Leclanché Restarts M3 Battery Module Production After November Incident

Leclanche SA ( (CH:LECN) ) has shared an update.

Leclanché SA has resumed standard production of its M3 battery modules at its Yverdon-les-Bains facility following an incident on 26 November 2025, restoring operations under adjusted conditions while damaged equipment is replaced. After successful test production before Christmas, the company has restarted manufacturing with offline quality controls substituting for a damaged inline test station, a setup that allows it to maintain full compliance and preserve capacity in key assembly steps, with a gradual ramp-up expected to reach near-full output before full capacity returns once new equipment is installed. Leclanché reports only minimal delivery interruptions to customers and says the restart will support continued supply of modules, including battery pack assembly in Germany, limiting operational disruption and helping safeguard its position and customer relationships in the competitive energy storage market.

The most recent analyst rating on (CH:LECN) stock is a Sell with a CHF0.12 price target. To see the full list of analyst forecasts on Leclanche SA stock, see the CH:LECN Stock Forecast page.
