About this replacement
Linak Deskline CBD6S / Homeline — 24V Li-ion Replacement Battery (BA001)
This is a 24V, 2100mAh Li-ion replacement for the Linak BA001 battery. It fits the Deskline, CBD6S, and Homeline controller units. These controllers manage height adjustment, motor drive, and preset memory on Linak-powered standing desks.
- Deskline / CBD6S / Homeline compatibility: All three platforms share the same 24V controller architecture and use the BA001 cell pack. The BMS handshake, connector pinout, and voltage rail are identical across these lines — one battery covers the full group.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a CBD6S controller. The BMS accepted charge without fault flags, voltage held steady at 24V under motor-start draw, and the controller completed height adjustments across the full travel range without interruption.
- Preset memory after swap: The Deskline controller stores height presets in a memory module backed by this battery. Removing the old battery — even briefly — clears all saved positions. After fitting the new battery, re-program every height preset from scratch before returning the desk to use.
Why the CBD6S loses height memory when the battery dies
The Deskline controller does not use non-volatile flash for height presets. It relies on the BA001 battery to hold a continuous trickle voltage to the memory module. Once that voltage drops below roughly 20V, the controller treats it as a cold start and wipes all stored positions. A battery that reads low but hasn't fully failed yet will cause intermittent preset loss — heights disappear and reappear depending on charge state. Replacing the battery resolves this; recalibrating presets afterward is mandatory.
Controller not responding to up/down inputs after battery replacement
After a battery swap, some CBD6S and Homeline units enter a locked state and ignore handset commands. This happens because the controller loses its calibrated travel reference when power is cut. To re-home it, hold the down button until the desk reaches its lowest physical stop and the controller registers a hard limit — typically indicated by a brief motor stutter. Once re-homed, normal up/down operation and preset programming resume. If the desk still won't respond, confirm the new battery is reading at least 24V before suspecting a controller fault.
