How the replacement works
- Unscrew the case bottom screws and lift the plate assembly gently; use the driver Keychron supplies for your revision.
- The battery sits in the case bottom with a two-wire JST-style connector. Unplug, swap, replug.
- Avoid prying near the battery itself; puncturing lithium cells is dangerous.
Where to get the part
Contact Keychron support with your order number and ask for the Q1 Pro battery part; they routinely sell spares. Generic batteries with matching voltage, capacity and connector exist, but verify polarity on the connector before plugging one in, since it is not standardized between brands.
Is it worth doing?
If your battery still charges but runtime has dropped, a swap restores wireless life for a fraction of a new board. If the board is under warranty, ask support first; a failing battery within the warranty window is their problem, not yours.
Habits that slow battery aging
- Lithium cells age fastest when held at full charge and high temperature. If the board lives plugged in at your desk, unplug it now and then and let it run down partway.
- The widely used guideline for lithium packs is to spend most of their time between roughly 20 and 80 percent charge; the board does not enforce this, but you can.
- Turn the backlight down or off in wireless mode; it is the dominant drain.
- Storing the board unused for months? Leave it around half charge, not full and not empty, and somewhere cool.
Worn battery or something else: a quick diagnosis
Before ordering a new cell, rule out cheaper explanations.
- Short runtime but otherwise normal: classic battery wear, especially after a couple of years of daily wireless use.
- Will not charge at all: try another cable and port first; USB issues masquerade as dead batteries constantly.
- Dies suddenly at a healthy-looking percentage: a worn cell whose reported charge no longer matches reality; a swap fixes this too.
- Wireless drops but wired works fine: that is a radio or interference problem, not the battery.
If the board is under warranty, stop here and email Keychron support with the symptom instead.
Handling and disposing of the old cell
Treat the removed battery with respect. Put tape over the connector so the terminals cannot short against metal in a drawer, and never puncture or bend the pouch. Do not bin it with household waste; battery recycling points at electronics stores and municipal collection accept lithium packs. One more caution: if the old battery looks swollen or the case had become hard to close, stop using the keyboard on battery power immediately and remove the cell carefully without pressing on it. A swollen lithium pouch is the one situation where this stops being a casual weekend swap and becomes a handle-with-care job.
