Satechi’s new Slim EX keyboards have a replaceable battery

Satechi is launching a new pair of wireless keyboards with a rechargeable battery designed for easy replacement. Despite their ultrathin profiles, the compact Slim EX1 and full-size Slim EX3 both stow the removable battery in a compartment on their undersides.

A wireless keyboard with an easily replaceable and rechargeable battery is hard to come by, especially one as thin as the Slim EX1 and Slim EX3. Satechi says you can access the lithium battery by removing the Phillips head screw on the battery compartment on the back of the device and then sliding off the access door. Lithium batteries don’t last forever, and this design change should make the keyboard’s battery pack simple to swap out when it degrades down the road.

In addition to this improvement, both devices automatically remap keys for use on Mac or Windows and can also connect to up to four devices, including those running on Android or iPadOS.

The two keyboards come with quiet scissor-switch keys, charge via USB-C, and offer up to five weeks of battery life. Satechi’s Slim EX3 Wireless Keyboard, which comes with a numeric keypad and navigation keys, costs $69.99, while the smaller Slim EX1 costs $49.99. Satechi is also launching a Slim EX Wireless Mouse with a replaceable battery for $29.99. Satechi says the battery on these devices will be covered under warranty, adding that customers can contact the company for a replacement.

The Slim EX keyboards and mouse come in black or silver. They’re available for purchase today on Satechi’s website and via Amazon.
