for anyone who's experienced the frustration of a keyboard with diminishing battery life.

The Value Proposition

The real value here isn't just the replaceable battery itself, but the extended lifespan it offers. Lithium batteries inevitably degrade over time, leading to shorter runtimes and eventually, a useless device. By allowing users to swap out the battery, Satechi is significantly extending the usable life of these keyboards. This translates to long-term savings and reduces e-waste. The price point will be a deciding factor, of course, but if Satechi can deliver this feature at a competitive price, it could be a major selling point.

It remains to be seen how readily available replacement batteries will be and what they will cost. If Satechi gouges consumers on replacement batteries, the value proposition diminishes significantly. However, if they offer reasonably priced replacements, the Slim EX keyboards could become a go-to choice for users who value longevity and sustainability. This is a smart move by Satechi, and I hope other manufacturers take notice and follow suit. The future of tech should be repairable and sustainable, and Satechi is taking a step in the right direction.
