Keyboard Logitech K800 Battery replacement

Difficulty

Very easy

Steps

1

Time Required

5 minutes

Introduction

If your keyboard blinks red and refuses to work (this may happen by alternate before becoming definitive) it's probably because you need to change the batteries. I received a keyboard with broken batteries so it can actually happen DAY 1.

Another issue may be a broken cable inside at the battery level.

    • Once the battery location open, replace the original battery with new rechargeable batteries.

Conclusion

To re-assemble your keyboard, reverse instructions.

If the keyboard doesn’t work with the new batteries, doesn’t charge the batteries, or doesn’t communicate with the unifying receiver, a mainboard replacement may be necessary. The replacement circuit board can be purchased via eBay. Search eBay for “210-000797” which is the code for the PCB.

Actually, if the battery change doesn’t work, it’s more probable that the issue is a cable disconnected around the location of the batteries. A little piece of tape on the cable will fix it!

They changed the design. The batteries are no longer accessible through the slot. They want you to trash it and get another one. Can you guys do another teardown for the new eco-destructive design?

yeah I have design purchased from bestbuy around 2015 or 16 with hidden battery and 50 steps to replace.

This tutorial on how to replace the old k800 version batteries easily accessible under the simple cover plate is sofa king useless :)

ok maybe people actually need tutorials on how to replace batteries in remotes or flashlights, my bad.

If you’re looking for a solution in the exact same model, you can still remove the entire backside of the keyboard and replace batteries :) . It’s a bit more complicated, but I did it and it’s fine. You can find videos online about how to do it.

I also have the design with the hidden battery :( I would benefit for an update of this tutorial

Edit:

I found the new version here Logitech K800 Battery Replacement

Hi, first i had to change the battery and replaced it. After that the in/off switch was broken. Now i need a new pcb batteryboard rev.005. with 3 pins connector. I found rev.007 with 4-pins connector. Is it possible to built in the 3pins battery on a 4pins accuboard rev.005?? Maybe someone can help me out. 🥴🥴🙏Greetings Jorne

in my K800, the rechargeable batteries are AA, not the triple-A size noted in the Parts Needed section above.
