About this replacement
Magura Vyron ver.1 — 2.4V Ni-MH Replacement Battery (6005-1)
This is a 2.4V, 230mAh Ni-MH replacement battery for the Magura Vyron ver.1 electronically controlled hydraulic dropper seatpost. It fits the Vyron ver.1 specifically, using OEM part number 6005-1. The Vyron relies on this small cell to power its electronic shift actuator — without it, the post locks in position and stops responding to the remote.
- Vyron ver.1 actuator compatibility: The ver.1 uses a 2.4V Ni-MH cell on a dedicated voltage rail that drives the solenoid actuator. Later Vyron variants use a different cell format, so confirm your post is ver.1 before ordering. The connector and cell geometry are specific to this generation.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles using a Ni-MH-compatible charger. The cell accepted charge normally, held voltage above the actuator's minimum trigger threshold, and fired the solenoid consistently across repeated actuation tests.
- Ni-MH charge cycle for the Vyron actuator: Ni-MH cells in low-capacity actuator applications are sensitive to trickle overcharging. Use the Magura-specified charger or a smart Ni-MH charger with a delta-V cutoff. A dumb timer-based charger will overcharge a 230mAh cell and shorten its usable life.
Why the Vyron ver.1 post stops dropping mid-ride
The Vyron actuator needs a sustained voltage above its trigger threshold to complete a full travel cycle. As the Ni-MH cell ages, internal resistance rises and voltage sags under the brief current draw of the solenoid. The post may drop partially or not at all even when the battery shows a charge. Replacing the cell restores the voltage headroom the actuator needs to fire cleanly — a healthy cell should hold above 2.2V under load.
Post not responding after fitting a new battery
If the Vyron does not respond immediately after a battery swap, the electronic control unit may need a short initialisation period before it registers the new cell. Wait 60 seconds after installing the battery before pressing the remote. If the post still does not respond, check that the cell is seated fully — the contacts on the ver.1 battery compartment are tight and a partially inserted cell will read as no power.
