Maximising battery life for a cleaner tomorrow

We are Hagal, a Norwegian company creating smart batteries. Our technology extends the lifetime of new batteries and gives used batteries a second life.



Over the next few years, millions of EV batteries will retire from road service. With Hagal´s Rebel technology, these batteries can get a new life in stationary energy storage systems.


To meet the urgent need for batteries at scale, we are building Hagal´s Battery LifeCycle Hub.


This is our production facility for new batteries and Centre of Excellence for testing, analysing and repurposing used batteries. We make sure each battery cell gives green energy until its last breath.
